This particular species is *Porcellionides pruinosus*, a woodlouse that is
normally associated with manure heaps or compost heaps, but is occasionally
found under stones, etc.
A check on the grounds around the building may indicate its origin.

I have to say that none of these moths looks like *Tinea pellionella*
or *Phereoeca
uterella. *My guess is that they are all accidentals from outside. I'm
happy to have a look at some specimens, and will be able to say if they are
one of the pest species, but my familiarity with the North American "wild"
microlepidoptera borders on the non-existent, so approaching a local
lepidopterist might be your best bet for a definitive answer.

Hi Megan
The "cases" are sections of a millipede's cuticle (legs missing). The pouch
could be associated with a moth larva, but might just be a bundle of fluff
that has become stuck to the side of the trap. The millipede bits didn't
get there on their own, so I wonder whether some sweepings have
accidentally found their way into the trap?

The only species I know about is *Trixagus dermestoides*. Its larvae live
in soil, feeding on fungal mycorrhizae associated with the roots of trees.
The adults are attracted to light, which is probably why this one ended up
indoors.

Hi Megan
It looks rather like a *Trixagus *species (Throscidae) - if there's just
the one, I'd put it down to an accidental intruder.

This is the Silver-striped Hawkmoth, Hippotion celerio - its caterpillar
feeds on plants such as bedstraw (Gallium) and willowherb (Epilobium). This
individual was presumably attracted to light.

Hi Megan
This is a *Monopis *species - almost certainly *M*. *crocicapitella*, the
Pale-backed Clothes Moth (though it is known in the US as the "Bird Nest
Moth"). It is becoming a frequent pest in domestic and public buildings in
Europe, or at least it is coming to our notice more frequently, especially
as it is attracted to *Tineola *pheromone traps. Although the adults can be
abundant, finding larvae is proving much more difficult.

2 is a *Liposcelis *species
9 is a *Dorypteryx *species
(both booklice, as others have pointed out, but note that *Liposcelis *are
much more destructive than *Dorypteryx*)
10 appears to be *Anthrenus *(carpet beetle), but not enough detail to say
which species. Might well be the adult of the larvae in 1 and 7.

Casey and Matthew -
I think your suggestion that this might be a dermestid is quite reasonable,
given the compact shape and the presence of scales on the thorax and wing
cases. However this doesn't match any of the dermestids that I know, and
there are other families of beetles with scales, notably the weevils and
bark beetles (Curculionidae). In this case the asymmetric scale pattern
gave it away - most bark beetles are rather plain, but this genus has a
couple of species with such a pattern. I used an old book that I've had for
over 50 years to make the initial identification, and confirmed it with an
internet search for images of the genus. (There's a limit to what I can
keep in my head!) The other clue that I had was that Simon mentioned dozens
of beetles trying to get out. In my experience that most often results from
a mass emergence from firewood.

Hi Simon
This is one of the bark beetles (Scolytinae) - I would say it is *Hylesinus
fraxini* or a close relative. They are usually associated with ash trees (
*Fraxinus*), and tunnel under the bark. When they occur in large numbers
indoors, the first thing to inspect is any firewood. It is most likely they
are emerging from that. They do not present a threat to the building or its
contents, except that dead individuals provide food for *Anthrenus* larvae.

The moth in pics 1 & 2 is a *Monopis *species, almost certainly *Monopis
crocicapitella*, which is turning up  frequently on pheromone traps in
buildings in Britain, but occurs worldwide. To be certain of the
identification requires a genitalia prep. Happy to do that for you if you
can spare the specimen. Pics 3 & 4 show *Dorypteryx domestica*, as far as I
can tell from the photos. This is a species of booklouse that appears to
occur frequently in museums and art galleries, but I don't know of anywhere
that it has been shown to do much damage. It is certainly less damaging
than *Liposcelis*.

Hi Forrest
Have you any reason to doubt the original identification suggestions?
If you want a definitive species name on it, I think you will have to send
the specimen to someone who is familiar with the North American Siricidae.

Hi Johanna
As others have suggested, a specimen or magnified photo would be best to
get a definitive name, but looking at your pictures, I am quite sure that
the insect is a thrips (Thysanoptera). These insects regularly squeeze
themselves into picture frames (they have evolved to insert themselves into
very narrow spaces in the plants on which they feed). They will do no
damage themselves, but occasionally a dead thrips can act as a focal point
for mould, which may damage works on paper, so they are best removed from
the frames.
Best wishes
Tony

Looks like of one of the woodwasps (Siricidae) to me.
They take a long time (several years) to develop, so infested timber can be
sawn and incorporated into structures before the wasps emerge. Or they
might be in firewood.

I interpreted the two small dots at the back of the head as markings,
rather than ocelli, so dismissed Lygaeidae. The wing configuration seems
much more like Miridae, perhaps somewhere near *Hoplomachus*, but I don't
really know the North American fauna.

Hi Lindsey
Your second insect appears to be a silverfish (*Lepisma saccharina*) or
close relative. If the property you mention is coastal, this could be one
of the "rock-brats", *Petrobius, *which are a bit more substantial than
silverfish. *Petrobius *sh*o*uldn't be a problem (other than indicating
poor sealing of the building), but silverfish can be damaging to paper and
other artefacts.

I can't see this is *Plodia *or *Ephestia*. It resembles  the European
*Scrobipalpa
costella*, but I'm not sure whether this occurs in WA (or anywhere in
N.America).

The psocid is *Dorypteryx domestica *(a minor pest if at all). The
"dermestid larva" is a Bristly Millipede (*Polyxenus *sp. - signifies a
damp environment, but not a pest).
I'm not sure about the moth - not a familiar British species.

I'd say this was a species of *Trixagus *(Elateridae). They breed in dead
wood, but to my knowledge do not affect sound structural timber.
Although it looks similar this is not a dermestid or anobiid!

I think the most likely answer is a calliphorid puparium. A bluebottle's
sense of smell will guide it to potential food sources, even bricked-up

One of the *Chalcophora *species - larvae feed in decaying pine wood, so

These flies are Black Fungus Gnats - Sciaridae. They may be breeding
indoors in pot plants, or in soil outside, or in rotting wood. They do
breed in fungi as well!
No threat to your collections, excepting as food for Anthrenus. It's
possible they may be attracted to lights at night, and are entering through
an open window.

Re: [pestlist] RE: identification

2015-05-12 Thread Tony Irwin

Enlarging the photo shows that these are booklice (psocids or Psocoptera).
The colour, shape and behaviour are not quite right for Latridiidae. But
what Tom said for plaster beetles goes for booklice as well. I would
suggest these are coming in with the wooden containers, and unless you have
damp problems elsewhere in the museum, they shouldn't become a pest with
you.

 We just found these tiny little pest in our tea that is sold in the shop
 and served in the café at our museum. Both are situated in the museum with
 easy access to exhibitions. Can anybody help in identifying them, and are
 they a threat to the museum objects? They seem as if they live in the
 wooden containers that the tea arrive and are sold in, as seen in the
 picture. They are approx. 1mm long and brownish/grey in colour.



 Would really appreciate any help!

  I found these three - out of maybe a dozen all together - on two window
 sills of our rare book storage. The room and the window sills have
 been cleaned well within the past year and are pretty routinely
 monitored. Other than multicolored Asian lady beetles which try in droves
 to get in through the windows in fall, this is the first I've seen of pests
 in this area. (We made efforts last fall to re-seal the windows, since some
 lady beetles were clearly getting in in previous years.)

 Image 5  shows what appears to me to be a  beetle which is about 4 mm
 long in with brown and black stripes.

 Image 6 and 7 show what I am concerned may be carpet beetles. They are
 about 2.5 mm long and have varied light reddish  brown and black
 markings, though i don't see any very white areas, which I'm used to
 seeing on pictures of carpet beetles.

To me, they look more like beetle larvae - Cryptophagidae or Latridiidae
perhaps. If they are, this might indicate a humidity problem in your
bedrooms, as they often occur with outbreaks of mould. Something to
check... :-)

 Happy Saturday!



 Over the past few months I’ve found a few (~4-5) of these small red larvae
 on bug traps in our bedrooms. See attached images. They are about 1mm long
 when I’m finding them. From what I could tell, I think they might be
 webbing clothes moths larvae in very early stages. Am I correct, or is it
 an entirely different insect?



 Thank you!

 Robyn

 Hi All,



 Nice to “meet” you!



 I need some help identifying an insect that was seen on one of our gallery
 walls today (5/8/2014) in Phoenix, AZ. It measures about 2 mm long.



 Any suggestions would be greatly appreciated.



 Thank you!

Hi Betsy
Although Thylodrias does have clubbed setae, they are not arranged in the
sprays that are shown here, nor does it have the tail plumes evident in
your creature. This is Polyxenus, the Bristly Millipede. It is known to
congregate indoors occasionally, usually in bathrooms or unheated bedrooms
where condensation produces the conditions for mould growth  (Polyxenus
grazes on mould and algae). They are unlikely to cause any damage to
collections, and drying and cleaning the store thoroughly should resolve
the problem.

 We had a recent invasion of small pests that I am having difficulty
 identifying. I thought they were carpet beetle larvae but an entomologist
 on bugguide.net has suggested bristle millipede. They were found crawling
 all over a white wall in a textile storage room, following a water leak
 through the exterior wall. We have in the past found old dried up dermestid
 casings on some of our textiles but we don't know if the textiles came in
 that way or if the evidence is due to recent activity. It's a huge
 collection that is just now being properly catalogued. There is
 surprisingly small amount of damage to the textiles overall so it seems
 more likely to me that these larvae came in through the leaky building
 envelope. The images for both these pests are quite similar, however,
 millipedes are not usually mentioned as museum pests and we have not seen
 adult millipedes to date but we did find one carpet beetle last year.
 Thanks for your help.

I'm surprised to hear the suggestion that these are fly spots. It looks to
me like the book has been damp at some time and this is mould growth, the
spots being patches of fruiting bodies, but it's always difficult to be
sure from photos. The first photo shows that the spots are present close to
the spine of the book. Can't see how flies could have squeezed in between
the pages to do the damage.

 Pascal,

 I think you're right about these being fly feces. I've conducted
 considerable research on house flies and other filth flies throughout the
 Middle East and elsewhere. Our own notebooks, papers, clothing and other
 items quickly were transformed to resemble the damage on the book you
 imaged. Damage from termites would tend to be far more significant.
 Cockroaches may also chew on the edges of pages and also leave their feces
 behind. Last but not least, book lice are likely to cause some damage, but
 what you've depicted appears to me to have resulted from flies and / or
 cockroaches.

 Rich

 Hi,

 has anyone seen such a damage on a book before?? The book is about 300
 years old and was transported from Yemen to Austria long time ago and is
 now in the national library. I think it looks like fly droppings but I am
 happy for other suggestions!! We have no idea why this book was so
 attractive for the flies. The spots can be removed mechanically and have a
 small relief, bus some stains remain.

 Thank you very much,

 Pascal

Looks very like Tineola bisselliella - the webbing clothes moth. This can
be a persistent museum pest, feeding on a variety of animal derivatives,
especially wool. Usual action would be to get the identification confirmed
(from a specimen) then monitor using baited traps to establish the extent
of the problem.

 Can anyone tell what this beetle is? The body is about 1/4 inch long and
 the antennae are in three segments (not clubbed on the end). It is black.
 Is it a black carpet beetle?

Laura -
The standard work on British Booklice is New's Royal Entomological Society
Handbook (2005). You can find a reference to it and other literature (most
of which deals with free-living, rather than domestic species) at
http://www.brc.ac.uk/schemes/barkfly/literature.htm
Liposcelis can certainly do damage in a collection, feeding on insect
specimens, for example. They will attack a variety of materials as well as
mould. Starchy products are very attractive, so anything in the archives
with starch-based glue will be fair game for them. Generally, the amount of
damage is normally small, and associated mould growth is more likely to
cause long-term problems. If you can achieve relatively low humidity in the
archive stores, this will help.
Also note that increasing housekeeping could make the problem worse if it
involves damp cloths rather than vacuum cleaners.

 Dear Gretchen,



 Thank you so much for your information.

 Our RH is closely monitored by a BMS and local tiny tag systems, and has
 been staying within range.

 The housekeeping is done every few months, so I might just increase it for
 the moment and monitor, as it is only a very small increase in population.

 Best wishes,



 Laura

 Psocoptera are generally considered a pest.  They feed on microscopic mold
 which indicates that the relative humidity is too high.  From personal
 experience I experienced a huge increase in population just prior to a mold
 out break.  At the very least they are an environmental indicator.

 The good news is that they can be easily controlled through improved
 housekeeping and reduced RH.

 Good luck.

 Dear all,



 I was wondering if anyone could give me their opinion on the Order
 Psocoptera.

 As far as I can tell we have a number of different types, such as
 Dorypteryx-domestica, Liposcelis-bostrychophila, Ectopsocus Briggsi and
 Psyllipsocus Ramburii.

 What I would like your thoughts on is – are all/any classed as a danger to
 archive material (books, textiles, photographs)?



 I use a number of different sources (online and books where possible), but
 if anyone knows of specific books that are handy for identification this
 would also be great!



 Kind regards and thanks,



 Laura Castle

 I'd appreciate help identifying this pest - it was reported that there
 were many crawling in office areas within an historic house setting (I
 didn't see them in place, but got this specimen of 2).  The body shape
 looks like a tick to me, but I only see three legs.  Could it be a flea or
 a bedbug?

 Thanks for help!

Can you tell us where the fly was found? It looks like a species of Fannia,
but difficult as it's so badly faded and eaten. In any case, it's not a
pest species, but whatever's been eating it probably is!

 Hi there,



 I think it might be Dorypteryx domestica, a type of cave barklice related
 to booklice. I used to find them in the museum where I worked, usually in
 damp places along with plaster beetles and booklice.

They look very much like Dienerella (Latridiidae). A dorsal view would help
confirm the genus, but specific identification will be difficult from a
photo. They are one of the mould beetles, and are likely to be associated
with the lunch room, rather than the archives, unless your storage
conditions are rather damp? ;o)

  Hello,

  We have been finding quite a few of these very small insects in our traps
lately. I'm not sure what they are. They remind me of powder post beetles
but being an archives that doesn't make a lot sense to me. This trap was
located in our lunch room under the sink.

  Any help that can be offered is greatly appreciated.

Hi Melissa
Just to expand/correct Alex's reply :
5 is a paper wasp (Polistes or close relative)
6 is a woodlouse (=slater) 
7 is a cuckoo wasp (Chrysididae)

None of these creatures (with the possible exception of the cockroaches) is 
likely to do much damage to your collections. My main concern would be that if 
dead insect material builds up, then other more damaging pests might thrive. 
Regular cleaning and monitoring, as you describe, will be the best defence.

Best wishes

  Hi Melissa


  I don't really see anything of real concern in this group. We do tend to find 
large numbers of bugs in and around buildings in the tropics.


  Most of the bugs (and gheckos) are common, but I don't have the scientific 
name for them. The list is:
  1) Centipede (predaceous on other insects)
  2) Cockroach (omnivorous - will eat just about anything)
  3) Ghecko (predaceous on insects)
  4) Ghecko with optional moth (predaceous on insects)
  5) Wasp
  6) Millipede or slater (feed on decaying plant material, timber)
  7) Fly
  8 and 9) Moths (probably adults of a lawn grub or similar)
  10) Spider
  11 and 12) They look like click beetles (feed on plant material and are 
attracted to light.


  I'm in Hawaii at the moment, but will send you a list and some photos of some 
of the bugs we commonly find in the tropics when I return to Australia.


  Best wishes
  Alex

Hello pest list, 





We are working at the Tonga Traditions Committee (TTC) in Nuku’alofa, the 
capital of the Kingdom of Tonga. We have an historical archive with mostly 
paper and photographic material. There are also textiles, wood and metal items. 
 





An Integrated Pest Management Plan was introduced July 2011 and we have 
happily caught too many insects to count. Given the tropical climate, a 
building that is not sealable, the vast array of insects and pests, and the 
limited resources here, we have been very successful in reducing the number of 
insects week by week using what is available - a can of Mortein surface spray 
and black plastic small square cockroach bait holders and squashing/removing 
them. We have rodent traps, sticky traps, cleaning, waste removal and ongoing 
inspections and awareness training. Our archive is air conditioned which is the 
best deterrent for tropical insects and pests, but power outages occur and can 
go for days or weeks especially in cyclone (hurricane) season.  





I have been training the staff in IPM, insect capture, ID and which type of 
insects cause what damage to paper, photos textiles etc. I now I am hoping that 
some people on Pest list have time/inclination to help us add in more accurate 
information. I’ll be putting together a powerpoint for ongoing training of 
staff here and other record keeping/archives/museums in Tonga, so any 
information given will be shared around.  





If any one has the time, we’d be most grateful to find out more about our 
insects/pests and what specific damage they do to collections.  

I have attached 10 photos and here are the file titles to make it easier to 
respond. There are more varieties than this, but these are the main ones, some 
files are different angles for id.  





Also, If there is any one else on this list from the Pacific or other 
island states, I’d love to hear from them as well.

They are probably Dorypteryx domestica, a species that has been turning up
more frequently in European museums in recent years, and is known from the
United States.
It is not clear whether they cause much damage to objects or simply graze on
mould in damp areas.

  Hello,



  We have found several of these small insects in different traps located in

tiny. We would really appreciate some help in identifying them.

They are moth eggs. Many species of larger moth will lay their eggs on just
about any surface, no matter how apparently unsuitable. In this case the
newly hatched caterpillars were destined to die anyway. They would be
unlikely to cause any damage to the painting.
The best course of action would be to keep moths out of the building. Either
fit fly screens on all the windows, or avoid opening them when there is a
light on. But sometimes it is difficult to get the message across to staff
who are uncomfortably hot, and feel the need for a bit of fresh air.

  Subject: ID insect eggs on painting surface



  Greetings Pest List Community -



  Just above the lion's head on the surface of this oil painting, insect (?)
eggs were discovered this morning.



  The painting is on exhibit, the eggs are newly attached (whatever laid the
eggs ignored the do not touch sign).



  My guess is moth eggs.



  I welcome a real entomologist's opinion and advice about what to do next.



  Thanks,

It's a beetle larva, and doesn't appear to be a dermestid, but I'd hesitate
to go beyond that.
A couple of possibilities are Cryptophagidae or a young Cleridae, but I
think you'd need to show a specimen to a coleopterist to be sure.

Agreed the adult is a Dienerella species, though it doesn't look quite right
for pilifera. But no doubt they all have much the same lifestyle.
However, I don't think the larva is Dienerella - the presence of urogomphi
(posterior spines) excludes any Latridiidae (as far as the larvae are
currently known).

  The adult appears to be a Little brown beetle, Dienerella pilifera. Here
is a fact sheet from museumpests.net on the Latridiidae, Minute Brown

  Thank you everyone for the responses.  I peeled back the plastic that I
had over the sticky trap in order to get some better pictures and possibly
found an adult.  To my uneducated eye, the adult looks like Cleridae in
shape but not coloration.  If it is a Cleridae of some sort, how alarmed
should I be?

Hi Kate
Your picture is of a female non-biting midge (Chironomidae) - they are often
abundant near water, where the larvae live, and swarms of males can
sometimes be a nuisance. They don't pose a threat to the building or
contents, but can be annoying for visitors (and staff!).

  Hello,

  I've recently found these flying insects inside and outside of the
historic building in Virginia where I work.  I don't recall ever seeing them
before, but this June they are out in abundance.  They are just under a
centimeter in length and are yellow-green in color [please see attached
photograph].   I'm new to IPM and have checked all of my resources without
coming up with an identification.  Could they be fungus gnats?  Any help
would be very much appreciated.

  Thanks,
  Kate Hughes

They look like Noctua pronuba - in Britain it is known as the Large Yellow
Underwing. You're correct - they are not a threat to the collections, except
when they die, there's quite a few potential meals for other pests in one of
them!
They are attracted to light, and I'd suggest they flew in through an open
window some evening.

  Hello,



  During the deinstallation of a gallery, we came across two (deceased)
moths and after looking at the great online resources from this group, I do
not believe these are dangerous to the collections. I would feel more
assured having some of your educated eyes look at them.  I am curious how
the two got in the gallery space.



  Thanks for any assistance you can provide.

It is  bostrychid borer, known as false powder post beetles. 
There are a lot of species, some like this with large spikes on the rear of the

It is probably Sinoxylon sp, but I do not know the species.

  Greetings:



  This insect was found under a wooden bench in one of the galleries. It is
now in a few separate pieces.



  Thanks for your help!

If the larva is that of an Odd Beetle (I have some doubts), then it is a
potential threat to the collections if they contain silk or wool. It would
be worth checking any upholstery containing these materials for damage.

  Whitney -

  The beetles are not a direct threat to collections.  It looks like they
are a click beetle (Elateridae), a type of darkling beetle (Tenebrionidae),
and another one I can't quite make out.  The larva appears to be an Odd
Beetle.  It's one of those strange dermestid beetles, whose larvae feed on
protein materials.

  Hello all,

  Yesterday, I discovered a pretty gnarly network of spiderwebs in one of
our furniture storage areas and, upon cleaning them up, found three dead
beetles and a live (!) larva. I am fairly new to insect ID and would love a
little help identifying the bugs. I have attached some (admittedly pretty
poor) photos and would appreciate any insight you might be able to share.

  Thanks very much!

I don't think these are ground beetles. It would be very unusual to find this 
many 2mm ground beetles together, and none of them is showing the elongate 
antennae typical of Carabidae. Moreover a detached leg in DSC09083 is clearly 
not from a ground beetle. My guess is that these are Lathridiidae, which are 
typically this size, and can occur in large numbers indoors. They are sometimes 
called plaster beetles, and are normally found in slightly damp situations, 
where they feed on fungal hyphae. As a rule, they are not damaging to 
collections, but the source of them should be identified, as they could 
indicate a damp problem.

  I should have sent measurements, although that might not change your ID. The 
specimens are approximately the size of a flea (about  1/8 inch or 2/10 
centimeter long). Is there a species of ground beetles this small?

  Ryan -

  They appear to be ground beetles (Carabidae).  In warm weather, they often 
are attracted to exterior lighting, crawl around and up the building and enter 
through cracks and crevices.  They are not a direct threat to collections, 
however their carcasses may be fed upon by carpet beetle larvae.

  Hello all, 

  I recently found these little guys in a historic house on property. Here are 
the environmental conditions:

  · Specimens were located almost exclusively on 2nd floor
  · Specimens were found on wood floors (unfinished) with gaps in 
between boards and an inaccessible void underneath
  · Specimens found  mostly under beds and on insect monitors
  · A few specimens found on a wool blanket (dead) folded on a colonial 
era bed

  Any idea what these insects are and if they pose a threat to collections?

  Thanks,

Hello,

I have recently discovered this beetle near wooden objects in our
collection with small, round flight holes and powder like frass.  It is
similar to a powderpost beetle, but the antennae do not show the
distinctive two segmented club at the end which is noted in any
literature I have read.  Does anybody have any idea who this little guy
is?

With Thanks,

Roberta Sealy

Assuming I'm looking at the correct images, they are from left to right,
Stegobium paniceum adult; a seed (not pest); a dermestid larva exuvium; and
a tineid larval case (like that of Tineola pellionella).

  Hello - we received the email below - the images were in the rar
compressed format. Rar is not native to many computers so I've put his
images on a page on the museumpests web site. If you'd like to help him out
please go to http://museumpests.net/temppests and view the images.



  As I usually do, I also suggested that he join our list. Until he does
that, which you won't know unless he sends something to us, please send your
answers to the list (just so others can follow) and to him,

  P.S. - I think we had this pest come through a couple weeks ago - must be
the season ?

  Dear Sir/Madam,



  Please attached to find a zipped folder including pictures of some insects
we encountered in fur store of our small zoology museum. I wonder if you
have chance to identify those insects? (I think they are two adults, two
larvae and one pupa. One adult may be a black carpet beetle.) (By the way, I
am a cell biologist, not an entomologist).



  Thank you for your help in advance.
