It looks like Anobium sp. to me. The Lyctus I've seen tend to have a thorax 
that is more narrow than their abdomen, whereas Anobium seems like their thorax 
and abdomen are pretty equal in width. Anobium also seems to have it head 
positioned lower, as if the thorax gives it a little neck shield. I found a 
site with a good explanation of identifying the differences between Lyctus sp. 
and Anobium sp. that you may find useful: 
http://ipm.ucanr.edu/PMG/PESTNOTES/pn7418.html  Bugguide.net also has good 
pictures.

For an artifact, I would approach a similar treatment for either -- anoxic 
chamber would be my first choice if you have that available; if not, then 
freeze treatment over heating treatment, which I would be concerned that you'd 
run the risk of over drying the wood and cause cracking. Then clean it really 
well with a HEPA vacuum and brushes.

Hello Everyone,

A mask recently came in with evidence of wood boring pests.  We will be
freezing the mask.  The beetle pictured was found in the wrapping (it was
found dead).  I am wondering, can anyone confirm if this is a Powderpost
beetle vs a Furniture beetle?

In the end, does distinguishing between the 2 really matter? (treatment
methods, severity of damage, one being considered "worse" than the other...)

Thanks!
Todd Holmberg

Dear Colleagues,

I need to purchase an Ultra-low Temperature chest freezer.

So far I've gotten quotes for :
So-Low Chest style freezer Model CH40-22
Thermo Fisher Scientific Revco Model ULT2050-10-A -40C Chest Freezer
Scien Temp34-22A Standard Low Temperature Chest Freezer

Any recommendations, thoughts, comments, likes or dislikes for an ULT chest
freezer ?

Advance thanks, Ann

I am not an entomologist but my money is on cuckoo wasp. Group of solitary 
parasitic wasps - no danger to your collection from theses guys. Although 
perhaps from their host species.

Hallo group,

This is a bit outside the pest scope I usually have to deal with, but I hope 
the entomologists can help:
These small (3-4 mm length), rather pretty wasps emerge year after year in a 
timber framed, inhabited house in southern Denmark in late summer / early 
autumn and search to the windows.
Where they come from has not yet been observed, neither have any signs of 
damage that they might cause where they live/hatch.

Thank you for any assistance!
