The pronotum looks very narrow and wide for it to be a Lyctus species of 
powderpost beetle.

Hi Cara,

Unfortunately, that sure does look and sound like a powder post beetle to me 
(though it’s hard for me to be positive without the antennae).

If the altarpiece is on open display, you might want to alert the people who 
clean the gallery that the frass will resemble extremely fine sawdust or even 
very light dirt. It is very easily mistaken for other substances.

Luckily these beetles are pretty weak fliers. If you can’t get the object into 
treatment any time soon, you could be able to partially control their movements 
by using a UV lure in the gallery after hours.

Hi Joel,

Size: 5-6 mm

It was found alive, crawling on a painted platform in front of a painted 
altarpiece on wood panel.  I don’t have any photos of exit holes, but the raw 
wood visible on this altarpiece does have plenty of old signs of pest damage. 
This is a loaned object that reportedly has been treated twice with anoxia in 
the last year, for what type of pest activity I am not sure. (It is typically 
on display in a church, however, so the likelihood of re-infestation seems high 
in that kind of environment.) There was no frass visible below or around the 
altarpiece, however this object is currently installed so I wasn’t able to lift 
it up to examine very closely.

Thanks,
Cara

Hello all,
I’ve discovered what I believe is a type of powderpost beetle (photos attached).
Would someone please confirm this ID for me?
Thanks very much for your attention and help,
Cara
