[pestlist] RE: identification help please
Hi Bernice They both appeared to be Plaster Beetles or Minute Mould Beetles or Minute Brown Scavenger Beetles, most likely Corticarina, Corticaria or Cortinicara spp. (Coleoptera: Latridiidae). There is an information sheet on these on the museumpest.net with biological and control information. http://museumpests.net/wp-content/uploads/2014/03/Minute-Brown-Scavenger-Beetle.pdf Andras Szito | Taxonomist/Curator Plant Biosecurity | Entomology Department of Agriculture and Food, Western Australia 3 Baron-Hay Court, South Perth WA 6151 Locked Bag 4 | Bentley Delivery Centre WA 6983 t +61 (0)8 9368 3571 | f +61 (0)8 9368 2958 e andras.sz...@agric.wa.gov.aumailto:andras.sz...@agric.wa.gov.au w www.agric.wa.gov.auhttp://www.agric.wa.gov.au From: Morris, Bernice [mailto:bernice.mor...@philamuseum.org] Sent: Tuesday, 26 May 2015 10:30 PM To: pestlist@museumpests.net Subject: [pestlist] identification help please Can anyone help me to identify these small insects?

Re: [pestlist] practical perspective on BookLouse and Minute Scavenger Beetles
Bernice, let me echo Carolyn's thoughts on these critters. Both the brown scavenger beetle (fungus beetle) and psocids indicate that you have moisture problems. Either high humidity or leakage. A combination of controlling the moisture and housekeeping usually does the trick. Look for leakage, maybe from an HVAC, maybe from related to roofing problems or building maintenance. The last time I dealt with the scavenger beetle we discovered that the mortar around some stone blocks was completely disintegrated. Once it was repaired the bugs left and a bunch of other chronic water problems disappeared!

In one area of the building we know why we have a small cyclical problem with the minute brown scavenger beetle (50%RH and hygroscopic cellulose in a fireproofing material on overhead metal beams). In the other room there is a small HVAC unit with an emergency drip pan underneath and a drain tube that leads to a bucket. We think the occasional drips of water that wind up in the bucket cause the spike in psocids. We hope to work with Faclities to find a slightly better system that the bucket. Ironically we try to call the booklouse, psocids because we find it a little less alarming and helps us keep it in perspective when we are monitoring their numbers.

The second photo might be a kind of Minute Brown Scavenger Beetle. The subfamily Latridiinae: http://bugguide.net/node/view/253122 Perhaps of the genus Cortinicara:http://bugguide.net/node/view/229163 This also has good information:http://museumpests.net/wp-content/uploads/2014/03/Minute-Brown-Scavenger-Beetle.pdf Cheers, Derek Faux, MLIS University of Illinois at Urbana-Champaign Preservation Assistant From: Morris, Bernice [bernice.mor...@philamuseum.org] Sent: Tuesday, May 26, 2015 10:30 AM To: pestlist@museumpests.net Subject: [pestlist] identification help please Can anyone help me to identify these small insects?
