Ostoma parking lot
Ostoma ferruginea, Trogossitidae
Size 8-10 mm
These flattened beetles are closely associated with brown-rot fungi (such as Fomitopsis pinicola or Antrodia xantha) and you find them in rotting wood. These were found underneath the bark and/or inside the wood of a large rotting spruce.
This wide angle close-up was shot in 2013 as part of a book project I've mentioned here: flic.kr/p/geivZ3
