Hermit Flower Beetle, Hermit Beetle
Osmoderma eremicola is a large scarab beetle native to eastern North America. Adults are nocturnal and associated with mature woodland habitats, particularly near tree trunks. The species is notable for producing a distinctive leathery odor and serves as a phoretic host for multiple mite species. Larvae develop in decaying wood and wood mould within hollow trees over a multi-year period.
Prostomis
Prostomis is a genus of beetles in the family Prostomidae, established by Latreille in 1819. The genus contains at least 28 accepted species distributed across multiple continents. Members of this genus are xylophilous (wood-associated) beetles with a documented fossil record extending to the mid-Holocene in Europe. The genus is considered rare in modern faunas, with some species no longer present in regions where they occurred historically.
