Dorcatoma Herbst 1792
5 spp. in our area (all reach Canada)(1)(2), 16 in Europe(3)

key to spp. in(4)
Holarctic; in NA, more diverse in the northeast (only D. integra is confined to BC-CA)(2)(5)
(it's an "old" genus, so there are species from other continents assigned to it that probably belong elsewhere)
Adults appear in late spring and summer
woody bracket fungi(1)
Life Cycle
Larvae develop within fruiting bodies, or in the wood of host trees ridden by mycelia. Females check out new breeding places, then call males by pheromones.
rarely observed in the field, but easily bred from colonized fungi
