Identification

Separated from similar genera by two long processes pointing backwards from the prosternum between anteriour coxae.

key to spp. in(4)

Range

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)

Season

Adults appear in late spring and summer

Food

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.

Remarks

rarely observed in the field, but easily bred from colonized fungi
