INTRO
The family Erotylidae in the North America consists of 60 species in 2 subfamilies with 11 tribes. The subfamily Erotylinae occurs on fungi or fungus-rotted woods. The larvae of this group are covered with lon scoli and graze the surface of fungi. (Arnett et al. 2002; Bartlett 2004). The species Megalodacne fasicata that is studied is found on Ganoderma species of polypore mushrooms on oak tree (Quercus sp.).

LIFE HISTORY

NOTES
Larvae seems to be living inside the mushroom, however, sometimes get out of it when the environment is too wet.

It was interesting that alive adults were raising their antennae straight up. Most of the beetles species I’ve been collecting were stretching forward.
