Megalodacne
pleasing fungus beetles
Megalodacne is a genus of large fungivorous beetles in the family Erotylidae, distinguished by their size (9–22 mm), large eyes, and distinctive color patterns of yellow, orange, or red markings on the elytra. Adults and larvae feed on hard bracket fungi, particularly Ganoderma and Fomes species. The genus was established by George Robert Crotch in 1873 and is classified in the subfamily Megalodacninae alongside Episcapha and Episcaphula. Species occur across North America, Asia, Africa, and Southeast Asia, with some exhibiting nocturnal behavior and attraction to light.
