Aegithus melaspis is a species of pleasing fungus beetle in the family Erotylidae. Members of this group are typically associated with fungi, especially bracket fungi and other wood-decaying mushrooms, and are most diverse in tropical regions, including Mexico and Central America. Both adults and larvae are believed to feed on fungi, contributing to the breakdown and recycling of organic material in forest ecosystems.
