Litargus tetraspilotus
Four-spotted Hairy Fungus Beetle
Litargus tetraspilotus is a small hairy fungus beetle in the family Mycetophagidae, first described from North America in 1856 and more recently recorded in Brazil. It feeds on powdery mildew fungi (Oidium sp.) and has been studied as a potential biological control agent for fungal pathogens on fruit trees. Population dynamics show seasonal variation tied to humidity and rainfall patterns.
