Litargus
Erichson, 1846
hairy fungus beetles
Litargus is a of mycophagous in the Mycetophagidae, commonly known as . The genus contains at least 20 described distributed across the Americas and Europe. Members feed on fungal growth, particularly , and are associated with fruit trees and other vegetation. At least one species, L. tetraspilotus, has been studied for its seasonal and potential as a agent.

Habitat
Fruit tree orchards and vegetation supporting fungal growth; specifically documented from citrus plants (Citrus nobilis, C. sinensis, C. limon, C. reticulata), Diospyros kaki, and Prunus persica. Associated with humid conditions that promote development.
Distribution
Americas: Brazil, Mexico, Guatemala, Nicaragua, Panama, Argentina, United States, Canada; Europe: Denmark, Norway, Sweden.
Seasonality
Spring shows greatest abundance; autumn shows lowest abundance. Activity correlates positively with rainfall and .
Diet
Mycophagous; feeds on Oidium sp. and other (Erysiphaceae, Ascomycota).
Life Cycle
Laboratory rearing documented at 22.05±1.44°C and 55.68±10.70% RH; laid on -bearing substrate; separate larval and pupal rearing with fungal food source. Specific developmental durations not established from available sources.
Behavior
Seasonal fluctuation driven by humidity and rainfall patterns; shows preference, with significantly higher abundance on citrus compared to other fruit trees.
Ecological Role
Mycophagous feeder on -pathogenic ; potentially regulates fungal on fruit trees in agroecosystems.
Human Relevance
Potential agent for in fruit orchards; poorly studied relative to other mycophagous .
