Erotylidae is the pleasing fungus beetles, is a family of beetles containing over 100 genera. In the present circumscription, it includes the subfamilies Dacninae, Encaustinae, Erotylinae, Megalodacninae, and Tritominae. In other words, the narrowly-circumscribed Erotylidae correspond to the subfamily Erotylinae in the definition sensu lato. They feed on plant and fungal matter; some are important pollinators (e.g. of the ancient cycads), while a few have gained notoriety as pests of some significance. Sometimes, useful and harmful species are found in one genus, e.g. Pharaxonotha. Most pleasing fungus beetles are inoffensive animals of little significance to humans however.
