Van de weinige soorten waarvan iets over de biologie bekend is, leven de larven in rottend hout van loofbomen, veelal in door andere insecten gegraven gangen. Adulten zijn dan ook hoofdzakelijk te vinden in loofbossen en worden daar met name verzameld in vangtenten en minder gevangen in vangnetten.

The larvae of the few species of which something is known live in rotting wood of deciduous trees, largely in mines of other insects. Adults are mainly found in damp deciduous forests near dead or dying trees, with males displaying courtship behaviour on trunks and stumps. Adults are not frequently netted but at proper locations they are frequently collected in Malaise traps.
