The larvae feed in mushroom mycelium and/or on decaying fungal, animal or plant tissue.

Adults are not known to feed, but likely imbibe liquids from environmental substrates. They can be found mating near situations where the larvae dwell. Adults are often seen coupled, and may crawl around, attached, for some period of time.

These flies have been used in laboratory studies of developmental gene expression (Bulllock et al. 2004).
