Damp environments, particularly in houseplants with overwatered soil, greenhouses, and near decomposing organic matter.

Larvae feed on soil fungi, algae, and organic matter, occasionally consuming plant roots. Adults do not feed or only consume liquids.

Weak fliers that are often seen scurrying on soil surfaces or flying near windows/light sources. They have a short lifecycle of about 3 to 4 weeks.
