Distribution
Present across most of Europe, eastern , Near East, and North Africa. Distribution records confirmed from Denmark, Norway, and Sweden.
Seasonality
active from May through December in temperate regions.
Diet
Larvae may be phytophagous or saprophagous, feeding on rotting vegetable matter or mining clover leaves. feeding habits not documented.

Complete with , larva, pupa, and stages. Larval development occurs in decaying plant material or within living plant tissues.
Ecological Role
Larvae contribute to decomposition of vegetable matter; some may act as minor leaf miners on clover.
Human Relevance
No documented economic or medical importance. Occasionally encountered in agricultural settings due to clover-mining larvae.
