De larven leven in allelei droge substraten (aarde, stof, huisvuil,nesten van dieren, enz.)

De larven prederen op kleine ongewervelden, met name mijten en kevers.

Adulten voeden zich met nectar en worden veel aangetroffen op bloemen en vensters binnenshuis.

The larvae live in a variety of dry substrates such as soil, dust , nests of birds and other animals.

Larvae prey on small invertebrates, in particular on mites and beetles.

Adults are not often encountered in the wild, but more regularly found indoors on windows or in rooms with lots of dust and dry organic matter (disused rooms, attics, chuch towers)
