The imagos have often been found on mushrooms in Scandinavia (Hackman, 1965). Limosina claviventris Stróbl, 1909 - 1 6, 1 g: ex Gyromitra esculenta, 25. 5. 78 (No. 33); 1 o_: 31. 7. 78 (No. 12); 3 i, 2 o_: ex Leccinium scabrum, 31. 7. 78 (No. 30, 32); 2 g: ex Suillus luteus, 3. 8. 78 (No. 34); 1 j, 1 o: ex Boletus edulis, 21. 8. 77 (No. 36). It is a terricolous species, known also from runs and nests of small mammals but the larvae feed probably exclusively on mycelia including the fruiting bodies of mushrooms.

This species has been known to be cavernicolous (DUDA, 1938). The mushrooms are new known media for the breeding of its larvae. Limosina fungicola Haliday, 1836 - 1 6: ex Peziza sp.
