Studies on the Depressariidae (Lepidoptera) of Poland. I. New data on distribution and life history. Notes on the breeding of Semioscopis strigulana (Denis & Schiffermüller, 1775). The paper presents new faunistic data for 51 Polish species of Depressariidae. The most interesting of these are Telechrysis tripuncta (Haw.), Exaeretia mongolicella (Christ.), E. praeustella (Rebel), Agonopterix capreolella (Zell.), A. multiplicella (Ersch.), A. pallorella (Zell.), A. senecionis (Nick.), Depressaria artemisiae Nick., D. hofmanni Stt ., D. libanotidella Schläg. and D. ultimella Stt ., known from single or a few scattered sites in Poland. The caterpillars of 30 Agonopterix Hbn. and Depressaria Haw. species were found; data on their host plants and feeding habits are given. The larva of Semioscopis strigulana (Den. & Schiff.), bred ex ovo from a female, is described and illustrated for the first time. In captivity, the maximum number of eggs laid by a single female was 92. The larvae started to hatch in mid-April and reached the final instar at the end of May and in the first half of June. The young larva is pale yellow with a dark fuscous, almost black, head; the prothoracic plate is the same colour as the body. The middle instar and mature larva are pale green with a darker green dorsal line and a plain, yellowish green head capsule. The larval period of Depressaria pimpinellae Zell. was found to be long, from May to mid-August; the caterpillar fed and completed its development in the spring solely on leaves of burnet-saxifrage (Pimpinella saxifraga L.)
