Family Depressariidae Hodges # 0922
(Formerly Depressaria pastinacella)
Caterpillar foods: host plants containing furanocoumarin – including Wild Parsnip (Pastinaca sativa) and Heracleum. (Information from the Berenbaum Laboratory at the University of Illinois)
Introduced from Europe – first detected in North America in 1869. I keep hoping these caterpillars will eat enough Wild Parsnip – also an invader from Europe – to control its population. So far I don’t see much of an effect.
