Cataclysta lemnata L. (Lepidoptera, Pyralidae) can survive for several years consuming macrophytes other than Lemnaceae

Abstract

Caterpillars of Cataclysta lemnata L. are able to consume parts of a number of macrophyte species other than Lemnaceae. The species can survive without Lemnaceae for several years and can thus not be regarded as a real stenophagous species as is often recorded in the literature. Damage patterns are described and illustrated.
