Life history and larva of Tenthredo (Elinora) koehleri (Klug, 1809) (Hymenoptera, Tenthredinidae).

Abstract

Bionomics and juvenile stages of Tenthredo (Elinora) koehleri Klug, 1817 are briefly described and the most important larval characters illustrated. Though adults are mostly found feeding in flowers of Geranium, oviposition was observed on Cardamine amara L. and Myosotis palustris L. (Hill). The larvae feed on Cardamine amara L. and on Cardaminopsis halleri (L.) Hayek (Brassicaceae) but not on Myosotis. Adaptations of the larva to its environment and adaptation of the labiomaxillary complex in the adult are discussed.
