Abstract
German
German
Das Beutefangverhalten der Eilarve und Larven mittlerer Stadien wird durch thigmotaktische Reize vorbeilaufender Blattläuse ausgelöst. Larven des letzten Stadiums überziehen Blattlauskolonien mit einem aus Körperdrüsen ausgeschiedenen Klebstoffsekret. Erbeutete Läuse werden ausgesaugt.

Larvae of Syrphus balteatus exhibit three strategies when seizing their prey: 1. passive waiting for single aphid, 2. active seizing of a single aphid, 3. active seizing of a colony of aphids (refers to larvae of 3rd and 4th stage).
