Abstract

Examination of stomach contents indicated that second-year Ambystoma tigrinum nebulosum larvae consumed Limnephilus sp. larvae but rarely ingested the case. Feeding observations of captive salamanders on caddisfly larvae supported this finding. Extraction of caddisfly larvae from their case was accomplished only when larval salamanders quickly seized the anterior portion of ambulatory Limnephilus sp. extended from their case and vigorously shook the trichopteran from side to side.
