Tools for instar determination of European caddisfly larvae (Insecta: Trichoptera)

Department of Functional and Evolutionary Ecology, Division Limnology, University of Vienna, Althanstrasse 14, A-1090 Vienna, Austria.
Trichoptera biometry wing length head width correlation

Abstract

The paper explores the adult-forewing-length to larval-head-width relationship as a basis for instar determination of final instar caddisfly larvae on a family level. In addition, reference data from published sources were used to extract series of percentage-head-width increments and factors-of-increase for penultimate to first instars. This material provides estimates for head widths of earlier instars on the family level.
