Summary
The numbers of gill filaments were counted on caddis larvae and pupae from sites with different thermal regimes and on larvae maintained at different temperatures in the laboratory.
Intraspecific differences in gill number were found for both larvae and pupae, individuals from warmer conditions having more gills.
In species having single gill filaments, the increase occurs by the production of gills at new sites. Species with multiple gill filaments may increase the number by both an increase in the number of sites and an increase in the number of filaments per tuft.
The relationship between gill number and dry weight of larvae is discussed.
