Abstract
Larvae of the caddisfly Heteroplectron americanum
were fed different combinations of wood, periphyton, and
leaves during a 75-day period. Those provided with leaves
showed the greatest amount of growth, as measured by
dry weight and head capsule width.
Other larvae were placed in sterilized trays
containing either leaves with reduced microbe populations
or previously sterilized leaves which had been allowed to
become colonized with bacteria and fungi. After 18 days
larvae undergoing both treatments had lost weight and
were in poor physiological condition. Clearly a longer
period of interaction between leaves and microbes was
necessary for the leaves to be able to support larval growth.
