Abstract
Two colonies of forest tent caterpillar were reared at different densities on trembling aspen foliage in an environment chamber programmed for natural temperatures. Based on direct observation of molting, both colonies underwent five instars which overlapped negligibly in head width. Instar head widths were relatively stable between colonies, but individual biomass was sensitive to the different densities. Instars 3-5 in the less dense colony were heavier than those of the more dense by factors of 1.3-1.9. Development to 10-20% of larvae spinning cocoons took 40 days in the less dense colony and 45 days in the more dense. Size of larvae and adults resembled that of field samples.
