C. americanus lives mainly as a larvea with 4 instar stadia (ref: FedoSwif1972)
At emergence it lives for a few more days without eating and lays eggs. In its larval stage it is benthic (ref: Wiki)
Chaoborus has a one year life cycle; body length of instar IV can grow from 9 to 12 mm. (ref: FedoSwif1972)
Chaoborus larva has modified antennae with which is can grap small prey, such as crustaceans, chironomid larvae, olichochaetes (ref: chebucto, Wiki)
Model hep was fitted, since little is known about pupal development
Chaoborus larvae have an aspect ratio of 0.08 (estimated from photos), so wet weight (g) relates to length (cm) as 0.0157*L^3 (using cylinder shape). A 1.6 cm larva has a dry weight of 0.7 mg and a wet weight of 41 mg. The dry/wet weight ratio is about 0.017, which has been used.
