Discussion
- Model hax was fitted, but little is known about pupal development
Facts
- 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)
