Facts

  • C. crystallinus lives mainly as a larvea with 4 instar stadia (ref: Wiki)
  • At emergence it lives for a few more days without eating and lays eggs. In its larval stage it is benthic (ref: Wiki)
  • Chaoborus larva has modified antennae with which is can grap small prey, such as crustaceans, chironomid larvae, olichochaetes (ref: chebucto)

Discussion

  • They overwinter in the larval stage (most 4th instar) but in summer they can also have a second generation which lifecycle is completed in 44 days
