Nymph Anatomy and Instar Determination

  • Kenneth J. Tennessen


Knowledge of the external anatomy of Odonata nymphs is necessary for learning how to use the keys for identification. Basic morphology and terminology of all structures crucial for identification of Anisoptera nymphs to family, genus and species are described and illustrated in detail beginning with orientation of the dragonfly nymph body and the basic body parts. Data on growth rate and a method for determining the last five instars are included.
