The Specimen

Argia Damselfly NymphArgia  Damselfly Nymph View 3 PicturesMy friend Willy captured this early instar (Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.) damselfly nymph and brought it to me for identification. It is more robust and stocky at this early stage than the spindly appearance of the later instars (Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.), and its appearance is less familiar.

Posts: 34One reason I think it's Argia, is that this genus is characteristically "stubby" and "robust" through the last instar. Without verification, I think it is the stubbiest of the Zygoptera.
