Aurora Damsel (male, mating pair)

An Aurora Damsel (Chromagrion conditum) was spotted along the shoreline of a small pond located in Prince William County, Virginia USA. Aurora Damsel is a new species for my life list odonates.

This individual is a male, as indicated by his coloration and terminal appendages. Speaking of coloration, notice the underside of the male’s thorax is yellow — a key field mark for Aurora.

A mating pair of Aurora Damsel was spotted at the same location. This pair is “in tandem“: the male is on the upper-right; the female on the lower-left.

After copulation, Aurora Damsel engages in a form of guarding behavior known as “contact guarding,” in which the male and female fly “in tandem” to egg-laying sites. Contact guarding is used by most species of damselflies and some species of dragonflies to prevent aggressive males from hijacking the female.

Female C. conditum is polymorphic, including two morphs: blue coloration similar to male; or with an entirely yellow thorax, as shown above.

It’s helpful to take photos of mating pairs of damselflies, especially “in tandem,” since males and females of the same species can look quite different. The preceding photo is slightly overexposed. As a result, the yellow coloration on both the male and female looks a little washed out.
