ICO 2019: Widow Skimmer

Another beautiful dragonfly we saw in Texas during the ICO meeting was the Widow Skimmer, so named for the dark patches in its wings that look a bit like mourning cloaks. We saw this species at both the retention pond in Austin, and at the Southeast Metropolitan Park south of Austin, near the airport.

The males are most commonly seen, since they are always on patrol to defend their territories and search for females. Here's a male at the retention pond:



The black patches on the wings were impressively deep and dark, in striking contrast to the white pruinosity.

Here's a side view of a male at the Southeast Metro Park:



Notice the prominent hamules on the underside of the abdomen, near where the abdomen joins with the thorax. The hamules are a sure sign we're looking at a male.

Now for a top view of a different male at this park:



Finally, we did manage to spot one female, resting inconspicuously in the bushes. Here she is:



Notice her tiny, well-separated appendages, wide abdomen, and pale dark patches.

We've seen this species before in a number of places, but I think the most strikingly beautiful individuals were the ones we saw in Texas.
