This afternoon, I encountered an ebony jewelwing damselfly in the building in which I work. The poor thing was floundering by one of the large floor-to-ceiling windows near the front entrance, so I decided to give it a helping hand. My co-worker **REDACTED** took a couple of pictures:
The absence of white wingspots indicates that this is a male damselfly... with the indoor lighting, it is impossible to see the bluish, iridescent sides of the abdomen, but they were plainly visible in the light of day, when I released this little guy in the great outdoors. As his diet consists largely of mosquitoes, he'll repay the favor many times over, unless he gets eaten by some critter.
