Male Blue-ringed Dancer. The stripes on the thorax are a deep, royal blue, and the rings along the abdomen and the tip are a lighter shade of blue. 

Blue-ringed Dancers are a fairly common species. They fly from late May through September (with stragglers into October, weather permitting). 

Male Blue-fronted Dancer. The thorax is nearly solid blue except for a few thin black stripes. 

Female Blue-fronted Dancer. Several brown female damselflies are difficult to distinguish from one another. I usually do not attempt to identify brown females or teneral damselflies to species

Female Blue-ringed Dancer at Siebenthaler Fen. You can see just a hint of blue rings on the mostly brown abdomen. 

Another male Blue-fronted Dancer. This is a common and widespread species. They usually fly from late May through September. However, I have one notably late sighting: October 29, 2016 at Spring Lakes Park. (The weather was an unseasonable 81 degrees that day!)

Believe it or not, this is a Blue-fronted Dancer, even though the thorax isn't blue. These damselflies can change colors in response to cold temperatures or while mating. 

This Blue-ringed Dancer was hanging out in curly grass at Spring Lakes Park in Bellbrook. Until 2018, Blue-ringed Dancers were not considered to have any close look-alikes in our area. In 2018, it was discovered that we have Paiute Dancers in Ohio. (See my page on Paiute Dancers for tips on how to distinguish them.)
