Another male Stream Bluet. I have found this species at numerous locations, from late May through early September. They live near flowing streams and rivers. Siebenthaler Fen, Germantown MetroPark, the Caesar Creek Dam, and the Great Miami River are good places to find Stream Bluets. 

Male Stream Bluet. When looking at this species from above, notice the thin blue stripes on the otherwise black thorax, and the single blue square near the tip of the abdomen. Only one segment is blue on the top of the abdomen. 

This is a Turquoise Bluet, a fairly localized and uncommon species in our area. They are similar to Stream Bluets, but male Turquoise Bluets have two blue segments at the abdomen tip instead of one. (Skimming Bluets also have two blue segments, but they are not as long and thin as Turquoise Bluets.) 

Male Slender Bluet. We have the western subspecies in our area (Westfall's Slender Bluet). This individual was photographed at Spring Lakes Park in Bellbrook. 

I love this photo of a Stream Bluet with rippling water in the background. (Photo taken at Germantown MetroPark dam.)  

Mated pair of Stream Bluets. The females are greenish in color.

Female Slender Bluet, photographed at Cox Arboretum. I typically see this species in June and July, with stragglers into early August.

This is another Turquoise Bluet. The only location where I have found this species is Clifton Reserve (a tiny park in Greene County, not far from Clifton Gorge). Turquoise Bluets can be found at Clifton Reserve in late May and June. This species lives near streams, but they must be fairly picky about their habitat requirements because I have never seen them at any other locations. 

Slender Bluets are found at ponds and lakes. In addition to Spring Lakes Park, three other good locations to see them are Cox Arboretum, Elk Creek MetroPark in Butler County (the Meadow Ridge area), and Germantown MetroPark. 

Female Stream Bluets sometimes have an extra thin stripe on the thorax (the thin brown shoulder stripe seen here), and thus they might be mistaken for female Double-striped Bluets. 

This is a female Turquoise Bluet. Females can be tricky to identify, and are best confirmed by the presence of males in the area.
