Different dragonfly species perch in different ways. Some perch high and some perch low; some perch horizontally, others perch at an angle, and others hang vertically. I am always intrigued to look at the way a dragonfly is perched and, in particular, to see how the dragonfly is using its legs.
Last week I was delighted to spot a male Stream Cruiser (Didymops transversa) while I was exploring the edge of a creek in Prince William County, Virginia. The Steam Cruiser was perched low in the vegetation at an angle. Stream Cruisers have such long legs that they look somewhat uncomfortable when they are perching.
If you click on the image below, you can get a closer look at the dragonfly’s legs. The dragonfly does not seem to be using its front legs at all to perch and appears to be relying almost exclusively on its middle set of legs. The back set of legs look to be amazing long and are probably more useful for capturing prey than for perching.

Interesting about the different leg lengths and how they might be employed by the dragonfly.
