The common whitetail or long-tailed skimmer (Plathemis lydia) is a common dragonfly across much of North America, with a striking and unusual appearance.The male's chunky white body (about 5 cm or 2 inches long), combined with the brownish-black bands on its otherwise translucent wings, give it a checkered look.
The black saddlebags (Tramea lacerata) is a species of skimmer dragonfly found throughout North America. It has distinctive wings with characteristic black blotches at their proximal ends, which make the dragonfly look as though it is wearing saddlebags. The black saddlebags is a relatively large dragonfly at about 5 centimetres (2 in) in length.
The wings have a network of veins; between the veins the wings are generally transparent, but may be partly colored. [1] In most Odonata there is a structure on the leading edge near the tip of the wing called the pterostigma. This is a thickened, hemolymph–filled and often colorful area bounded by veins.
