Description: Selys' Sundragon is a rather small springtime dragonfly with an unmarked brown thorax and black abdomen. There are small spots along the leading edge of the wings and yellow markings on the abdomen, with a yellow ring around the base of the abdomen. It size range is 38-41 mm (1.5 inches).
Similar species: Selys' Sundragon can be told from the baskettails (Epitheca species) which also fly in early Spring, by the mostly black abdomen that thickens towards the end, bluish eyes, and the small spots basally along the leading edge of the wings. It can be distinguished from its close relative Uhler's Sundragon (H. uhleri) by the lack of orange spots in the wing bases.
North American Range: Selys' Sundragon lives in the southeastern United States from southern Maryland to east Texas, mostly in the Piedmont geographical province. In Virginia, this is mostly a Piedmont species, with some records from the coastal plain. It is apparently absent from western and higher elevation counties where it is replaced by Uhler's Sundragon.
