Identification
This is a moderately-sized, widespread, but fairly uncommon species of the south-central United States. Its face is pale, but quickly turns black in males. The thorax is brown in front with a pale cream-colored middorsal stripe. This area becomes pruinose blue in mature males. The sides are cream colored and divided by a brown stripe on the third lateral suture. The wings are deeply tinged with amber along the front fifth of e
ach wing, especially towards the tips and there is a dark brown stripe on either side of the midbasal space. The legs are brown basally and become black beyond. The abdomen is brown with dark middorsal stripe and the middle segments are strongly depressed. The abdomen becomes dark with a powder blue covering dorsally at maturity.
Size
Total length: 47-52 mm; abdomen: 31-36 mm; hindwing: 36-42 mm
Similar Species
Female and teneral Golden-winged (L. auripennis
) and Needham's (L. needhami
) Skimmers have longer abdomens and the sides of their thorax are light brown. Young Spangled Skimmers (L. cyanea
) are smaller and have a bicolored pterostigma. Comanche Skimmer (L. comanche
) also has a bicolored pterostigma and white face.
Habitat
Marshy ponds, lakes, borrow pits and slow flowing streams.
Discussion
This species was considered a variation of Spangled Skimmer until detailed morphological differences between the two species were described. Little has been published on its behavior, but it is a wary species. Males are typically found patrolling in small numbers around ponds and borrow pits. Often only one or two individuals will be present around what would seem suitable habitat.
Distribution
Eastern U.S. from New York to Florida and Texas.
