Southwestern Damsel Bug - Nabis
Tonopah Desert, Maricopa County, Arizona, USA
May 29, 2015
These are images of a Damsel Bug, in the genus Nabis (subgenus Reduviolus) and most likely a female Nabis alternatus.
Sexing most of the bugs in this family is very simple, with a clear view of the apical abdominal segments.
♀ Females: - The segments are latteraly thin, with a pointy tip, forming a "V" shape, in the dorsal or ventral views.
♂ Males: - The tips are blunt, latteraly thick (club-like) and equipped with two small claspers, one on each latteral side.
The overall body shape, colors, wings and the lack of any large dark coloring on the legs indicates that this Bug is most likely a member of the Nabis subgenus Reduviolus. (5 species in North America)
The two isolated yellow spots on the dark scutellum and a few other minor features, such as the head color (ventral), separate this species from N. americoferus. (the most common and widespread of the look-alike species)
The geographic distribution of both species overlap in the southwest, with N. alternatus reported from Oregon to Texas.
