'swollen'
Numbers
17 described and many undescribed spp. in our area (Frankenberg et al. 2013)
Identification
Scutellum triangular and shorter than pronotum, protarsi small but distinct(1)(2)
obsolete key to spp. in(3)
key to two eastern spp. in(4)
NB: "Strong intraspecific morphological variation, outdated species distributions, and insufficient species descriptions make identifications problematic. Keys are difficult to decipher, and lack recently described species. These factors have left many museums with large holdings of unidentified or incorrectly identified specimens." (Frankenberg et al. 2013)
Range
much of NA
Habitat
typically found on flowers in open or semi-open habitats
Food
small insects and other arthropods
Life Cycle
"Coupling may involve several males riding around on a single female. Sometimes it allows them to take down larger prey, although coupling individuals have been found each with their own prey as well. Mating occurs with the male mounted on the side of the female" (comment by drswanny).

Eggs · nymph · final molt · adults (coupling) · adults (mating)
