Identification
As a member of the Platypalpus, this likely exhibits the characteristic hybotid : small body size (approximately 4-5 mm), a disproportionately small spherical with large dominating most of the head surface, and a compact, somewhat humpbacked . Species-level identification requires examination of subtle morphological characters including (arrangement of ), leg proportions, and male . Platypalpus species are distinguished from related genera such as Tachypeza and Hybos by specific patterns and leg modifications.
Distribution
United States.
Seasonality
Hybotid are generally most abundant in spring, based on observations of the in temperate North America.
Behavior
Members of the Platypalpus are predatory as , seizing with their legs. The front are often enlarged to aid in prey capture. A is used to inject digestive and consume liquefied tissues through extraoral digestion. Males of many hybotid possess modified hind legs, possibly used to grasp females during mating. Like other hybotids, Platypalpus species may participate in the mating swarms that give their , with males gathering in bouncing over prominent objects.
Ecological Role
As of small , hybotid contribute to the regulation of of other dipterans and small in their .
