Pagasa nigripes
Pagasa nigripes is a small, dark damsel bug in the Nabidae. Like other members of its , it is ground-dwelling and has a compact, -like appearance. The exhibits wing dimorphism, with individuals either fully winged or having reduced, non-functional wing pads. As a nabid, it is a predatory true with front legs adapted for capturing prey.

Identification
Distinguished from other damsel bugs by its small, dark, ground-dwelling habit and -like appearance. Separated from ground beetles (Carabidae) by true characteristics including and . Differs from plant bugs (Miridae) by lacking the —a notch in the wing margin where the leathery meets the membranous tip. Separated from assassin bugs (Reduviidae) by smaller size; most reduviids are larger, though both share a relatively short rostrum compared to phytophagous bugs.
Habitat
Ground-dwelling; runs across open ground. Specific microhabitat preferences for this are not documented.
Distribution
North America; precise range not specified in available sources. Pagasa occurs in Colorado and other regions.
Seasonality
have been observed from early spring through late fall. No specific data for this .
Behavior
. Runs actively across ground. Solitary, not swarming. Uses front legs to subdue prey, including insects larger than itself. Fossae spongiosae on front tibiae aid in climbing slick surfaces and securing slippery prey.
Ecological Role
of other insects. Damsel bugs as a group are economically important for biological pest control in agricultural systems and are among the most abundant small predators.
Human Relevance
Beneficial for agriculture as a natural pest control agent. Not dangerous to humans; may bite in self-defense but is timid and not prone to biting. Venom used to paralyze prey and initiate digestion; bite to humans would be painful but not medically significant.
