Philodromus praelustris
Resplendent Running Crab Spider
Philodromus praelustris is a running crab spider in the family Philodromidae, found in the United States and Canada. It has an annual life cycle and is known to occur in orchard habitats in Ontario. Females are capable of producing multiple egg sacs, with laboratory observations recording up to 12 sacs containing over 200 eggs total, though fecundity in natural settings appears lower. The species disperses primarily by bridging—casting air-borne web loops that catch on distant objects—rather than by ballooning.
