Adult female P. regius measure 15 mm (0.59 in) long on average, but can range between 7–22 mm (0.28–0.87 in) long. They may exhibit white or orange markings on the opisthosoma similar to the white markings seen in males, but the rest of the body is largely covered with scales which may be brown, orange, tan, gray, or a combination of those ...
Jumping spiders are a group of spiders that constitute the family Salticidae. As of 2019 [update] , this family contained over 600 described genera and over 6,000 described species , [ 1 ] making it the largest family of spiders – comprising 13% of spider species. [ 2 ]
Phidippus is a genus in the family Salticidae (jumping spiders). [1] Some of the largest jumping spiders inhabit this genus, and many species are characterized by their brilliant, iridescent green chelicerae. Phidippus is distributed almost exclusively in North America, with the exception of two exported species (Phidippus audax and Phidippus ...
Phidippus audax are commonly referred to as "bold jumping spiders" or "bold jumpers". [8] The species name, audax, is a Latin adjective meaning "audacious" or "bold". [8] This name was first used to describe the species by French arachnologist Nicholas Marcellus Hentz, who described the spider as being, "very bold, often jumping on the hand which threatens it". [9]
When P. clarus males find females, the males court by waving their legs and making their abdomens vibrate against the substrate (leaves, the ground, etc.). Males will court immature and adult virgin females, and also previously mated females. [6] As the male dances, he approaches the female and touches the female cautiously once or twice.
Most species in the genus Maevia follow the mating behavior of the gray morph of the M inclemens species. [5] This courtship behavior pattern is standard for all jumping spiders which involves three phases [6] In the first phase, males will utilize a mating display to attract a female's attention for the latter to identify if the male is of her species.
Phidippus johnsoni, the red-backed jumping spider or Johnson jumping spider, is one of the largest and most commonly encountered jumping spiders of western North America. It is not to be confused with the unrelated and highly venomous redback spider ( Latrodectus hasselti ).
Reversing the traditional roles, species that have males consuming females are relatively unknown; the few that do show a male-biased sexual dimorphism.Examples include Allocosa brasiliensis (a wolf spider), Evarcha culicivora (a jumping spider), and the diving bell or water spider Argyroneta aquatica.
