These spiders are solid and strong-looking with reddish-brown to black bodies. The males have distinctive long red or red-orange legs from the femora downwards. The females have legs the same color as the body. Females are known to reach a body length of about 25 mm, or just under an inch, including the chelicerae. Males are smaller with a body ...
Male body length ranges from 4 to 6 mm. V. arenata are polychromatic and their abdomen color ranges from white to yellow. [6] Some smaller, vein-like markings on the abdominal area are red. [4] Females can have black, brown, or rusty red colored legs and carapace. The head is small compared to this spider's triangular abdomen.
The spiders dig a burrow up to 55 cm deep, with two trapdoors. Females are approximately 35 mm long, stout, short-legged, and mostly dark brown to black (but the jaws are sometimes red-tinged). The smaller males are approximately 15 mm long, have longer and thinner legs, and the head and jaws are bright red while the abdomen is gunmetal blue to ...

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 ).
Usually found under bark, fallen trees or stones close to the ground. Legs are red and black. The cephalothorax is red, the abdomen is black or sometimes a dark blue. Palps are red and black. Body length of males is 8 to 10 mm, females 12 to 14 mm. The egg sac is 10 to 20 mm in diameter and contains from 30 to 50 cream eggs, 1 mm in diameter.
Spiders, unlike insects, have only two main body parts instead of three: a fused head and thorax (called a cephalothorax or prosoma) and an abdomen (also called an opisthosoma). The exception to this rule are the assassin spiders in the family Archaeidae , whose cephalothorax is divided into two parts by an elongated "neck".
The body of M. plataleoides appears like an ant, which has three body segments and six legs, by having constrictions on the cephalothorax and abdomen. This creates the illusion of having a distinct head, thorax and gaster of the weaver ant, complete with a long and slender waist. The large compound eyes of the weaver ant are mimicked by two ...
