The Arizona brown spider is a member of the Sicariidae family. As its name suggests, it is found primarily in the state of Arizona.
Size: 0.83 cm (0.33 in)
Color: They are yellowish to light brown in color.
Other Characteristic Features: There are brown or violet markings on their head, similar to that of a violin.
Loxosceles arizonica
The sacs where the eggs are laid are yellow.
After hatching, they leave their original web.
