The eastern United States is populated by the large and formidable Tiger wolf spider, measuring up to one inch in length. The Tiger wolf spider (Tigrosa aspersa) is a close relative of the much larger Tigrosa helluo.
The Tiger wolf spider: Identification.
The tiger wolf spider is one species of wolf spider.
The stunning Tigrosa aspersa has a narrow, vibrant line of yellow hairs on its carapace near the eyes.
The males are much lighter in color than females and only have a light brown banding at the joints of their third and fourth pairs of legs.
General wolf spider information.
Currently, there are 128 genera and over 2,800 species of wolf spiders. Amongst all those species, the body size of individual wolf spiders ranges from 1/25 to 1.5 inches.
For the record: The largest wolf spider species is the Hogna ingens, the Deserta Grande wolf spider. The female of this critically endangered spider has a leg span of nearly 5 inches.
Perhaps the most distinguishing feature of the wolf spider is its face. This spider has three rows of eyes, four small ones on the bottom, two medium-sized ones on the top, and two much larger eyes in the middle. Wolf spiders are known to have excellent vision for spotting and tracking prey.
Wolf spider eyes have reflective tissue like canids such as wolves and coyotes. This tissue, tapetum lucidum, reflects visible light back through the retina and increases the light available to the photoreceptors—significantly increasing the wolf spider’s night vision.
And just like wolves and coyotes, you can use a flashlight at night to locate wolf spiders by scanning an area and spotting the reflected “glow” from the light’s beam.
The wolf spider has slightly inferior night vision to the jumping spider, which in turn is bested by the huntsman spider.
The wolf spider also has an impressive set of fangs.
