Tiger Wolf Spider

The Tiger Wolf Spider (Tigrosa aspersa), is one of several wolf spiders found in Indiana. Because of its size and affinity for woody environments, it is also known as the woodland giant wolf spider. Even when compared to other species in their family, the Lycosidae, tiger wolf spiders are fairly huge as adults. Males are typically shorter than females, measuring just about 25 millimeters in length. The majority of females are black, while their abdomens can sometimes be dark grey. Males, in contrast, appear significantly lighter and range in color from light yellow to brown to beige.

Tiger wolf spiders do not use webs to capture food as other wolf spiders do. Instead, they stand in wait for unaware prey before overpowering their target with strength and speed. Despite their size, people are not thought to be threatened by their bite.
