Wolf Spider (Pardosa sp.)

click for large

Pardosa sp., are also known as Thin-Legged Wolf Spiders. This is a female I caught near my watering hose. It was a fair bit larger than the male I caught earlier, probably twice as large. You can compare this female to a male I caught earlier here. Notice how the male has big black furry palps.

Like all Wolf Spiders they are robust and agile hunters with good eyesight. Check out the eyes on this guy. Wolf spiders can be found in a wide range of habitats both coastal and inland. These include shrublands, woodland, wet coastal forest, alpine meadows, and suburban gardens. Spiderlings disperse aerially and consequently wolf spiders have wide distributions. Although some species have very specific microhabitat needs (such as stream-side gravel beds or montane herb-fields) most are wanderers without permanent homes. Some build burrows which can be opened or have a trapdoor. Arid zone species construct turrets or plug their holes with leaves and pebbles during the rainy season to protect themselves from flood waters.
