Habitat: Found in a variety of habitats, including forests and grasslands, on tree foliage, grasses and other herbaceous vegetation.

Range: Throughout North America (except south-eastern U.S.)

Seasonality: Adults can be found May to August

Trivia: These spiders are well camouflaged, but when they move, as their name suggests, they can move quickly.  This helps them in their role of active hunters.
