![]() Such a high degree of parental care is relatively unusual among spiders. Fishing spiders, genus Dolomedes, and wolf spiders, genus Lycosa, are our largest non-webbing spiders in North Carolina. Rather, the nocturnal Wolf Spider is an agile hunter, searching out and consuming its prey at night instead of luring it into a web, like other spiders (and yes. When the spiderlings hatch, they are carried around on the female's back until they are ready to disperse by ballooning or on the ground. The female constructs an egg sac of white papery silk, shaped like a ball with an obvious circular seam, which she then carries around attached with strong silk to her spinnerets. The shape and materials used to form burrows and trapdoors may help to distinguish similar-looking species. The main difference between the two in terms of their behavior is their web-making abilities. Burrows of the Grey Wolf Spider ( Dingosa simsoni) have a circular trap door that is often left open when the spider is out hunting. If you take a closer look at both of the spiders, you’ll see that there’s a minor difference in. In woodlands, twigs may be used to form a palisade around the top of the burrow. Arid zone species build turrets to deflect floodwaters during rainy periods, while others use pebbles to plug their burrows. Most Wolf Spiders are wanderers but some build burrows, either open or with a trapdoor, while others may make temporary retreats in vegetation. Venatrix lapidosa will take small toads and frogs while Allocosa obscuroides has been noted biting and killing a large toad within one hour. According to the Queensland Museum, two Wolf spider species are known to be predators of cane toads. Occasionally, they also appear in Northern California, Nevada and in Colorado.Wolf Spiders mostly feed on small ground dwelling invertebrates, predominately insects, but will attack small vertebrates if given the opportunity. Almost all sightings come from Washington, Oregon, Idaho, Montana, Utah and Wyoming.
