House spiders belong to the comb footed spiders as do black widow spiders. Two of the more medically important types are the black widow spiders, and the brown recluse spider and its relatives. The only dangerous spiders in the northeast, however, are the very rare black widow and brown recluse spiders. Black widow spiders use their webs to ensnare their prey, which consists of flies, mosquitoes, grasshoppers, beetles, and caterpillars. Black widow spiders build webs between objects, and bites usually occur when humans come into direct contact with these webs. Black widow spiders generally live in trash, closets, attics, woodpiles, garages and other dark places. Females black widow spiders are shiny black when full grown.
Brown recluse spiders have been reported in several widely scattered sites in southern Iowa since 1969. Wolf spiders are often confused with the brown recluse, but they lack the unmistakable violin-shaped marking behind the head.Brown Recluce spiders are approximately 3/8 “ long by 3/16 “ wide, light tan to dark brown with distinctive violin shaped marking on the cephalothorax.Adult spiders are distinctively shiny and dark colored, generally black or occasionally dark brown. Brown Recluse generally occupy dark, undistrurbed sites indoors or outdoors. Indoors they are found in attics, basements, crawl spaces, cellars, closets, and duct work. Outdoors the Brown Recluse is often found in barns, rock piles, stacks of wood or piles of debris.
All spiders have eight legs and silk glands in the abdomen. Unlike insects, which have three main body sections and six legs, spiders have two body sections and eight legs. Tarantulas are spiders (eight legs) and all spiders have venom glands.
Since Wolf Spiders have no webs, the mothers carry their egg sacs with them. Egg sacs of large spiders may contain several hundred eggs. Wolf spiders are characterized by good vision, not capturing their prey in webs and females carrying their egg sacs with them (most do). However, the most pronounced feature of wolf spiders is that females carry their egg sacs with them.
