Dwarf spiders

As the common name implies, many of these spiders are small. The ehelicerae are relatively large, with sharp teeth, and the legs have strong bristles. Males may have odd projections on the carapace, which may carry the eyes. Coloration varies from pale yellow to black and some have pale patches or banded legs. Many species attach nonsticky sheet webs to vegetation. Passing insects are knocked down on to the web, where the spider bites them from below with its chelicera and drags them under the sheet.

• LIFE Cycle Females grip the male during mating. They attach egg sacs of various designs to plants, stones, and other surfaces.

• OCCl JRRKNCF Worldwide, mostly in temperate areas. Among vegetation and stones in various habitats, such as woods, grassland, scrubland, and swamps. Dwarf spiders can travel vast distances by "ballooning" on silk threads.

• remark Another common name - "money spider" - comes from the myth that if a dwarf spider lands on you and is twirled around the head three times, good fortune will result.

Wolf spiders

I hese spiders vary from pale gray to dark brown with markings such as bands, stripes, white hairs, and black dots. The "head" area is often narrow, and the front two pairs of legs have many strong spines. Wolf spiders have four large eyes: the rear two face sideways and the two adjacent eyes face forward. They also have four small eyes. These spiders have the excellent eyesight necessary for effective hunting, and most search for prey along the ground or among leaf litter, usually at night.

• LIFE Cycle Courtship can be complex. Females of ground-active species carry egg sacs around with them, attached to their spinnerets. Burrowing species keep their egg sacs in a silk burrow. When the spiderlings hatch out, the mother may carry them around on her back.
