How many species of spiders are there in Washington State?
Thomisidae is the sixth largest family of spiders and contains over 2,000 species worldwide and about 60 species in Washington State. Crab, or running spiders, can be recognized by orientation of the legs as they extend sideways (Figure 23). The two forelegs are often much longer than the two back legs on each side. The front legs are commonly held out and up much like a crab. The body lengths of the common crab spiders in Washington are no longer than 1/2 inch. Crab spiders have eight eyes, with a pair of eyes on bumps on either side of the head and four forward-directed front eyes (Figure 24).
What are the most common spiders in the Pacific Northwest?
The funnel-weavers, house spiders, and grass spiders represent one of the most common spider families encountered in the Pacific Northwest. They are rather non-descript brown spiders with long spiny legs. Agelenids are from 3/4 to 1 1/4 inches long, but some of the larger species can have a body length of one inch and a leg span that reaches three inches long! Their eight eyes form a circle or oval pattern about the front of the spider’s head (Figure 5). Perhaps the easiest recognizable features of this family are the sheet-like webs they spin with a landing in the front and a conspicuous funnel-shaped entrance in the back (Figure 6). The spider often hides in the funnel until an insect lands or crawls over the non-sticky sheet-like web.
What are folding door spiders?
Folding-door spiders are one of our largest ground-dwelling spiders in Washington. Mature adult males are chestnut to brown colored, robust-bodied with long hairy legs, and body length may measure between 1/2 to 1 1/2 inches long (Figure 3). Females are even larger with a more robust abdomen and are darker in color. These spiders are sometimes referred to as the tarantulas of the Pacific Northwest. Despite their frightening appearance, these spiders are unique compared to the other common spider families in Washington, in that their powerful fangs are oriented parallel to each other and move up and down in a stabbing motion, rather than opening and closing about the prey. Folding-door spiders have a single cluster of eight eyes directed forward on a protuberance above the mandibles.
What are the legs of a yellow sac spider?
Yellow sac spiders have pale, long, and slender legs. The first pair of legs are noticeably longer than the rest and point forward. These spiders range in size from about 1/4 to 3/8 inch long and are tan to light brown in color with an indistinct, darker dorsal stripe lengthwise on the abdomen (Figure 13). Two species of long-legged sac spiders live in Washington State. The black-footed sac spider, Cheiracanthium mildei, is native to eastern Washington and lives in trees, shrubs, and on forest floors. The introduced long-legged sac spider (C. inclusum) is more common in western Washington and is more likely to be found inside homes and buildings.
What are cellar spiders?
Cellar spiders (Pholcidae) are also referred to as long-bodied cellar spiders, or vibrating spiders. The body is box-like and brown with banding or chevron markings. The delicate-looking cellar spiders have very long, thin legs (Figure 27). Eyes are arranged in two groups of three on either side of the head, with two smaller middle eyes. Cellar spiders are found on all continents, except Antarctica, but are most common in hot tropical climates. One species of cellar spider, the long-bodied cellar spider, Pholcus phalangioides, is common in western Washington outbuildings, basements, or under outdoor furniture or other undisturbed areas where they build their messy, tangled webs. The webs may have several spiders hanging upside down, as well as dead insects, and the spider’s white egg sacs. To attract prey, the spider may vibrate the web, or spin in a circle creating a blur of dark and light; the vibration also increases the entanglement (these webs are not particularly sticky) of the prey. This spider will invade the webs of other spiders and eat the host, their eggs, and any uneaten prey. Cellar spiders are predators of house spiders(Tegenaria) but are not especially venomous nor are they dangerous to humans.
What are spiders and insects?
Spiders are not insects, but they are closely related to them. Both spiders and insects belong to a group of animals called arthropods . One of the distinguishing features of arthropods is that they have a hardened exterior, or exoskeleton. Mature insects have six legs, three body parts (head, thorax, and abdomen), and are the only group of arthropods with wings. Mature spiders, or arachnids, have eight legs and a body divided into two parts—the cephalothorax (a combined head and thorax) and the abdomen (Figure 1). The cephalothorax of a spider is covered with a plate-like structure referred to as a carapace. The shape of the carapace and its various markings are also important in spider identification. All eight legs are attached to the cephalothorax. As in insects, the legs of each spider are jointed appendages (femur, tibia, and tarsus) that end in two or three small claws.
How many claws does a wolf spider have?
Wolf spiders range in body length from about 1/5 inch to one inch, or so (Figure 14). These long-legged spiders have three claws on each foot, and the cephalothorax is arched. The eight eyes are arranged in three rows. The two medium-sized eyes in the top row are above and behind the two large middle eyes. Four smaller eyes comprise the bottom row.
