Hesperus: Oklahoma, Kansas, and middle Texas throughout the southwestern states; L. geometricus: world wide in the tropical zone. DAMAGE BIOLOGY EGGS The eggs sacs can be constructed by the females in one to three hours and are approximately 1 cm in diameter. Each female can produce 10 to 20 of these sacs during a lifetime, and each sac may contain 200 to 250 eggs. The eggs hatch within the sac in about two weeks. ADULTS The spiderlings undergo their first molt three to four days thence. In approximately 10 days they emerge from the sac through one to three holes that are about 1 mm in diameter. The spiderlings remain in the nest area for several weeks (135-240 days) where they undergo six to nine molts before reaching maturity. Female black widows can live 850 to 950 days when food is readily available. BEHAVIOR The brown widow spider is the most abundant and is commonly found in urban areas. It may be found indoors; however, favorite outdoor hiding places include the crawl space beneath homes and amongst piles of stored lumber, hollow tile blocks, abandoned vehicles, storage sheds, and stored items on shelves. Within the home, the brown widow may be found beneath tables and desks, behind shutters, in the angles of doors and windows, in the folds of clothing, in shoes, and under objects in dark, little-disturbed areas. The black widow spiders are less common and are generally associated with arid areas (western black widow) and higher elevations (southern black widow). Both can be found in crawl spaces, under rocks, in tiny voids, and in utility ducts.

Daddy longlegs spiders There are at least 50,000 spider species in the arachnid family. Spiders are defined as having eight jointed legs, no wings, no antennae and only two body sections: the thorax and the abdomen. Spiders spend their entire life span capturing and eating other insects (about 2,000 in a year). Even though spiders do a great deal of good for our environment, spiders are greatly feared by most of the population. Most spiders are killed only because they scare people, not because they are actually dangerous to humans. All spiders have some amount of venom with varying degrees of potency. The fangs of a spider are hollow. The venom is injected through the fangs into the victim (usually an insect). The venom will rapidly paralyze the victim and aid in digestion. Fortunately, most spiders are not dangerous to humans because their fangs are either too short or too fragile to penetrate human skin. Spiders do not attack in herds. Spiders do not lay in wait and attack people. Spiders do not lift the covers at night and crawl into bed to bite people as they are sleeping. Some spiders can jump but they are not intentionally jumping at humans to attack them. A spider generally bites a human because it was scared and bites to defend itself. Spiders generally prefer to live in undisturbed areas such as corners of the house or the eaves or in the garden where they can catch insects in peace.
