Barn funnel weaver spider on a wood floor.Barn Funnel Weaver
(Tegenaria domestica)

This funnel weaver is not as common as the previous species. It is found, however, throughout most of the United States, most notably in sheds and barns, around and in the crevices of doors, as well as in the cracks of rock faces and under rocks and boards.

Description

The female barn funnel weaver is from 7.5 to 11.5 millimeters in length and the males range from 6 to 9 millimeters in length. The cephalothorax is red-brown with a covering of pale-yellow hairs and two pale-gray longitudinal lines. The abdomen ranges from a pinkish to a pale flesh color with a pattern of gray to black patches. The legs are spiny with very pale gray annulations at the distal end of the femurs.

The webs are similar to those made by the grass spiders, but they are typically smaller in diameter with the retreat within the web sheet rather than off to one side.

Life History/Behavior

These spiders have been reported to live for as long as seven years, producing upwards of nine egg sacs. The sacs are placed in many different locations close to the web, often suspended above the web from silk lines. The males are frequently found on the web along with the female from May through July, during the mating season. These spiders can be found in structures anytime during the year.

Medical Importance

Although these spiders are encountered in and around human-made structures, there are no reports of adverse reactions to their bites.
