Barn Funnel Weaver/Domestic House spider

This spider builds a funnel-shaped web to catch its prey. It usually consists of a multitude of stressed silk threads spun over a flat surface (such as a window sill) near any corner, with a funnel-like structure reaching for the corner, in which the spider would typically reside (hence the name). These webs can become quite large if undisturbed. They act like cord strings, helping the spider glide over them, and once a prey stumbles into the web, it will quickly get attacked, then dragged inside the funnel part and eaten, but very rarely stored underneath the structure.[2]

Females that dwell indoors would usually live for over one or two years on the same web, with some residing for as long as seven years in rarely disturbed places (attics, basement or cellar parts, storage rooms, etc.). Outdoor females perish with cold weather and males rarely live for over a year. In late Fall, an egg sac is made containing up to 50 eggs and put in the very tip of the funnel, protected by the female. The spiderlings will hatch in early to mid April and go over seven molts to reach adulthood.
