The Barn Funnel Weaver, scientifically known as Tegenaria domestica, is a species of spider that has been a common inhabitant of human dwellings for centuries. This spider, also known as the House Funnel Weaver, is recognized by its distinctive funnel-shaped web and its ability to thrive in a variety of environments. The Barn Funnel Weaver's adaptability and resilience have made it a successful species, with a wide distribution across the globe, including North America, Europe, and parts of Asia.
Physical Characteristics and Behavior
The Barn Funnel Weaver is a medium-sized spider, with a body length that typically ranges from 10 to 14 millimeters. It has a brown or grayish-brown coloration, with distinctive longitudinal stripes on its abdomen. The spider’s legs are long and slender, allowing it to move quickly and efficiently. One of the most notable features of the Barn Funnel Weaver is its funnel-shaped web, which it uses to capture prey and protect itself from predators. The web is typically constructed in a corner or against a surface, and is characterized by a narrow, funnel-shaped entrance that leads to a wider, more complex network of threads.
Habitat and Distribution
The Barn Funnel Weaver is a highly adaptable species that can be found in a wide range of habitats, including barns, houses, gardens, and forests. It is commonly found in dark, undisturbed areas such as basements, crawl spaces, and woodpiles, where it can feed on insects and other small arthropods. The spider is also known to inhabit outdoor areas, such as gardens and meadows, where it can be found in vegetation and under rocks. The Barn Funnel Weaver’s distribution is widespread, and it can be found on every continent except Antarctica.

Life Cycle and Reproduction
The Barn Funnel Weaver’s life cycle typically consists of three stages: egg, spiderling, and adult. The female spider lays its eggs in a protective sac, which is usually attached to a surface or hidden in a web. The eggs hatch into spiderlings, which are small, immature spiders that resemble adults. The spiderlings go through a series of molts, or shedding of their skin, as they grow and develop. The adult spider is the final stage of development, and is characterized by its fully formed body and reproductive organs.
Predators and Defense Mechanisms
The Barn Funnel Weaver has a number of predators, including other spiders, insects, and small vertebrates. The spider’s primary defense mechanism is its web, which it uses to capture prey and protect itself from predators. The spider is also able to release a foul-tasting fluid from its abdomen, which deters predators and helps to protect it from harm. In addition, the Barn Funnel Weaver is able to vibrate its web to scare away predators, and can also use its speed and agility to escape from danger.
