The Barn Funnel Weaver, also known as Tegenaria domestica, is a species of spider that is commonly found in homes and barns throughout the world. These spiders are known for their distinctive funnel-shaped webs, which they use to catch prey and protect themselves from predators. Despite their fearsome appearance, Barn Funnel Weavers are generally harmless to humans and can actually be quite beneficial to have around, as they help to control pest populations. In this article, we will explore five interesting facts about Barn Funnel Weavers, including their habitat, behavior, and unique characteristics.
Key Points
- The Barn Funnel Weaver is a species of spider that is commonly found in homes and barns throughout the world.
- These spiders are known for their distinctive funnel-shaped webs, which they use to catch prey and protect themselves from predators.
- Barn Funnel Weavers are generally harmless to humans and can actually be quite beneficial to have around, as they help to control pest populations.
- The Barn Funnel Weaver is a nocturnal species, meaning it is most active at night, and it uses its web to catch prey such as flies, mosquitoes, and other small insects.
- Barn Funnel Weavers are able to survive for several months without food or water, making them a highly resilient species.
Habitat and Distribution
Barn Funnel Weavers are found on every continent except Antarctica, and they are most commonly found in dark, undisturbed areas such as barns, sheds, and basements. They are also found in homes, particularly in areas with high humidity and moisture, such as bathrooms and kitchens. These spiders are able to thrive in a wide range of environments, from tropical to temperate climates, and they are often found in areas with an abundance of insects and other small animals.
Behavior and Diet
Barn Funnel Weavers are nocturnal, meaning they are most active at night, and they use their web to catch prey such as flies, mosquitoes, and other small insects. They are also known to eat other spiders, including other funnel weavers, and they will even scavenge for dead insects and other small animals. The Barn Funnel Weaver’s web is a distinctive funnel shape, with a narrow entrance that leads to a wider, more spacious area where the spider waits for prey. The web is made of silk threads that are produced by the spider’s spinnerets, and it is incredibly sticky, making it difficult for prey to escape once they are caught.
| Characteristics | Description |
|---|---|
| Body length | Up to 10 mm |
| Leg span | Up to 20 mm |
| Web shape | Funnel-shaped |
| Diet | Flies, mosquitoes, other small insects |
| Habitat | Dark, undisturbed areas such as barns, sheds, and basements |
Reproduction and Life Cycle
Barn Funnel Weavers reproduce by laying eggs, which are typically white or yellowish in color and are shaped like a sphere. The female spider will lay hundreds of eggs at a time, which will hatch into tiny spiders after several weeks. The young spiders will then disperse and start their own webs, beginning the cycle again. Barn Funnel Weavers can live for up to two years in captivity, although their average lifespan in the wild is typically much shorter, ranging from several months to a year.
Defenses and Predators
Barn Funnel Weavers have several defenses that help protect them from predators, including their web, which is incredibly sticky and difficult to escape from. They are also able to vibrate their web to scare off predators, and they will even release a foul-tasting fluid to deter them. Despite these defenses, Barn Funnel Weavers still have several predators, including birds, lizards, and other spiders. They are also preyed upon by wasps and flies, which will often parasitize their eggs or young.
