8/11/2023 0 Comments Grass spider predators![]() They can be somewhat frightening due to their size and ability to move extremely fast. Grass spiders also have two prominent spinnerets, which are typically not as noticeable on other spider species. They have eight eyes arranged in three rows with two on top, four in the middle, and two on the bottom. Grass spiders have dark bands on their legs as well. Different areas of their bodies have darker markings, such as two stripes down the length of their cephalothorax. They are typically brownish to grayish and have hair on their legs and other parts of their bodies. If size matters to you where spiders are concerned, you will most likely not appreciate the presence of grass spiders that grow between 1/5-inch to 3/4-inch, not including their legs. When males reach sexual maturity, they set out in search of females and die shortly after mating several times. They spend most of their time capturing and consuming prey in preparation for mating and producing eggs. Females build their web and rarely move unless threatened or there’s a lack of prey. They skip the ritualistic wrapping of their prey in webbing like some of the grass spiders’ relatives do. When grass spiders capture prey, they carry it to their funnel and consume it immediately. This is thought to be accidental due to the proximity in which they live and the result of them unintentionally wandering onto a neighboring web. Their primary source of food is insects, but they will cannibalize other grass spiders. ![]() The spider then rapidly runs out to attack before its victim can make a getaway. Its web works as an alarm system of vibrations, letting the grass spider know that some unfortunate soul has stumbled upon its hunting grounds. The grass spider makes up for its non-adhesive webbing with speed, as it can move extremely fast to capture its prey. This may seem like a disadvantage, but it’s not. Unlike other spiders that spin webs to capture prey, the grass spider’s web has no adhesive properties. Their webs are a flat sheet with a funnel-like shelter at the edge where the spider lies in wait for an unfortunate victim. Grass spiders are scientifically classified as the family of Agelenidae, and they are funnel weavers. Discovering their behaviors can help you keep them out of your house and relatively sparse on your property so that you can provide a safe environment for your family and pets. ![]() They can and will bite if threatened, and they become a nuisance when they have infested your property and home. Grass spiders are a relatively large spider and can be very intimidating. This doesn’t mean that spiders are always good to have around, especially when they have invaded your home. They keep insect populations in check, and they also provide an ample supply of food for predators higher up on the food chain. When found in their natural habitats, spiders positively contribute to the environment.
