The Furrow Spider: A Pest You Don’t Want in Your Home

Hi there! I’m the Furrow spider, and I’m here to tell you all about my life in the fields. I weave my webs in the furrows between the crops, and I’m always on the lookout for tasty insects to eat.

I know that some people are afraid of spiders, but I promise that I’m harmless. In fact, I’m actually quite helpful to farmers. By eating pests like aphids and moths, I help keep the crops healthy.

So next time you’re out in the fields, keep an eye out for me! And if you’re not afraid of spiders, maybe we can even be friends.


What is a furrow spider?

The Furrow Spider


Furrow spiders are so named for the deep, parallel furrows on their carapace. The carapace (upper surface of the cephalothorax) is hard and glossy, and may be brightly colored. The abdomen (lower body surface) of both sexes is striped horizontally with alternating bands of light and dark colors. Females are larger than males and may reach a total body length (including legs) of up to 18 mm. Males never exceed 12 mm in body length.


Where do furrow spiders live?

Furrow spiders are found in North America, Europe, and parts of Asia. In the United States, they are most commonly found in the southern states.


What do furrow spiders look like?

Furrow spiders are brown, small to medium-sized spiders that have distinctive patterns on their abdomens. The patterns can be various shapes, but they are always arranged in a series of parallel lines or “furrows.” These unique markings help to camouflage the spiders when they are hunting for prey.


What do furrow spiders eat?

Furrow spiders are generalist predators, which means they will eat just about anything they can catch. Their diet consists of a wide variety of insects, including flies, moths, beetles, and wasps. They will also eat other spiders, if they are small enough to be overpowered. Occasionally, furrow spiders will also eat small vertebrates, such as lizards and frogs.


How do furrow spiders hunt?

Furrow spiders build their webs in dry, sheltered areas such as crevices in rocks, under the eaves of buildings, or in dense vegetation. The webs are model tensile structures, with lines of greatest stress running along the diagonals of the web. The silk is very strong and is used by the spider to wrap prey securely before biting it and injecting venom.

The web serves as both a trap and a snare. The spider sits in the center of its web with its legs outstretched, waiting for an insect to blunder in. When an insect brushes against one of the strands of silk, the vibration is transmitted along the line to the spider. The spider then rushes over to subdue its prey with a rapid series of bites that injects venom.


What is the life cycle of a furrow spider?


Furrow spiders are found in many different habitats around the world. They build their webs in grassy areas, Hedgerows, and among crops such as corn, wheat, and oats. The spider gets its name from the furrow-like shape of the web it builds.

Furrow spiders are nocturnal predators that hunt their prey at night. During the day, they rest in the center of their web or in a nearby hiding place.

The life cycle of a furrow spider begins with an egg sac that contains anywhere from 50 to 200 eggs. After about two weeks, the eggs hatch, and the spiderlings begin to spin their own webs. They molt (shed their skin) several times as they grow, reaching adulthood in about two months.

Furrow spiders mate in late summer or early fall. After mating, the female lays her eggs and dies. The egg sacs overwinter in grasses or other vegetation and hatch the following spring.


What threats do furrow spiders face?

Furrow spiders are found throughout most of the United States. They are common in agricultural areas and often build their webs in furrows between rows of crops. These spiders are not considered to be dangerously venomous to humans, but their bites can cause reactions in some people.

Although furrow spiders are not considered to be a major threat to crops or humans, there are some potential dangers that they pose. Their bites can cause reactions in some people, and their webs can sometimes interfere with the operations of agricultural machinery. In addition, these spiders may compete with other insect-eating animals for food resources.
