Wolf Spider: A Stealthy Hunter of the Arachnid World
A wolf spider is a group of spiders in the Lycosidae family. They are interesting and come in many types. They have adopted most of the world’s eco-systems. There are more than 2,000 kinds of these spiders all over the world, and they live in different places, showing how well they can adapt and handle tough situations.
Wolf spiders are different and interesting. Most of them don’t make intricate webs to catch food. Instead, they hunt down their prey like the famous animal they’re named after. Female wolf spiders carry their babies on their backs. Even though they might seem scary, these spiders help control the number of other insects around.
Identification
You can recognize wolf spiders because they’re hairy and come in colors like orangish-brown, gray, or black, with spots or stripes that help them blend in. Wolf spiders have eight eyes arranged in three rows of different sizes on their head. They also have eight legs like all spiders, and in the front, they have two tiny leg-like things called pedipalps. The regular wolf spider can be small, about half an inch to 2 inches long. Female wolf spiders are usually bigger than males.
Wolf spiders come in different sizes, ranging from 0.24 to 1.2 inches, roughly the size of a coin, and they usually weigh less than an ounce. With legs much longer than their bodies, they seem larger than their actual size. Typically, females are bigger than males.
Scientific Name & Species
The wolf spider, scientifically named Lycosidae from the ancient Greek word for wolf, comprises a vast family with around 124 known genera and over 2,800 species, the exact number depending on classification.
Behavior and Hunting
Although wolf spiders are connected to web-building spiders, they don’t create big webs. However, they use silk for various things, such as making egg sacs. As a result, the silk they produce has a slightly different makeup and strength compared to the silk of web-building spiders. Since they can’t build webs, their way of hunting is more similar to that of large carnivorous animals, like wolves, rather than other spider species.
Wolf spiders are night hunters, spending most of their time on the ground but occasionally climbing trees or vegetation for prey. They rely on keen vision and sensitivity to vibrations for stalking and avoiding predators. Additionally, they communicate through sounds and emitted chemicals.
Wolf spiders display varied behaviors; some are nomadic or territorial. Certain species construct hidden burrows beneath rocks or logs, securing them with debris for safety. These spiders often stick to a specific hunting ground they revisit nightly. In contrast, other wolf spiders are more transient, roaming over large areas in search of food and occasionally venturing into human spaces during colder weather.
During the fall, wolf spiders can become quite common pests in certain regions as they seek refuge from the cooling temperatures, often leading them to venture indoors. In houses, you might spot them near door or window frames, in houseplants, as well as in basements and garages. Despite their presence, these spiders typically avoid people and will likely scuttle away when they sense your footsteps.
What Do Wolf Spiders Eat?
Wolf spiders have a taste for ground-dwelling insects like ants, worms, and insect eggs. Being carnivores, they actively hunt for their food. Despite their size, ranging from one to three inches with legs spread out, wolf spiders have even been spotted eating small frogs and toads. They are opportunistic hunters, mainly targeting insects that don’t fly. Some of their favorite meals include Ants, beetles, earwigs, worms, spiders, roaches, pill bugs, aphids, millipedes, and centipedes.
Lifespan and Life Expectancy
Male wolf spiders typically have a lifespan of around one year, while females can live for several years. After mating, a female wolf spider lays a batch of eggs and wraps them in a silk ball. She attaches this egg sac underneath her abdomen using her spinnerets. Burrowing wolf spiders usually place their egg sacs in their tunnels at night but bring them to the surface during the day for warmth.
When the spiderlings hatch, they climb onto the mother’s back and stay there until they are big enough to venture out on their own. These nurturing behaviors are distinctive and specific to the life cycle of wolf spiders.
Mating and Reproduction
The mating process for wolf spiders comes with risks, as males can be killed and consumed by females after mating. Despite this danger, many males manage to survive and mate again.
Wolf spiders display distinctive parental care behaviors, with females frequently carrying their egg sacs. Once the eggs hatch, the young spiders stay with the female for a few weeks before going their separate ways.
Wolf Spider and Human
Wolf spiders are generally not aggressive and won’t bite unless they feel threatened or provoked. While a wolf spider’s bite is not fatal, it can be quite painful. These spiders usually only bite humans if they are handled or touched, as they tend to avoid people and will run away when humans are nearby.
