The biggest differences between a fishing spider and a wolf spider are their colors, leg length, and eyes even though most people probably don’t want to get too close to their faces to see their eyes at first.

Although fishing spiders and wolf spiders can be brown and gray with banded leg colors, wolf spiders will often have a thick distinct stripe running down its body. That stripe can be a lighter color than the rest of the wolf spider, or it can be darker. The same is not found on a fishing spider.

Fishing spiders have longer legs than wolf spiders because of their need to walk on water. Lastly, fishing spiders have eight eyes in two horizontal rows with four eyes in each, but wolf spiders have eight eyes in three rows, with two eyes, then two larger eyes, then four small eyes. Wolf spiders’ eyes are very large compared with other spiders and helps them have great vision.

These key differences can help you identify the spiders quickly and easily.

Fishing Spider vs Wolf Spider: Size

The wolf spider can grow larger than the average fishing spider. Granted, the Dolomedes (fishing spider family) can vary in length, they average about 0.35 inches to 1 inch in body length without the addition of its leg length. Wolf spiders measure between 0.25 inches to 1.2 inch for their body length

When you factor in the leg length, fishing spiders are about the same size or longer than wolf spiders.

Fishing spiders are found near water sources such as streams and ponds. Wolf spiders are most often found in dark recesses such as tree hollows or at the entry area of insect burrows where they can easily feed.

Both spiders sometimes become trapped indoors when they chase prey into a house, but it’s more likely that a wolf spider moves indoors and hunts in basements and other dark areas.

The fishing spider hunts by using the hairs on its legs to detect prey, but wolf spiders use their eyes to find prey and their powerful legs to chase them down. Both creatures have trichobothria, the fine hairs on their legs that sense the world around them, but fishing spiders use them as their primary means of finding prey.

All fishing spiders and wolf spiders have eight eyes, but they are arranged differently. Fishing spiders have eight eyes spread across two rows, four on top and four on the bottom.

Wolf spiders’ eyes are arranged in three horizontal rows and centered on the head. They contain two small eyes, two large eyes, and then another four eyes on the bottom. Wolf spiders’ eyes are very visible to humans since they are the primary means that wolf spiders use to identify their prey.

Fishing spiders and wolf spiders look somewhat alike, but you can tell them apart by learning their most obvious differences. In this case, look at the spiders’ size, location, colors, and leg length. These factors are the easiest and safest way to tell the two creatures apart.

Remember that neither the fishing spider nor the wolf spider wishes to be in your home most of the time. A wolf spider might have wandered into your home in search of food and then became trapped.

They’re excellent at killing pests for the short time they’ll stay in your home, and they pose a very small threat to humans since they would prefer to avoid being seen by humans at all. Instead of killing them, it’s a good idea to leave these spiders alone unless you have small children or pets that they could harm.
