Over 40,000 species of spiders have been identified, and many of these creatures look alike. Most people are at least aware of black widows, brown recluses, and wolf spiders since they are large and frightening. That makes it easy to see one spider and confuse it for another. Today, we’re going to look at the parson spider vs wolf spider and show you how they are unique despite looking somewhat similar. By the time we’ve finished, you’ll know several different ways to tell these creatures apart from each other.

The 5 Key Differences Between a Parson Spider vs Wolf Spider
The greatest differences between a parson spider and a wolf spider can be found in their size and markings. Wolf spiders are larger than parson spiders because they have bodies that measure between 1/4 inch and 1 3/8 inches long while having a legspan of 2 to 4 inches while parson spiders have bodies that measure 1/4 inch to 1/2 inch long while having a total legspan of up to 3/4 of an inch.
The parson spider is known for its white abdomen marking that resembles a cravat, a type of neckband worn by clergy in the past. Generally, wolf spiders have light brown, gray, or darker bodies that have two dark bands running from their eyes to the back of their cephalothorax with a light band between them along with a dark marking in the center of their abdomen.
Of course, wolf spiders can have many other different markings because the Lycosidae family is so large. These differences can help you tell the two spiders apart at a glance, but several other differences can be found between these creatures.
Parson Spider vs Wolf Spider: Size
Wolf spiders are larger than parson spiders. The largest wolf spiders have a total legspan of between 2 and 4 inches, far larger than the 3/4-inch legspan of the parson spider. Furthermore, the body size of the wolf spider is much larger than the parson spider.
A wolf spider’s body can measure between 1/4 inch to 1 3/8 inch, though the latter is a size seen only in females. Parson spiders can measure between 1/4 inch to 1/2 inch in body size. Thus, if you see a spider that is larger than an inch, it’s more likely a wolf spider than a parson spider.
Parson Spider vs Wolf Spider: Markings
Parson spiders have a very distinct abdominal marking compared to wolf spiders. When you see a parson spider’s abdomen, you’ll see a light-colored, often white, marking that resembles a cravat, a type of neckband that was once worn by clergymen. That is the source of the “parson” in the parson spider’s name.
Parson spiders also have a light-colored band running down their cephalothorax, and that makes people confuse them for wolf spiders.
Wolf spiders come in many different colors and have some unique markings between species. Generally speaking, though, you will find that wolf spiders have two bands of color that start in the front of the cephalothorax, run over their eyes, and go toward the abdomen.
Between those bands is a light-colored section. The outside of those dark bands is also light in color. The abdomen of a wolf spider can have many appearances, but it’s not unusual to see a dark band of color running the length of the abdomen. Some species have a mottled abdomen, though.
Parson Spider vs Wolf Spider: Eye Arrangement
Both parson spiders and wolf spiders have eight eyes arranged in three rows. However, the wolf spider has two large eyes on top, two medium eyes in the middle, and four small eyes on the bottom. Meanwhile, the parson spider has two large eyes on top, four medium eyes in the middle, and two small eyes on the bottom.
You probably won’t get close enough to these spiders to see their eyes, but it can help you tell them apart.
Parson Spider vs Wolf Spider: Morphology
Parson spiders and wolf spiders have some unique elements of their morphology even though they are both hairy spiders. For example, parson spiders have large, obvious spinnerets at the end of their abdomens, but wolf spiders do not. Wolf spiders have three large tarsal claws on the end of their feet, but parson spiders do not.
Lastly, although it’s not a morphological trait, the presence of young on the wolf spider sets it apart from many other types. Wolf spiders will carry an egg sac on their abdomens, and then they will carry the hatchlings on their backs for several days. Parson spiders are not known for doing that.
Between the size of the spiders’ bodies and the slight morphological differences, it’s easy to differentiate these spiders.
Parson Spider vs Wolf Spider: Species
Lastly, the parson spider and wolf spider are different species, and the two spiders are from different families. The wolf spider belongs to the Lycosidae family, but the parson spider belongs to the Gnaphosidae family.
The eastern parson spider’s species is Herpyllus ecclesiasticus. A good representative of the wolf spider species is the Hogna carolinensis, or the Carolina wolf spider.
All told, the wolf spider and the parson spider are very unique creatures. They can resemble one another at a glance due to the light coloration running down the middle of their bodies. However, morphological elements, coloration, size, and eye arrangement are easy ways to tell them apart.
