In this guide, you will learn about the spiders found in Massachusetts, how to identify them, and what makes them unique.

Introduction: Common Massachusetts Spider Species

Spiders are an abundant species in Massachusetts. There are many different species of spiders that can be found throughout the state. Some of the most common spider species found in Massachusetts include black widows, wolf spiders, yellow sac spiders, and brown recluses.

Black Widows

Black widows are easily identifiable due to their red hourglass shape found on their abdomen. It is important to note that while black widows are dangerous, they are relatively rare in Massachusetts. Black widows are shy and tend to be found in dark, undisturbed places like garages, closets, basements, and crawl spaces.

Wolf Spiders

Wolf spiders can often be found in gardens, yards, and even residential homes. They range in size, usually between 0.125 inches and 1.25 inches in length. Wolf spiders are dark brown and brown-gray in color. They are cautious, solitary hunters that like to stay near the ground.

Yellow Sac Spiders

These spiders are identifiable by their yellow-orange coloration and small size (usually less than 0.75 inches in body length). Yellow sac spiders are often found inside homes, especially those with dark, undisturbed areas. They are curious and territorial, often hiding in tight spaces.

Brown Recluses

Brown recluse spiders are perhaps the most dangerous spider found in Massachusetts. While they are relatively rare, they are easily identifiable by their violin-shaped marking on their abdomens. They tend to be found in dark, undisturbed places like garages, closets, basements, and crawl spaces.

Identifying Spider Species

While it can be difficult for a layperson to identify the species of a spider, there are some key elements to look for. The shape of the legs, web type, and size are all important aspects to look for when trying to accurately identify a spider.

Spider Leg and Body Shape

The shape of the spider’s legs and body is a key element of spider identification. Black widows tend to have long, spindly legs and a globular shape to their bodies. Wolf spiders have shorter legs with a larger body. Yellow sac spiders tend to be small and round with short legs. Finally, brown recluses have thin, long legs and a small oval body.

Web Types

Most spiders create webs, though some species are ground-dwelling and do not make webs. Black widow webs are usually haphazard and messy, often with a funnel shape towards the center. Wolf spider webs are loose and do not typically have a defined shape, tending to look more like a pile of webbing than a well-structured web. Yellow sac spider webs tend to be web-like structures, often in a flat sheet or tube shape. Finally, brown recluse webs tend to be quite messy and often include a funnel shape.


The size of a spider can be an important clue when trying to identify it. Black widows and wolf spiders are typically between 0.25 and 1.25 inches in length. Yellow sac spiders are usually smaller than 0.75 inches in length, while brown recluses can range between 0.2 and 0.5 inches in length.
