Appearance: Wolf spiders are usually, brown, grey, black or tan, with dark markings (usually stripes).

The brown widow spider, Latrodectus geometricus, is not native to the United States. For decades, it lived only in peninsular Florida in the U.S. but in the first decade of the 21st century, it spread remarkably quickly, is now found from Texas to South Carolina and is well established in the urban areas of Los Angeles, San Diego and surrounding suburbs. In the western United States, accurate identification of this spider can be difficult. The brown widow is a tan spider with a series of white stripes. Unfortunately, immatures of the native black widow spider, Latrodectus hesperus, also are tan with white stripes and are frequently mistaken for brown widows. There is TREMENDOUS variation for both of these species as they grow from babies to adults. In order to master identifying them, many specimens need to be examined. Below is a pictorial comparison of the two species with ways to differentiate between them. Many people send in orb weavers orb weavers of the genera Neoscona and Araneus. Orb weavers have spines on thier legs, widow spiders have no spines. Please check the internet to identify orb weavers to reduce the chance of misidentification.

Of secondary usefulness, the central longitudinal stripe on the top part of the abdomen can likewise help differentiate species. Compare that to the immature western black widow and you see that the light colored stripe is more of a straight line or may be flattened a little at the top.

Also notice that the forwardmost dot in the brown widow is isolated from the rest of the stripe and is about twice as wide as long. The same place that would have the dot on the immature western black widow is continuous with the stripe (at least in the early stages of life). As western black widows mature, they develop more dark pigment in the background area, the stripes start to break up into nebulous isolated patches and eventually disappear as the spider continues to molt and adds darker pigment on its way to turning completely black.

Sometimes the adult female black widow retains a portion of the continuous line in the front part of the abdomen. Notice that the abdomen isnt as shiny and reflective as that of a black widow and there are traces of brown coloration.

Spotting a spider in your immediate vicinity can be a little intense, especially if you have a major fear of the creepy crawlers. And, when one shows up in your home, it can be downright freaky. Unfortunately, you might start to notice more spiders inside your basement, attic, bathroom, and general living spaces now that its getting cooler out.

These are nomadic spiders that dont spin webs to catch their preythey hunt them down, says Howard Russell , an entomologist at Michigan State University. Where youll find them: They can hide in mailboxes or garages, and they like corners, edges, and tall grass, Russell says.

Where youll find them: The brown recluse likes to hang out in undisturbed corners of homes, in sheds, and in basements or cellars. Many bites occur because the spider is hiding in folded towels and sheets, underneath a pile of clothes on the floor, or in shoes in a closet, Potzler says. If you live in an area where brown recluse is common, its a good idea to shake out your clothes and shoes, or wear gloves if you are working in your shed or garage.

What they look like: Youre probably pretty familiar with this one, but just in case: It has one round body part and very thin, long legs coming off of it. They dont build webs, but theyre what Potzler calls active daytime hunters so you can spot them at any time. Its not common for these spiders to bite but there have been some reports of hospitalizations for individuals who have compromised immune systems or pre-existing health conditions, Potzler says.

The majority of Kentucky’s spiders are harmless to humans, even when they enter our living environments. This chart is designed to help with quick identification of spiders that are commonly encountered in homes, buildings, yards, and other urban environments. Click on the spider to read more about it.

Features: Dark violin-shaped mark on back, with the neck of the violin pointing toward the rear (abdomen) of the spider. This feature is consistent in adult brown recluses, but can be hard to see and is less obvious in younger spiders.

They tend to occur in hidden locations indoors and outdoors: piles of cardboard or paper, stacks of cut wood, and wall-voids of buildings. Features: Prominent hind spinnerets: these are two, small, finger-like projections on the end of the grass spider‘s abdomen (used to spin the web). Notes: Grass spiders are very common in Kentucky lawns where they build large, funnel-shaped webs.

Fishing Spider Size: A little larger than a U.S. silver dollar, with legs outstretched. Features: Very large brown spiders; sometimes seen running on the ground or sitting motionless on tree trunks. Notes: Fishing spiders are common near streams and wooded areas in Kentucky, and they sometimes wander into nearby homes.

Color: Brown and tan highlighted with dark brown patterns Features: Spherical abdomen; almost always encountered in its compact, messy cobweb Notes: The American House Spider is one of the most commonly encountered spiders in Kentucky and is found in many homes and buildings. Unlike brown recluses, though, house spiders are almost never found outside of their webs. Color: Tan legs and head, yellow abdomen Features: Low, flat spider; does not build a web Notes: The yellow sac spider is commonly found in homes and it is often mistaken for the brown recluse because it is similar in shape, but the yellow sac spider lacks the “fiddle” pattern of the brown recluse.

The bite of a yellow sac spider can be painful, but it is not medically significant except to allergic individuals. Notes: Orb weavers are commonly found on porches and gardens in Kentucky, especially in late summer. The Yellow-and-black Argiope (pictured below, top left), one of the largest spiders in Kentucky, is a type of orb weaver.

Features: Jumping spiders have distinctive, large eyes and a “flat faced” look. Features: Woodlouse hunters are distinguished by their very large fangs and low, flat shape. Notes: Woodlouse hunters are often found outdoors under rocks and logs near buildings where they hunt for woodlice (a.k.a.

Because these spiders are brownish in color and similar in size, they are occasionally mistaken for brown recluses. Like most Kentucky spiders though, the bites of woodlouse hunters are harmless except to allergic individuals, despite their large fangs. Some are brown or tan, but most common species are bright white or vivid “neon” green or yellow.

Features: Crab spiders are low and flat and their front two pairs of legs are very long. Notes: Crab spiders are very common in Kentucky flowers (where they hunt for bees), but they sometimes wander into homes. Purseweb spiders are larger than black widows, though, and lack red markings.
