Body of a Spider
Spiders are classified as arachnids. The front part of a spider’s body is called the cephalothorax. The back part of a spider’s body is called the abdomen. There are finger-like appendages attached to the abdomen known as spinnerets. These structures are silk-spinning organs and are often used for identifying the spider.
Common Spiders Found in Maryland
1. Jumping Spiders
Scientific name: Phidippus Clarus
In the arachnid class, the jumping spiders can be considered as the true casanovas. They move in short, rapid runs or jumps. They are brightly colored and present some elaborate songs and dances to attract their mate. These spiders tend to have a large pair of eyes mounted on the front of a relatively flat face. In comparison, the other three pairs of eyes are relatively small.
These spiders in Maryland are adept hunters. They are frequently found around the window in search of prey such as flies and small insects. Jumping spiders are usually black and hairy. They may possess white or red dots. These spiders can be as large as 1/3 inch long. Jumping spiders do not appear in large numbers generally and can be removed individually.
2. Black Widow Spiders
Scientific name: Latrodectus mactans
The black widow is one of the most common spiders in Maryland and is not usually found indoors. The spiders are commonly found in basement windows, wells, tool sheds, beneath lawn benches or porches, and water meters. They can be inside objects such as baskets, boxes, flower pots, or other items stored outside for a period of time.
The Black widow female spider in Maryland is about 1/2 inch long, jet black with a bright red hourglass shape on the belly. There may be a red mark on the top of the abdomen and at the tip, which becomes easily visible when she hangs upside down on the web.
The male Black widow spiders have a more vibrant pattern on their abdomen consisting of many red and white spots.
The bite of a black widow is very dangerous. Black widow bites feel like a minor pinprick, but dull pains will soon develop in the bite area. The affected area usually begins to cramp, and other symptoms such as nausea, sweating, and vomiting may occur.
There are no other spiders in Maryland that look like the Black widow, nor are any as poisonous. These spiders are not aggressive, but when touched or pressed, it bites instinctively. It is more dangerous to children than adults.
It is often advised to wear gloves and pay attention while working around areas where black widows may be present. Black widow bites are sharp and painful, and the victim should immediately run to the doctor for treatment.
3. Wolf Spiders
Scientific name : Rabidosa rabida
Wolf spiders are one of the most intimidating spiders in Maryland. These spiders do not construct webs. They can move fast and are active hunters. Their good vision helps them in hunting down the prey day and night. Wolf spiders are hairy, lone wolves that can demonstrate quite aggressive behavior. They help eliminate other pests. They do not attack humans even if they run across one’s hand or foot. But if someone tries to handle or find them, they can give a sharp bite.
These spiders in Maryland can range from black and white color to earthly tones. Some wolf spiders can have a quite large and frightening appearance. Their size can vary from 1/4 inch to 11/2 inches in body length and 3 inches with a leg span. Wolf spiders mostly come indoors during the fall and are usually found in the basement. The best way to keep them outdoors is exclusion.
4. Crab Spiders
Crab spiders have their legs projecting from their sides, giving them the appearance of a crab. They can be bright white, yellow, or reddish in color. They are not active hunters and use the art of camouflage to snag their prey. They sit waiting on flowers and leaves, ready to attack their prey that comes along. The goldenrod crab spider is a bright yellow color, which helps it to blend in with the yellow petals of goldenrods.
Crab spiders are beneficial for the environment as they eat many insect pests found in gardens and flower beds. Crab spiders are not known to bite humans, but some scientists believe that the venom of many crab spiders is more potent than most spiders. It helps them to subdue prey such as bees.
5. Cobweb Spiders
Cobweb Spiders are common spiders in Maryland that enter the household when they are small. They build irregular webs in areas like the corners of rooms or windows where insects usually fly or rest. The active webs of the cobweb spiders remain relatively inconspicuous. But when they leave their web or die, the web becomes covered in dust and becomes visible.
6. Orb Weavers – Garden Spiders
They are more than 2,500 species of orb weavers in the United States. Garden spiders like the black and yellow Argiope aurantia are some orb-weaving spiders. Argiope aurantia is one of the most recognizable ones. They are most often seen in late summer and autumn. The spiders in Maryland are large and mark with black and yellow or orange.
Orb weavers have poor vision. They produce a flat, neat, and classic spider web with a circular grid to capture prey.

These spiders are great at catching all types of insects, including stink bugs and butterflies that may stumble into their webs.
