    Object1: Black widow spider

    Life styles

    This type of spiders prefer to live in undisturbed areas, such as rock or woodpiles, occupy garages, storage sheds, or crawlspaces, particularly in temperate regions around the world. Black widow can be identified by their round, shiny black bodies and the distinctive red hourglass marking on their underside.

    Physical features

    Black widow bites are rarely fatal, but can be serious and should receive medical attention as soon as possible. Symptoms may include a headache, muscle cramps, and weakness. Female black widow spiders are about 0.5 inches long, to about 1.5 inches long when the legs are spread. Males are about half the female's size, with smaller bodies and longer legs. Both females and males have shiny, globular abdomens and are mostly black and sometimes brown. Like many spiders, the black widow spider eats other arachnids and insects that get caught in their webs.

    Object 2: Brown Widow spider

    Lifestyle

    They can live in a small clear plastic container with a hole in the center of the lid that is stuffed with a piece of cotton.The venom of a brown widow is twice as potent as a black widow, although brown widows release less venom when they bite. Prevent brown widows in your home by tidying up and removing clutter to take away their hiding places, and by keeping your home free from other insects so they have fewer food sources.The brown widow builds its web in secluded, protected sites around homes and in woody vegetation with branches. brown widows are more inclined to spin their webs in places humans congregate, especially under outdoor furniture and around barbecues.

    Physical Features 

    These types of spiders are brown as the name suggests, an easier way to recognize a brown widow is by its egg sac which is covered in small silk spikes. The size of the brown widow is almost between 1 to 1.5 inches, their eating habits are preferred to eat insects inside the home.

    Object3:Brown Recluse

    Life Style

    Brown recluse spiders feed on soft-bodied insects such as crickets, cockroaches, moths and flies. Although it is known for having a violin on its back, the best way to identify a brown recluse is by its eyes — most spiders have eight eyes (two rows of four) but a brown recluse has six eyes (three sets of two). Of course, few people want to find themselves eye to eyes with a spider! Brown recluse venom is poisonous to people, and if you suspect you have been bitten by one, seek medical attention. Symptoms include a blister at the site of a bite, fever, and possible infection.

    Physical Features

    The brown recluse spiders are brown in color and reclusive by nature; their characteristics are preferred to avoid humans and other creatures, spending its time in secluded and undisturbed areas like quiet corners and neglected spaces. The brown recluse spider size is about 6-20 millimeters.

    Object 4: Wolf spider

    lifestyle

    Wolf Spiders are members belong to the family Lycosidae. They are so named because their method of hunting is likely to run down their prey like that of a wolf. They are robust and agile hunters that rely on good eyesight to hunt, typically at night. Wolf Spiders resemble nursery web spiders (family Pisauridae), however, they carry their egg sacs by attaching them to their spinnerets (instead of by means of their jaws and pedipalps).

    Wolf spiders live in all kinds of habitats, anywhere there are insects to eat. They seem to be most common in open habitats like grasslands, and are often found in farm fields and meadows. Most species stay on the ground, but a few climb up onto trees and other plants when hunting. Some wolf spiders hunt along the shores of ponds and marshes, and may even dive into the water to capture prey.

    Physical Features

    Wolf Spiders range from about half an inch to 2 inches in length. They are hairy and typically brown to grey in colour with a distinct Union Jack impression on their backs. The spiders undersides are light grey, cream or black, sometimes salmon pink and have eight eyes arranged in three rows.
