A. Common Spider Species

Here are some of the most commonly encountered spider species:

1. Black Widow Spider

The black widow spider is easily recognizable by its shiny black body and distinctive red hourglass-shaped marking on its abdomen. These spiders are known for their potent neurotoxic venom, which can cause severe symptoms in humans if bitten.

a. Physical Characteristics

The female black widow is larger and more venomous than the male, measuring about 1.5 inches in length. They have round, bulbous abdomens and long, slender legs.

b. Habitat and Distribution

Black widows prefer dark, secluded areas such as woodpiles, sheds, and garages. They can be found in many regions across North America.

Black widows are reclusive and only bite when provoked. Their bites can cause symptoms such as severe pain, muscle cramps, and nausea, particularly in vulnerable individuals such as the elderly or young children.

2. Brown Recluse Spider

The brown recluse, also known as the violin spider, is identifiable by the violin-shaped marking on its cephalothorax. Like the black widow, its venom can cause serious health issues.

a. Physical Appearance and Markings

Brown recluse spiders are light to medium brown in color and have a violin-shaped marking on their backs.

b. Typical Habitats

These spiders prefer undisturbed areas such as closets, attics, and basements.

House spiders are typically small and brown, with distinctive chevron markings on their abdomens.

b. Common Habitats

Cellar spiders are often found in dark, damp areas such as basements and crawl spaces.
