This lesson aims to teach vocabulary to English learners by summarizing some of the most common types of spiders, their distinguishing characteristics, and where you are likely to encounter them.
Spiders are everywhere, from the ceilings of our houses to outdoor spaces. They come in many colors, such as brown, red, gray, and white. Although spiders may look eerie and often cause fear, most are non-venomous and do not bite humans unless provoked.
Types of Spiders
- Black Widow Spider
- Hobo Spider
- Brazilian Wandering Spider
- Brown Recluse Spider
- Wolf Spider
- American House Spider
- Orb-Weaver Spider
- Daddy Longlegs (Cellar Spider)
Venomous Spiders
Black Widow Spider
This spider is feared worldwide because of its potent venom, which can cause muscle pain and breathing difficulties due to paralysis of the respiratory muscles. Black widow spiders are mainly found in the Americas, especially North America, but related species of the Latrodectus genus also occur in parts of Europe, Africa, Asia, and Australia, where the redback spider is a close relative.
The female has a shiny black abdomen with a distinctive red hourglass marking. After mating, the female may feed on the male to gain nourishment for her unborn spiderlings. The male is seldom seen and is much smaller, measuring about one-quarter of the female’s body size.
Hobo Spider
This species gets its name from its frequent sightings along railroad tracks. It is usually brown and has very hairy legs and body. Hobo spiders are found mostly in the northwestern parts of the United States.
Their bites are non-necrotic, and symptoms from the venom usually subside within 24 hours.
Brown Recluse Spiders
Brown recluse spiders typically measure about 0.25 to 0.75 inches in body length. Brown recluse spiders are most commonly found in the central and southern United States, especially in states such as Arkansas, Missouri, Oklahoma, Tennessee, Mississippi, Kansas, and Alabama.
They are known for the violin-shaped marking on their bodies and have six eyes arranged in three pairs.
Brazilian Wandering Spiders
These spiders are also referred to as banana spiders because they are commonly found in banana plants. They can inject venom that affects the victim’s central nervous system, causing severe pain and other systemic effects.
Non-Venomous Spiders
Wolf Spiders
Referred to as wolf spiders because their hunting skills resemble those of a wolf, these spiders actively hunt instead of using webs. They are usually brown and have excellent vision.
They have eight eyes arranged in three rows, which helps them detect movement easily.
American House Spider
These spiders are mostly gray and have round abdomens. They commonly build their webs in dark, quiet, and concealed corners of buildings and homes.
Orb-Weaver Spider
Orb-weaver spiders are unique because they build and tear down large circular webs daily to trap insects. They can grow up to 2–3 cm in size and are usually gray or brown.
Daddy Longlegs (Cellar Spider)
This is one of the most common spider species found worldwide. It usually builds messy webs in corners, ceilings, and basements.
They are easily recognized by their extremely long, thin legs and small bodies.
Key takeaway
Most spider bites are rarely fatal because spider venom is primarily designed to immobilize small prey such as insects. If you live in an area prone to spider encounters or plan to travel to a spider-infested region, owning a spider identification book can be a worthwhile investment. It helps you distinguish between venomous and non-venomous spiders and reduces unnecessary fear.
