Spiders, fascinating members of the ‘Arachnids’ group, boast a unique anatomy with two body segments and eight legs, distinct from the six-legged insects.
Many are unaware of this difference, mistakenly categorizing spiders as insects. Understanding these creatures can be enlightening, especially considering their role in ecosystem balance through pest control.
However, their presence can be unnerving, particularly for those suffering from Arachnophobia, the most prevalent phobia today. To alleviate fears, knowledge is key.
This guide, complete with a spider identification chart, aims to educate and intrigue, providing insight into the various spider types.
Types of Spiders
1. Tarantula
Tarantulas, often perceived as large and intimidating, are diverse in size and behavior. While some species can grow large, with females typically larger than males, the largest tarantulas reach about 11 inches in leg span.
Their appearance, characterized by a hairy body, varies in color from browns and blacks to more vibrant hues in certain species. Contrary to popular belief, tarantulas do not use webs to capture prey.
Instead, they are active hunters, using their size and strength. Despite their fearsome reputation, most tarantulas are not dangerous to humans. Their venom is typically not harmful beyond a bee sting’s pain level.
Some species, known for their docile nature, are even popular in the pet trade. However, their behavior can vary, and they might display defensive postures if threatened.
2. Brown Recluse Spider
The Brown Recluse Spider, also known as the Violin Spider due to a violin-shaped mark on its back, typically has a light to dark brown coloration.
This species is distinct from many other spiders, possessing only six eyes instead of eight. Brown Recluse Spiders have a relatively smooth appearance.
These spiders are smaller, typically between 0.24 to 0.79 inches. They are often found in undisturbed, secluded areas like storerooms, garages, and basements.
While their venom can cause significant medical issues in humans, they are not aggressive and bite only in self-defense. Brown Recluse Spiders use non-sticky webs primarily for retreat rather than capturing prey.
3. Camel Spider
Camel Spiders, also known as Wind Scorpions or Sun Spiders, are not true spiders or scorpions but belong to the order Solifugae.
They are known for their large size, with some reaching up to 6 inches, but they are typically smaller. These creatures have a unique appearance with large, prominent jaws.
They do not possess enlarged eyes but have a pair of median eyes and no lateral eyes. Their coloration ranges from tan to dark brown, allowing them to blend into their desert environments.
Camel Spiders are solitary and nocturnal, often found hiding under rocks or in sandy areas. They are known for their remarkable speed, moving up to 10 mph, and they primarily feed on various small animals, including insects and small vertebrates.
4. Black Widow Spider
The Black Widow Spider is recognized for its venom, particularly potent in females, and can cause significant pain and discomfort.
Females are easily identified by their glossy black bodies with a distinctive red hourglass-shaped mark on the underside of their abdomen. In contrast, males are smaller, lighter in color, and less venomous.
Black Widows are found predominantly in warmer regions, including parts of North America and Mexico. They prefer secluded spaces and are known to be more active in warmer temperatures.
Their diet primarily consists of insects, which they capture using their webs. While their venom is dangerous, fatalities are extremely rare due to the availability of effective antivenoms.
5. Wolf Spider
Wolf spiders are robust and agile hunters, named more for their hunting prowess than their appearance. They have eight individual eyes arranged in three rows.
Their body size and color vary widely, adapting to different environments. Globally distributed, wolf spiders are commonly found in various habitats, including North Carolina.
Unlike other spiders that spin webs, wolf spiders actively hunt and sometimes dig burrows for shelter, though not all species are burrowers. They primarily feed on insects.
The mating behavior of wolf spiders is unique, with males often performing elaborate courtship rituals to avoid being mistaken as prey by females.
6. Jumping Spiders
The Jumping Spider family, comprising about 5,000 species, represents a significant portion of the spider population, estimated to be around 13% globally.
These spiders are easily recognizable by their unique eye arrangement: four large eyes in a single row, with the pair in the middle particularly prominent, contributing to their excellent vision.
Unlike many spiders, Jumping Spiders possess a well-developed internal respiratory system that includes both lungs and a tracheal system.
Known for their remarkable jumping ability, these spiders do not use silk for jumping but for safety lines as they leap.
They are active hunters in various habitats, typically feeding on insects, including forests, grasslands, and mountainous regions.
Their ability to adapt to different environments is key to their survival.
7. Goliath Bird-Eater Spider
The Goliath Bird-Eater, part of the Tarantula family, is one of the largest spiders by mass. Its name is somewhat misleading, as its diet primarily consists of insects and small mammals, not birds.
The “bird-eater” label originated from an observation of one eating a hummingbird, which is uncommon. These spiders, native to the rainforests of South America, are known for their large size, with a leg span reaching up to 11 inches.
They create burrows in the ground, similar to some wolf spiders, but are not typically aggressive towards humans.
Their defensive mechanism includes making hissing sounds by rubbing their legs together. Despite their intimidating appearance, their venom is not lethal to humans.
8. Golden Silk Spider
The Golden Silk Spider, known for its unique golden-hued web, is called the “Giant Wood Spider” or “Banana Spider.” The silk’s color, which ranges from yellow to gold, contributes to the effectiveness of its web in sunlight.
This spider exhibits varied coloration, including shades of red, green, yellow, black, and brown, with females being larger than males.
Commonly found in warmer climates, these spiders have a wide distribution, including regions like Madagascar, Australia, and the United States.
They rely more on their other senses than vision, detecting danger through vibrations. Their diet mainly consists of insects and small animals, and while venomous, they are not typically a threat to humans.
9. Brazilian Wandering Spider
The Brazilian Wandering Spider, often cited as one of the world’s most venomous spiders, is known for its potent venom. It typically grows to about 5 inches in leg span.
Found primarily in South American tropical forests, including Brazil, Peru, and Colombia, this spider is not restricted to jungles and can occasionally be found in populated areas.
It has gained attention for occasionally hiding in shipments of bananas, but this is not its typical habitat. Known for its aggressive behavior when threatened, the Brazilian Wandering Spider is a nocturnal hunter, actively seeking prey rather than using webs.
10. Hobo Spider
The Hobo Spider, commonly considered aggressive, is less dangerous than often portrayed. Their coloring is typically uniform, with a brownish hue and characteristic V-shaped patterns on their abdomen, but they don’t usually have prominent spots.
Originally from Europe, they have spread to various regions, including the Northwestern United States. Their presence in new areas is attributed to human activity, such as transportation and trade.
Contrary to their reputation as fearsome, Hobo Spiders are not commonly encountered in homes, and their venom is not considered a significant medical threat to humans. They create funnel-shaped webs for catching prey like insects.
