7 COMMON Spiders Found in Uganda! (2024)

What kinds of spiders can you find in Uganda?

Types of spiders in Uganda

Many people are terrified of spiders and find them extremely creepy. This is unfortunate because not only are most spiders completely harmless, they benefit our environment by controlling the insect population. In fact, without spiders, our food supply would be in serious jeopardy.

Before we begin, I want you to know that the list below is just a fraction of the spiders in Uganda. Because of the sheer number of these arachnids, it would be impossible to cover them all. For example, some estimates claim over 50,000 kinds of spiders on the planet (and the list is still growing)!

In today’s article, I did my best to develop a list of spiders you’re most likely to see.

7 common SPIDERS in Uganda!


#1. Hairy Golden Orb-weaving Spider

  • Trichonephila fenestrata

Also known as the Tufted Golden Orb-weaving spider.

Common Uganda spiders

Identifying Characteristics:

  • Their coloring is predominantly yellow with black patterns.
  • The legs are dark brown or black with hairy middle parts (brushes).
  • Females are 20-40 mm (0.8-1.5 in). Males are 5-6 mm (0.19-0.23 in).

Look for this spider in Uganda in wooded areas where they can make their web and catch prey easily.

Hairy Golden Orb-weaving Spiders makes elaborate flat webs of concentric circles and spokes from the center. Their webs can reach up to 1 meter (3 feet) in diameter. The silk has a yellowish color, which serves two functions: in the sun, bees are attracted to the color, and in the shade, it blends in with the surrounding vegetation.

Male Hairy Golden Orb-weaving Spiders have an unusual tactic to survive mating, which is typically dangerous for spiders. During mating, the male sacrifices one of its front legs as a snack for the female. This behavior increases the chances of successful mating while decreasing the chances of the male being eaten by the female. And you think dating is hard for humans!


#2. Brown Widow

  • Latrodectus geometricus

Also known as the brown widow, brown button spider, grey widow, brown, black widow, home button spider, or geometric button spider.

Common spiders found in Uganda

Identifying Characteristics:

  • The coloring is mottled tan and brown with black accent markings. On the sides of the abdomen, there are three diagonal stripes.
  • This species has an hourglass similar to the black widow, but it’s often orange or yellow.
  • The striped legs are usually dark brown or black with light yellow bands.

The Brown Widow employs a neurotoxic venom, causing pain, muscle rigidity, vomiting, and sweating. However, while deadly to their prey, the bites of the Brown Widow are often much less harmful to humans than the infamous Black Widow.

Females create webs in isolated, safe locations near houses and branch-heavy woods. Brown Widows frequently choose empty containers like buckets, planters, mailboxes, and entryway corners. So, checking these places thoroughly before disturbing them is a good idea!

One of the easiest ways to identify these spiders in Uganda is to look for their egg sacs. They have pointy protrusions and are frequently referred to as “fluffy” or “spiky” in appearance.


#3. African Hermit Spider

  • Nephilingis cruentata

Spiders of Uganda

Identifying Characteristics:

  • Females grow up to 25 mm (1 in). Their bodies are elongated and pointed, bright yellow near the head and dark brown near the back.
  • Males grow only up to 4 mm (0.15 in).
  • The legs of both sexes are a combination of brown, red, and black.

African Hermit Spiders get their common name from building funnel-shaped retreats on the side of their webs. They hide out in the funnels during the daytime, emerging at night to hunt.

Their asymmetrical webs are usually found on trees and bushes in tropical and subtropical climates. African Hermit Spiders live close to people and can be spotted in manufactured structures on walls and roofs. But don’t worry, this fearsome-looking spider isn’t dangerous to humans!

If you find an African Hermit Spider in Uganda, it’s most likely a female. That’s because the males are so small they’re hardly ever spotted. In fact, they have the greatest sexual dimorphism of any spider in Uganda. Females are up to 14 times bigger than males and up to 70 times heavier.


#4. Gray Wall Jumping Spider

  • Menemerus bivittatus

Types of spiders in Uganda

Identifying Characteristics:

  • This species has a flattened torso and short, thick, greyish-white hair. Tufts of dark brown hair grow close to the eyes.
  • The male has a brownish-white stripe on each side of the abdomen and a black dorsal stripe.
  • The female has a larger abdomen and is typically lighter brown. In addition, her abdomen is rimmed with broad black stripes that come together at the end.
  • Both sexes are about 9 mm (0.3 in) long, but males are usually slightly smaller.

The Gray Wall Jumping Spider is native to Uganda but has since spread throughout the world. It frequently appears on the exterior of buildings or tree trunks in gardens.

Instead of weaving a web around their prey, the Gray Wall Jumping spider stalks the prey before springing on it to attack. Their wide eyes and visual acuity allow them to easily focus on objects and distinguish between different colors. And, using their exceptional jumping ability, they can seize their prey in the blink of an eye.

Interestingly, male Gray Wall Jumping Spiders can produce sounds as part of courtship behavior. The hairs on their femurs and the teeth on the chelicerae (small claws on the front of the mouth) make clicking noises that attract females. These sounds are too low and quiet for humans to hear, but it isn’t hard to imagine the creepy noise!


#5. Adanson’s House Jumper

  • Hasarius adansoni

Identifying Characteristics:

  • Males have more colorful bodies, with black abdomen color and two white crescents on their bodies. They grow up to 6mm (0.23 in).
  • Females are dark brown and don’t have any noticeable pattern, and are about 8mm (0.31 in) long.
  • Both sexes have long legs covered with spines and hairs.

The Adanson’s House Jumper lives in warm climates all over Uganda. Its natural habitats include woodland and low vegetation, but since they are highly adaptable, they can be found in any terrestrial area.

Although they can reuse their nests, they usually build new ones each night. Their webs are relatively small, about twice the size of the spider. The Adanson’s House Jumper is quite sociable and can be seen grouped in bigger numbers.

One of the most interesting traits of this species is its ability to jump incredible distances. They hunt by leaping several centimeters onto their prey, grabbing them, and injecting venom by bite.


#6. Shorthorn Kitespider

  • Gasteracantha sanguinolenta

Also known as the Thorn spider, the Jewel spider, the Star spider, or the Kite spider.

Identifying Characteristics:

  • Females are 8-10 mm (0.31-0.39 in) long. They’re bright cream, white or yellow, red, and black. Their abdomen is usually black at the sides and white at the center, with red spots.
  • Males are several times smaller and lack bright coloring.
  • Their abdomen is sclerotized (hardened) with four sides and two back spines.

Unlike other spiders in Uganda, this species is most commonly seen during winter.

They reproduce in the spring, and the females die after producing the egg sac, leaving the young to grow and disperse on their own.

The Shorthorn Kitespider is mostly found in evergreen forests, woodlands, or shrubby gardens. They use trees to build their webs at least one meter above the ground.


#7. Bark Spiders

  • Genus Caerostris

Note: Bark Spiders are a genus of 18 species that range over the African continent.

Identifying Characteristics:

  • Females are black or brown, with long white hairs on the upper body. Some individuals are spotted with red, yellow, or orange.
  • Males have a lighter color, usually without any spots. In addition, they are considerably smaller, one-third of the length of an average female.

Bark Spiders are a genus of orb-weaving spiders in Uganda, most commonly found in tropical climates.

They get their name from their incredible effective camouflage, which helps them blend into tree bark as they climb and move throughout the forest.

The silk that Bark Spiders produce is the toughest biological material humans have ever studied, twice as strong as any other spider silk known to science. And not only do Bark Spiders have the strongest silk, but they also build the largest webs. This impressive species holds the record with a surface area of up to 2.8 square meters (30 sq ft).

Perhaps the most fascinating thing about Bark Spiders is the unique location of their webs. They construct them directly above a river or stream, so insects flying above the water are snared in its web. This genus has both brawn and brains!

  1. these all are quite small. I had expected tarantula size! a pleasant surprise. I probably will never be able to visit even though the country is beautiful, but having no large spiders is a big plus!
