What kinds of spiders can you find in Rwanda?

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 Rwanda. 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.

ONLY common SPIDER in Rwanda!

#1. 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 Rwanda, 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!
