Common bark spider

Caerostris sexcuspidata
Eats: Other bugs and small animalsSpidersForests and woods8 legsNot an insect, but a bug cousin

The common bark spider is a master of hiding. Its brown, bumpy body looks just like a piece of tree bark. By day it sits very still on a branch, and at night it builds a big round web between trees.

Fun fact: spiders are not insects. Insects have six legs, spiders have eight. Everyone calls them bugs anyway!
Lives in
Africa from Cameroon and Ethiopia to South Africa, and Madagascar, in trees and orchards
Top speed
about 1.2 km/h (0.75 mph)
On foot, estimate
