Citrus swallowtail
The citrus swallowtail is a big butterfly with black and yellow wings and little red and blue eye spots. It lives all over Africa south of the Sahara desert. Its caterpillars love the leaves of lemon and orange trees.

How fast is it?
Fun facts
A young caterpillar is black, yellow and white, so it looks just like a bird dropping. Birds do not want to eat that.
An older caterpillar turns green. When a bird comes close, it pushes out a forked orange horn that gives off a strong smell.
Because of that orange horn, the caterpillars are sometimes called orange dogs.
The female lays her eggs one by one on citrus leaves, and they hatch after about six days.
There can be about three families of these butterflies in one year.
