White crab spider

Eats: Other bugs and small animalsSpidersGardens and meadows8 legsNot an insect, but a bug cousin

The white crab spider is a small white or yellow spider that sits very still inside flowers. Its strong front legs stick out to the sides like a crab's claws. Across its face it has a white band with tiny black eyes that looks like a little mask.

Fun fact: spiders are not insects. Insects have six legs, spiders have eight. Everyone calls them bugs anyway!

What does it eat?

Fun facts

1

It can change its colour from yellow to white to match the flower it is hiding in.

2

It does not spin a web. It waits in a flower and grabs bees and butterflies with its front legs.

3

Its body shines in ultraviolet light, a colour that bees can see and we cannot. This makes bees fly right up to its flower.

4

With its legs spread out it is about 3 centimetres across.

5

The mother lays 200 to 370 cream coloured eggs inside a folded leaf.
