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

The whitebanded crab spider is a little spider that sits very still on flowers. It has a thin white line across its face, below its eyes. The female can slowly change colour between white and yellow to match the flower she is sitting on.

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

Fun facts

1

It does not build a web. Instead it uses flowers as a hiding place and waits for its food to land.

2

It is called a crab spider because its body and strong front legs look a bit like a crab.

3

Changing from white to yellow takes the female more than three days, and changing back takes even longer.

4

The male is tiny next to the female. He finds her by following the smell of the flowers.

5

The mother lays up to 180 eggs in a silk bag and guards it for the rest of her life.
