Goldenrod crab spider

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

The goldenrod crab spider sits on flowers and waits for visitors. It is white or yellow, and it can slowly change colour to match its flower. Like a crab, it can walk sideways, and it holds its long front legs open, ready to grab.

Fun fact: spiders are not insects. Insects have six legs, spiders have eight. Everyone calls them bugs anyway!
Lives in
Europe and North America, on flowers in meadows and gardens
Length
0.5 to 1 cm (0.2 to 0.39 in)

What does it eat?
It catches insects that come to the flower, like flies and bees, and often grabs prey much bigger than itself.

The female is about twice as long as the male, which is at most 5 millimetres long.

4

Females leave a silk safety line behind them, and males follow it to find them.

5

On a yellow goldenrod flower it is so well hidden that even people searching for it can hardly see it.
