Goldenrod crab spider
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 facts
Changing from white to yellow is slow. It can take up to 25 days.
Sometimes, if it eats a brightly coloured insect, the spider itself takes on that colour.
The female is about twice as long as the male, which is at most 5 millimetres long.
Females leave a silk safety line behind them, and males follow it to find them.
On a yellow goldenrod flower it is so well hidden that even people searching for it can hardly see it.
