Goldenrod crab spider

Misumena vatia

''Misumena vatia'' is a species of crab spider with holarctic distribution. In North America, where it is the largest and best-known flower spider, it is called the goldenrod crab spider or flower spider, because it is commonly found hunting in goldenrod sprays in the autumn. Young males in the early summer may be quite small and easily overlooked, but females can grow up to 10 mm ; males reach 5 mm at most.
