Misumena vatia feed on common insects, often consuming prey much larger than themselves. They use venom to immobilize their prey, though they are harmless to humans. They face threats due to parasites and larger insects. For Misumena vatia, survival depends on the choice of hunting site. The spiders closely monitor multiple sites to see if ...
Some species sit on or beside flowers or fruit, where they grab visiting insects. Individuals of some species, such as Misumena vatia and Thomisus spectabilis, are able to change color over a period of some days, to match the flower on which they are sitting. Some species frequent promising positions among leaves or bark, where they await prey ...
The tribe Misumenini belongs to the crab spider family, Thomisidae. As circumscribed by Lehtinen, typical members of the tribe Misumenini have a greenish body and legs (in fresh specimens), and a relatively uncomplicated colour pattern.
Misumena vatia, the goldenrod crab spider, is a North American species commonly seen hunting in goldenrod (Solidago) sprays in autumn. It can change its color between white and yellow to match the flower it is sitting on.
The ability of Thomisus spectabilis to change color is shared by Misumena, Diaea, and Runcinia spiders which are also members of the Thomisidae family and have high genetic relatedness with the Australian Crab spider. Misumena vatia is a close relative of T. spectabilis but instead has a holarctic distribution.
Thomisus Onustus in Behbahan, Iran. The distribution of Thomisus species is almost worldwide, with the notable exception of most of South America. [5] Although Thomisus species can be found almost anywhere on earth, most species occur in the tropics and the warmer regions of the Old World, with fewer species in the region from New Guinea to Australia and the New World.
The female Misumenoides formosipes, while similar to Misumena vatia, is not as large, and can be distinguished by the inverted 'V' marking on its back (with the point of the V closer to the cephalothorax) and the 'mask' over its eyes.
It is a species of the 'flower spiders', so-called because they generally hunt in similarly coloured flowers for visitors such as bees and flies, and is a much smaller nearctic relative of the better-known Goldenrod Spider (Misumena vatia).
