Pisaura mirabilis

Description:

In a Columbine leaf, the female spider protects her cocoon. She is light brown, about 3, 5 cm long with legs, cocoon has a diameter about 2 cm Males of this species offer food gifts to potential female mates. Some Pisaura mirabilis have also been observed to feign death, remaining still while holding the food gift in their mouths. When the female approaches and tries to take the food away, the male springs back to life and attempts to mate. The strategy of playing dead more than doubles a male's odds of successfully achieving copulation, from 40% to 89%.This is an example of a behavior originally evolved to ward off predators being adapted to a new purpose.

Habitat:

garden

Notes:

I let her in peace, in the leaf, didn´t damage her web.
