In the animal world. Spider crusader

On the back has spots in the form of a cross.

 It serves to scare away animals. He launches his digestive juices into the victim's body, then drinks the resulting liquid.

 Between the branches arranges a network of hunters, and from the leaves makes himself a refuge. The poison is toxic to invertebrates and vertebrates.

 After mating, the male dies, and the female weaves a cocoon for eggs from the web. 

Eggs are laid in the fall.
