Brazilian Wanderer Spider Wasp
A large metallic blue-black spider wasp with bright orange wings that hunts tarantulas as food for its larvae. The female paralyzes a tarantula with her sting, then drags it to a burrow where a single egg is laid on the spider. The larva consumes the still-living spider from the inside.
Did You Know?
Its sting is rated among the most painful of all insect stings, scoring a 4 out of 4 on the Schmidt Pain Index.
Queenless Ponerine Ant
A large black ponerine ant found across South and Southeast Asia that lacks a morphological queen caste. Instead, a single mated worker called a gamergate monopolizes reproduction.
Did You Know?
The gamergate maintains her dominance by mutilating the gemmae of newly emerged workers, preventing them from mating.
