Amyciaea is a genus of ant mimicking crab spiders that was first described by Eugène Louis Simon in 1885. They mimic weaver ants, their preferred prey. Wikipedia
Spotted at Dover – March 2021
More than 300 species of spiders are known to mimic the outward appearance of ants, a phenomenon called myrmecomorphy.
The spiders also behave like ants by waving their front pair of legs near their heads like antennae, and adopting an erratic zig-zag pattern of movement that is more like ants than spiders.
Aggressive crab spiders typically jump on a lone unsuspecting ant and bite it. Then, in order to avoid encounters with other ants, the spider and its victim fall away on a safety line made of the spider’s silk while the venom takes effect. Others, like the ant-mimicking ground spider, use the body of their dead prey as a shield, holding it up between themselves and any other challenging ants. This tricks attacking ants into believing that the spider is just another ant, carrying a dead nest-mate away from their nest. Spiders disguise themselves as ants to hide and hunt their prey
