A fossilized ant-mimicking spider reveals the evolutionary tactics spiders use to avoid predators, emphasizing the adaptive benefits of mimicry in the spider kingdom.
The age of the resin in this case, however, could not be determined, said Poinar, an international expert in using plant and animal life forms preserved in amber to learn about the biology and ecology of the distant past. To get around those anatomical differences, Poinar said, spiders typically position their two front legs in a way that approximates the look of antennae. But number of legs and absence/presence of antennae are not the only characteristics differentiating an ant’s appearance from a spider’s.
Most of the copycat spiders belong to a few families of hunting spiders, including Salticidae or jumping spiders. The specimen in the Colombian copal appears to be a jumping spider.
