Why jumping spiders mimic wasps

In nature's game of survival, appearances can deceive

Earth.com highlighted a study by biologists at the University of Cincinnati that found spiders that look like wasps can fool not only other spiders but also artificial intelligence.

Scientists for years have been struck by how some male jumping spiders resemble wasps when they raise their abdomen's during their courtship rituals. Australian researchers who discovered one new species named it after the Latin name for wasp.

Biologists in UC's College of Arts and Sciences discovered that the ruse tricks even artificial intelligence that could not always correctly identify the jumping spiders among images of wasps, flies and praying mantises.

Mimicry is a common strategy in nature. But why would a spider want to mimic a wasp, which hunts and feeds on spiders?

UC Associate Professor Nathan Morehouse, a study co-author, said the male spiders might use the ruse to capture the attention of females. And once they have their potential mate's attention, they can make introductions through their elaborate courtship rituals.

The study was published in the journal Behavioral Ecology.
