Praying Mantises Are More Badass Than We Realized. Praying mantises are among the most frightening insects on the planet, equipped with powerful front legs which they use to snatch unwary insects, spiders, and even the odd amphibian or reptile. But as new research reveals, praying mantises are also proficient at capturing birds—which they do more often than we thought. New research published in The Wilson Journal of Ornithology shows that small birds often fall victim to praying mantises, and that this behavior exists among many different mantis species around the world. Most cases of this insect- on- bird violence were documented in North America, where small birds—particularly hummingbirds—are snatched by the predatory insects when visiting feeders or house gardens.
