Anoplius depressipes
Anoplius depressipes is a spider wasp in the family Pompilidae, notable for its specialized hunting of fishing spiders in the genus Dolomedes. The species exhibits remarkable aquatic adaptations, including the ability to walk on water and dive underwater for several minutes to capture prey that attempts to escape beneath the surface. This wasp represents a striking example of predator-prey coevolution with semi-aquatic spiders.
