do wasps have good eyesight

The work was supported by a grant from the National Science Foundation (IOS-1146139). Like all insects, they have compound or faceted eyes, each a cluster of thousands of small, telescope-like omatidia with an outer lens that focuses light onto sensory cells inside the eye.

Snakes have infamously poor eyesight, which is why they resort to sticking out their tongues all the time to get a sense of their surroundings.

There are plenty of animals that have an incredible sense of sight and use it for their survival. Tibbetts, associate professor of ecology and evolutionary biology, and Sheehan discovered three years ago that some paper wasps learn and recognize the colorful facial patterns of other wasps in the colony, just as humans recognize others’ faces. You might have trouble seeing some colors. The paper wasps with variable facial patterns are mostly species in which several queens sometimes cooperate to establish a colony, which would make the ability to discriminate among individuals important, he said.

Indeed, wasps do sting, and wasp stings hurt. But most wasps are actually solitary, non-stinging varieties. '”, For some paper wasps, Sheehan said, “We found convincing evidence that the wasps evolved better vision for the purpose of telling one another apart. “The Big Bad Wolf had it right,” said lead author Michael Sheehan, a UC Berkeley postdoctoral fellow.
