You have 20/20 vision if you can spot the caterpillar in under 5 seconds

ONLY people with 20/20 vision can spot the caterpillar in an optical illusion.

Although the caterpillar is cleverly camouflaged on the twig, the challenge is only made more difficult with a time limit of five seconds.

A photo of branches to the unsuspecting eye looks to be just that, a photo of some tree branches.

Take a closer look, however, and you may be able to spot the caterpillar curled up on the right-most branch, blending right in.

Many animals can alter their appearance to protect themselves against predators, with fragile caterpillars being no exception.

Various species, such as the common baron, maple spanworm, and pepper moth larvae are true masters of camouflage.

The caterpillar in the photo is a maple spanworm, part of the Geometridae family which includes “inchworms,” caterpillars that look like they “inch” along when they walk.

Geometridae caterpillars move by bringing their rear legs up behind their front legs and then straighten out for the next step.

While maple spanworms are a common presence among trees, they easily fly under the radar thanks to their powerful camouflaging ability.

When a maple spanworm senses that someone or something is nearby, it exercises precautions on the chance that it may be a predator.

The spanworm grabs hold of the branch or tree it’s on with its legs and holds its body out straight.

In this position, the spanworm looks exactly like the stick it’s sitting on.

If you succeed in finding the caterpillar, give yourself a pat on the back because it means you have sharp vision.

If you made it this far, congratulations! If you weren’t able to find the caterpillar, there are plenty more optical illusions to try.

See if you can find all four women hiding in this optical illusion.
