If you don't immediately see both katydids in this photo, don't feel bad. Their leaflike bodies also help them evade countless birds, frogs, snakes and other predators around the world.
Katydids are typically not seen but heard, rubbing their wings together to make the namesake "katy-did" sound. Unlike their cricket relatives, however, katydids produce egalitarian music, with both males and females chiming in. Some prey on smaller insects, but their favorite food — foliage — is obvious from their appearance. And much like caterpillars, katydids' love of leaves often puts them at odds with farmers and gardeners, just one more group of predators who struggle to see through their camouflage.
