Many caterpillars display feeding behaviors which allow the caterpillar to remain hidden from potential predators. Many feed in protected environments, such as enclosed inside silk galleries, rolled leaves or by [[leaf miner|mining]] between the leaf surfaces.

Some caterpillars, like early instars of the [[tomato hornworm]] and [[tobacco hornworm]], have long "whip-like" organs attached to the ends of their body. The caterpillar wiggles these organs to frighten away flies and predatory wasps.<ref>{{Cite book|last = Darby|first = Gene|title = What is a Butterfly|publisher = Benefic Press|location = Chicago|year = 1958|page = 13}}</ref> Some caterpillars can evade predators by using a silk line and dropping off from branches when disturbed. Many species thrash about violently when disturbed to scare away potential predators. One species (''[[Amorpha juglandis]]'') even makes high pitched whistles that can scare away birds.<ref>{{Cite journal | last1 = Bura | first1 = V. L. | last2 = Rohwer | first2 = V.
