Larva in apple fruit. Once the caterpillar has located a fruit to feed on, it starts penetrating the epidermis of the fruit. As the caterpillar makes way into the fruit, scraps of the skin, pulp, and frass build up near the entrance of the hole. These pieces are glued together by silk threads released from the caterpillar to create a cap.
The digestive physiology of tent caterpillars is tuned to young leaves, and their need to complete their larval development before the leaves of the host trees become too aged for them to eat compels them to feed several times each day. At the onset of a bout of foraging, caterpillars leave the tent en masse, moving to distant feeding sites.
Caterpillars have been called "eating machines", and eat leaves voraciously. Most species shed their skin four or five times as their bodies grow, and they eventually enter a pupal stage before becoming adults. [23] Caterpillars grow very quickly; for instance, a tobacco hornworm will

Acleris semipurpurana is found in the eastern United States and adjoining portions of southeastern Canada.It has been found in US states ranging from New York, Massachusetts, Connecticut and Pennsylvania in the northeast to Minnesota and Texas in the west, as well as the Canadian province of Ontario.
On an early Sunday morning, "a tiny and very hungry caterpillar" hatches from his egg and immediately begins searching for food.For the following five days, the caterpillar eats through an increasing quantity of fruit: one apple on Monday, two pears on Tuesday, three plums on Wednesday, four strawberries on Thursday, and five oranges on Friday.
Forest tent caterpillars massing on a tree trunk. Eating times are variable. Foraging trips can occur at any time and are very coordinated: either the entire colony forages or no one does. A small proportion of starved individuals is enough to reach agreement and start group movement. [10]
The oak processionary (OPM) (Thaumetopoea processionea) is a moth whose caterpillars can be found in oak forests, where they feed on oak leaves, causing significant damage. They travel in nose-to-tail processions (hence their name), often arrow-headed, with a leader followed by rows of several caterpillars abreast. [ 1 ]
Choreutis pariana, the apple-and-thorn skeletonizer or apple leaf skeletonizer, is a moth of the family Choreutidae. The species was first described by the Swedish entomologist Carl Alexander Clerck in 1759.
