Crocidolomia pavonana is a moth of the family Crambidae.Its caterpillar is a crop pest and is known as the croci or the cabbage cluster caterpillar.This moth is found in Africa and Asia, its range extending from South Africa through India to the Pacific Ocean, including Australia.
Clusters amplify the signal of aposematic coloration, and individuals may participate in group regurgitation or displays. Pine processionary (Thaumetopoea pityocampa) caterpillars often link into a long train to move through trees and over the ground. The head of the lead caterpillar is visible, but the other heads can appear hidden. [22]
The chemical recruitment trail of the eastern tent caterpillar is remarkably similar to the pheromone trails that are used by ants and termites to alert nest mates to the discovery of food. Leaves consist largely of nondigestible components, and it has been estimated that tent caterpillars void as frass (fecal pellets) nearly half of the energy ...

Nudaurelia cytherea, also called the pine tree emperor moth or Christmas caterpillar due to its festive colouration, is a southern African member of the family Saturniidae. The family has large edible caterpillars which are an important source of protein for the Bantu peoples of southern Africa.
Archips cerasivoranus feeding on the leaves of choke cherry, Prunus virginiana. Social caterpillars grouped on a tree on the banks of the Napo River, Tena, Ecuador. The collective behaviors of social caterpillars falls into five general categories: collective and cooperative foraging, group defense against predators and parasitoids, shelter building, thermoregulation and substrate silking to ...
Species that parasitize microlepidopterans, for instance, have longer ovipositors, presumably to reach the caterpillar through layers of plant tissue. Some wasps also have long ovipositors to bypass caterpillar defense mechanisms such as spines or hairs, or to reach deeply-burrowed Coleoptera larvae in tree trunks.
The larvae hatch and are active in the spring. These insects are called fall cankerworms because the females emerge from the soil in November, mate and lay their eggs in clusters on hardwood trees. [2] There are some natural enemies of this species. Many birds eat the caterpillars. The ground beetle, Calosoma frigidum also feeds on the ...
