pilosicoli

Pilosicoli, also known as hairy caterpillars, are a group of caterpillars that have a distinctive feature of having long, fine hairs covering their bodies. These hairs, known as setae, are often used for sensory purposes, helping the caterpillars detect changes in their environment. The setae can also serve as a defense mechanism, making the caterpillar less palatable to predators. Pilosicoli are found in various families of moths and butterflies, and their presence is often an indicator of the presence of their adult counterparts.

The term "pilosicoli" is derived from the Latin words "pilosus," meaning hairy, and "coleus," meaning a caterpillar. The group is taxonomically diverse, with representatives found in different orders and families of insects. Some well-known examples of pilosicoli include the larvae of the cabbage white butterfly (Pieris brassicae) and the larvae of the silkworm (Bombyx mori).

Pilosicoli play a crucial role in the ecosystem as they serve as a food source for various predators, including birds, reptiles, and amphibians. They also contribute to the nutrient cycle by decomposing plant material. Despite their ecological importance, pilosicoli are often overlooked in insect studies due to their small size and the fact that they are often found in hidden or protected environments.
