eruciform larva

In zoology, an eruciform larva is a type of insect larva that resembles a caterpillar. These larvae typically have soft, cylindrical bodies with distinct heads and short thoracic legs. While most commonly associated with butterflies and moths (Lepidoptera), caterpillar-like larvae also appear in other insect groups, such as scorpionflies (Mecoptera) and sawflies (Hymenoptera).12

Caterpillars, the most well-known eruciform larvae, are characterized by their voracious appetites and are known for consuming large amounts of plant matter. They possess three pairs of true legs on their thorax and several pairs of prolegs on their abdomen. Their heads have small eyes and strong jaws. Caterpillars employ various defense mechanisms, including camouflage, the release of foul-smelling chemicals, and the sequestration of toxins from their food.3
