wanderer

The term "wanderer" can refer to the larva of the harvester butterfly (Feniseca tarquinius), which is known for its predatory habits, feeding on aphids. This larva is also described as squat and hairy.1

In a broader sense, a larva is an immature stage in the life cycle of many animals, occurring after birth or hatching and before reaching the adult form. Larvae are structurally different from adults and are adapted to different environments. They often serve as a food-gathering stage, with a well-developed digestive system, and can also aid in the dispersal of the species.2

For insects like moths and butterflies (order Lepidoptera), the larva is commonly called a caterpillar. Caterpillars are primarily plant-eaters and are relatively simple and primitive compared to the adult form. They possess features important for classification and have a head with simple eyes, jaws for consuming plant material, and a spinneret for extruding silk. They also have thoracic legs and abdominal prolegs equipped with hooks for gripping surfaces. Many caterpillars produce silk for grip, protection, and forming cocoons for pupation.34
