Larva — Lepidoptera

What is an opportunist?

An "opportunist" is a population (fungi, bacteria, insects…) that takes advantage of a favourable environment to settle in, multiply and feed on it. It often develops when the natural defences of the affected organism are weakened — for genetic reasons or linked to context (water stress, deficiencies, nutritional imbalances, overcrowding…). This is typically the case in monocultures, where a single host plant, uniform and present in large numbers, offers ideal ground for it to spread.

Identification key : Leaf-eating caterpillar (Larva) Looper caterpillar (geometrids and allies) (Larva) Leaf-mining caterpillar (Larva) Boring caterpillar (fruits, stems, cobs, tubers, wood) (Larva) Hairy caterpillar (processionary and allies) (Larva)

Scientific name : Lepidoptera

Other names : moth larvae, cutworms

Caterpillars are the larvae of butterflies and moths (order Lepidoptera); adults lay eggs on plants and the hatching caterpillars feed for several weeks before turning into a pupa. Depending on the species, they chew leaves leaving holes or only the veins, cut seedlings off at ground level (cutworms), bore into stems and fruit, or spin silk nests. They attack cabbages, tomato, maize, lettuce, beans, grapevine, fruit trees and ornamentals, and their droppings and chewed leaves often reveal their presence.

Crops affected : Apple tree, Bean, Broccoli, Cabbage, Cauliflower, Corn, Cotton, Lettuce, Nursery roses and shrubs, Peach tree, Potato, Soybean, Tempranillo, Tomato
