What is the name of the butterfly larva?

The larvae of butterflies are called caterpillars, and their activities and habitat habits come out when the sun shines obliquely in the morning and evening.

The feeding objects of larvae are different according to different insect species, and most larvae like to eat leaves; Some species, such as pink butterfly, orange-spotted pink butterfly and other flower buds; There are also some species that feed on young pods or young fruits, such as the pod gray butterfly that feeds on young pods and the gardenia gray butterfly that feeds on young gardenia fruits.

Larvae that feed on plant leaves, such as the first instar, often eat mesophyll on the back of leaves and leave the upper epidermis to form transparent spots similar to glass windows. Later, larvae feed on leaves, or nibble inward from the edge of leaves; As the bug grows up, it eats more and more. When the insect population density on a plant is high, the whole plant will be eaten up.

Extended data:

A butterfly's life will go through four stages: egg, larva, pupa and adult.

1. Egg: Butterfly eggs are generally round or oval, with a waxy shell on the surface to prevent water evaporation, and a fine hole at one end, which is the passage for sperm to enter.

2. Larvae: After larvae hatch, they mainly eat food and eat a lot of plant leaves. Larvae have various shapes, most of them are carnivores, and a few are caterpillars. Butterflies mainly harm agriculture in the larval stage. As the larva grows, it usually goes through several molts.

3. Pupa: The larva will become a pupa when it matures. Generally, larvae are fixed in a hidden place on the back of plant leaves with a few iron wires, and then pupate directly without cocoon formation.

4. Adult: After the pupa matures, the shell breaks out from the pupa, but it takes some time for the wings to dry and harden. At this time, butterflies can't avoid natural enemies, which is a dangerous period. Butterflies can fly when their wings are spread.
