Are Butterflies Insects? Analyzing the Insect Characteristics of Butterflies from Their Morphological Features

Butterflies are also known as brush-footed butterflies, Hu die, Fu die er, die, and so on. They are generally brightly colored, with many stripes on their bodies and rich colors, and various markings on their wings and bodies. There are about 14,000 species worldwide, most of which are distributed in the Americas, especially in the Amazon River basin, where the greatest variety is found. There are 1,200 species in China. Let us take a look below at whether butterflies are insects!

Are butterflies insects?

Butterflies are insects. Butterflies are the general term for animals in the phylum Arthropoda, class Insecta, order Lepidoptera, suborder Rhopalocera. They are classified under Lepidoptera, and tens of thousands of species worldwide are placed in this group. Since the Cretaceous period, they evolved along with flowering plants that served as food and pollinated them. They are the last group of organisms in insect evolution. The main difference from moths is that butterflies have a pair of club-shaped or hammer-shaped antennae on the head, while the antennae of moths vary in shape.

What do butterflies eat?

1. Larvae: The feeding targets of butterfly larvae differ according to species. Most larvae feed on leaves. Some species, such as the pollen butterfly and the orange-banded orangetip, feed on flower buds. There are also some species that bore into and feed on tender pods or young fruits. For example, the pea blue bores into and feeds on tender pea pods, and the gardenia blue bores into and feeds on young gardenia fruits. In addition, among the Lycaenidae, a small number of species have carnivorous larvae. For example, the coffee scale blue feeds on coffee scales, and the bamboo aphid blue feeds exclusively on bamboo aphids. Such carnivorous species are rare among butterflies and are beneficial insects.

2. Adults: Most butterflies feed on nectar. As for butterflies that feed on nectar, they do not only take nectar; they also like to feed on the nectar of certain specific plants. For example, the blue swallowtail especially likes to feed on the nectar of plants in the Liliaceae family, the cabbage white especially likes to feed on the nectar of plants in the Brassicaceae family, and the fritillary especially likes to feed on the nectar of plants in the Asteraceae family, and so on. Some butterflies that do not feed on nectar include the bamboo-eyed butterfly, which feeds on fig sap, and the pale purple fritillary, which feeds on the sour sap of diseased oak and poplar trees. Some butterflies also feed on the flesh of grapes, and butterflies are commonly seen feeding in grape fields.

The growth process of butterflies

1. Eggs: Butterfly eggs are generally round or oval, with a waxy shell on the surface to prevent water evaporation, and a small pore at one end that serves as the passage for sperm to enter. The size of butterfly eggs varies greatly among different species. Butterflies generally lay their eggs on the leaf surfaces of plants that the larvae like to eat, preparing food for the larvae.

2. Larvae: After the larvae hatch, their main activity is eating. They need to consume large amounts of plant leaves. Larvae come in various shapes, mostly fleshy worms, with a few being hairy caterpillars. Butterflies mainly harm agriculture during the larval stage. As the larvae grow, they generally undergo several molts.

3. Pupae: After the larvae mature, they become pupae. The larvae usually attach themselves in hidden places on the underside of plant leaves, fixing themselves with a few threads, and then directly pupate, without a cocoon.

4. Adults: After the pupa matures, the butterfly breaks out of the pupal shell, but it needs a certain amount of time for its wings to dry and harden. At this time, the butterfly cannot avoid natural enemies, and this is a dangerous period. After the wings spread out, the butterfly can fly. The forewings and hindwings of butterflies do not flap in sync, so butterflies wobble greatly when flying, with graceful postures. The so-called “dancing gracefully” comes from the flight of butterflies. Generally, after adult butterflies mate and lay eggs, they die before winter arrives, but some species migrate south to spend the winter.
