Butterfly Tasting Series – Larval Growth Process

author:Brother Protector

Everyone can see the beauty of butterflies, so do you know how butterflies grow? Let me give you a detailed introduction.

The life history of butterflies and moths is complex and consists of four stages: egg, larvae (caterpillars), pupae, and adults. The larvae during the egg stage develop in a protective shell. The larval stage is the main feeding phase, and the larvae must molt several times in order to grow. During the pupal stage, parts of the body disintegrate and transform into mature butterflies or moths. We call this life history complete perversion.

Butterfly Tasting Series – Larval Growth Process

Larval growth process

It can be seen in the picture that the egg darkens the color of the egg before the larvae are about to hatch, and the small larvae can be seen wriggling inside. First bite through a round "cap" (A) on the tough egg shell, and then creep the body out of the shell (B and C), which is one of the most vulnerable stages. The larvae emerge (D) and often gnaw at its empty egg shell (E) as a survival nutrient until it can climb onto the fodder plant.

The process of larval pupation

The larvae take citrus butterflies as an example, where the larvae select appropriate shoots and spit out silk pads to stick to its tail (F). Then, another ring or "band" is spit out, which goes around the middle of the body so that it connects with the plant branches to support itself (G) The epidermis of the larvae splits along the back and pupae begin to appear (H). Through a series of peristalsis, the larvae's old skin is forced to withdraw towards the tail. The old skin falls off, and there is a series of hooks on the tail, hooked into the human support silk pad, at which point the pupae is formed.

The process by which the pupae grow into a butterfly (moth).

The color of the butterfly is hazy and visible before the pupae are about to feathering (J). The pupae shell breaks and the butterfly begins to break out (K). When completely free (L), the butterfly excretes a fluid called pupal stool from the end of the abdomen, which is waste that accumulates during pupal phase. After the butterfly has feathered, after a short rest, it quietly hangs down its wrinkled wings and presses blood into the wing veins to spread the wings (M). The wings must spread quickly before they harden, or they will be permanently deformed.

Friends, look at things not only by beautiful appearance, but also by understanding its growth process, and now we know the difficult process of butterflies breaking out of their cocoons.
