What do the larvae of a firefly look like

If you look closely at the larvae of a firefly, you will find that on the ventral surface of the end of the firefly's abdomen, there are some special structures of yellowish white, which is its luminous device.

There are more than 15,000 light-emitting cells inside, which mainly contain two luminescent substances: luciferin and luciferase. In addition, there is also a high-energy compound called adenosine phosphate that is present in the body of fireflies.

Luciferin and luciferase can produce a certain amount of sparkle under the action of adenosine phosphate. For the fireflies themselves, the main role of these luminescent chemicals is for courtship.

When night falls, you can see the flash of fireflies, which indicates the arrival of the firefly mating season. Male fireflies generally take off from the ground and emit a strong flash of light to attract the opposite sex, while female fireflies sting on the ground and also emit flashes of light as a response signal. When the signals from both parties are "communicated", the courtship is successful and the mating begins.

In addition, the flash of fireflies has a warning effect and can defend against predators.

Yes, the larvae of fireflies.

It's firefly larvae.

The shape is as follows:Firefly. Their bodies are long and flattened, with walls and elytra.

Supple. The dorsal plate of the anterior thorax is flat, often covering the head. The head is narrow. The eyes are semicircular and spherical, and the eyes of males are often larger than those of females. The abdomen is 7 and 8 segments, with a luminous apparatus under the end, which can glow yellowish-green. Fireflies are amazing and beautiful insects.

Introduction:

Fireflies feed on pests such as snails and snails that are harmful to crops in paddy fields, snails like to eat some tender vegetable shoots, while fireflies like to eat snails. Fireflies are one of the indicators of environmental quality, and the place where they live must have fresh air and pure water. So in this way, fireflies belong to beneficial insects. One.

The physical characteristics of fireflies are as follows:1. The body length of the firefly is about centimeters, the body shape is flat and slender, the head is small, the body wall and elytra are soft, and the head is covered by a large anterior chest cover.

2. The antennae of the male insect are long, with 11 segments, and are flattened or serrate.

3. The abdomen can see 6 7 segments of the web, and there is a luminous device at the end, which can fluoresce.

4. Most males have wings.

Habits of fireflies:Fireflies are divided into two categories, terrestrial and aquatic, according to their living environment, with the former accounting for the majority. Terrestrial firefly larvae mostly inhabit places with high shading, lush herbaceous vegetation and high relative humidity, and each insect state of aquatic fireflies has different ecological habitats. The pupal stage is spent next to the water.

Adults are divided into males and females on plants in open water and near the water, and their eggs are laid on the shore.

Depending on the species, the adults of fireflies have different time of day, day and night, and nocturnal types appear from 6 p.m. to 3 a.m. and 4 a.m. Generally speaking, most species start their activities after sunset, and most of them stop at 8 p.m. or 9 p.m. Firefly larvae appear at night for about the same time as adults, but they can be active all night.

1. The appearance of fireflies: the insects of this family are small to medium-shaped, long and flat, and the body walls and elytra are soft. The head is small, and the dorsal plate of the anterior thorax is well developed, covering the head.

The eyes are semicircular and spherical, and the eyes of males are often larger than those of females. In front of the forehead, there is a pair of antennae between the two eyes, the antennae are close to the left and right, 11 segments, serrate, and the male is ctenodont or fan-shaped. The palate is curved and has grooves throughout.

Males — have elytra that cover the abdomen and hindwings. Females are often wingless, but both females and males of the genus Yellow Firefly have wings. The surface of the elytra is densely covered with fine short hairs, and the elytra are folded at the base broad.

The basal ganglia of the forefoot is conical with subbasal ganglia; The basal ganglia of the midfoot are cylindrical, and the two basal ganglia are close to each other; The basal segment of the hindfoot is transversely broad. The foot is elongated, without special enlargement, and the tarsal nodes are 5 segments. Abdomen 7 8 segments, the first segment has a luminous device, can glow yellow-green light.

The larvae are brown, long and flattened, with thin anterior and posterior ends, distinct body segments, and well-developed heads and feet. There is a luminaire on the 8th segment of the abdomen.

2. Characteristics of fireflies: Fireflies are carnivorous organisms, and the larval stage mainly eats snails, snails and shellfish; Fireflies have a larval period of up to a year until they grow wings and become adults. Fireflies in the adult stage are busy mating and laying eggs, and can only survive for about a week.

During this time, they stop hunting, just drink some dew or collect some nectar until they starve to death.

The body of the <> firefly larvae is long and flattened, and the head is a pair of retractable antennae, two monocular and other appendages, the most obvious of which is a large dark brown needle-like jaw.

The thorax has three segments, nine abdominal segments, and six slender feet, the noisy eighth abdominal segment has two luminous devices, and the ninth abdominal segment has a sucker-like tail foot that can be used to attach to objects. ** The upper ones are the larvae of fireflies.

The larvae of fireflies are meat-eating, and the larvae of terrestrial fireflies mostly eat some smaller snails; Most of the aquatic firefly larvae of cattle eat snails in the water, and sometimes they also eat small fish and tadpoles.

As shown in the picture above.
