What do bloodworms look like, and what kind of bugs are red bugs

The bloodworm is 2 30 mm long, divided into three parts: head, thorax and abdomen, segmented, each body segment is similar in thickness, and there is no difference in the appearance of the thoracic and abdominal segments, only when the adult pupa, the abdominal segment is widened. The body color is yellow, green or brown, and some are red, so it is called "blood red worm", which can be used as bait.

Adults are similar to common mosquitoes, the main difference is that the wings have no scales, the feet are also larger, and the forefeet are generally stretched forward when they are at rest, and they keep shaking, hence the name mosquito.

The antennae are densely covered with fine hairs, like feathers; Another difference is that its mouth (mouthparts) have degenerated and are no longer capable of smoking.

Keratinized head, 2 pairs of eyespots, 1 pair of antennae, mouthparts (upper lip, lower lip, inner lip, large jaw, small jaw, tongue). The thoracic segment is segmented, and there is a pair of anterior protopeds on the ventral surface of the first thoracic segment. There are 9 segments in the abdomen, and the last segment has 1 pair of posterior protopodes.

Daphnia, commonly known as bloodworms, belong to the phylum Arthropods, Crustacea, and Gill Foot subclasses. Commonly known as fish insects. Here it is important to note the difference from the larvae of the midge, commonly known as bloodworms.

Daphnia is small, about 2 mm long, light flesh red, and lives in fresh water. The body is divided into a head and a trunk, with dorsal armor, and the trunk has 5 pairs of trunk limbs (thoracic limbs), which are motor and respiratory organs.

<> "Also known as water earthworms, they mostly live on the banks of river basins or in the sludge at the bottom of the river, dense with the sludge surface, one end is fixed in the sludge, one end stretches out the sludge to shake in the water, and when it encounters alarm, it immediately retracts into the sludge.

It's a bloodworm. Red worms are small, about 100 mm long, but their populations are more productive. The difference between the two is that the former has tail gills.

The nematode prefers to live in the mud in the mud of the micro-muddy water rich in organic matter, and usually lurks 10 cm 25 cm below the mud surface, and penetrates deep into the mud at low temperatures. Red nematodes prefer darkness and photophobia, cannot be exposed to sunlight, and feed on soil to absorb organic humus, bacteria, algae.

1: Red worms are produced by midges. In late spring and early autumn, during the peak breeding period of midges, adults are collected during the day and boxes are collected at night.

It is best to keep them in a large container that comes into contact with the air, as red insects will float to the surface and their movements will be similar to breathing, so if there are too many of them, they may lose their position and die.

2: The red nematode appeared in the water, the main reason is: the secondary water supply tank was poorly managed, not cleaned in time, and was hatched and developed by the earthworm eggs deposited in the pool; The high temperatures in spring and summer are suitable for the reproduction of nematodes.

Red nematodes live in abundance in the ducts of the lower ditch. At night, they gather together along the walls of the pool and the pipes that climb into the user's water outlet.

Daphnia, commonly known as bloodworms, is a small crustacean that belongs to the phylum Arthropods, Crustacea, and Clamocera. Called fish insects. Daphnia is small, about 2 mm long, light flesh red, and lives in fresh water.

The body is small, oval, flattened on the left and right sides, and only 1 to 3 mm long. The body has 2 shell lobes and ridges at the dorsal junction. Spikes that extend and grow at the back end.

The head sticks out of the shell, and the snout is pronounced and pointed. The compound eye is large and distinct, the curved potato pulse can be rotated continuously, and there is a single eye between the compound eye and the first antennae. The first antennae under the snout are short and immobile; There are 3 to 4 ventral processes on the dorsal side of the abdomen, the first one is particularly well developed and extends anteriorly.

The posterior abdomen is elongated and gradually narrowed backwards. Thorax 5 pairs, tail forked claw-shaped. The male is small and the dorsal margin of the shell flap is straight.

The snout is short and blunt or absent. Degeneration of the ventral process. The first antennae are long, movable, and have long flagella.

In spring and summer, only females can be seen, and the eggs laid are called "summer eggs", which are smaller, with thin egg shells and less yolk, and can directly develop into adult worms without fertilization. Most of these adults are females and then undergo parthenogenesis. Therefore, it can reproduce in large numbers in a short period of time and is a piece of red, so it is called bloodworm.

Except for a few that live in seawater, it is the most common zooplankton in various freshwater waters and is an excellent bait for fish.

Bloodworms are the larvae of the midge. Silkworms, commonly known as bloodworms, are common benthic animals in freshwater slag deficiency, and mostly live in sewage ditches and drainage outlets containing more organic matter and humus. Bloodworms are generally used as bait, and there are various ways to use them, such as using string hooks to hang bloodworms to fish for bright beams, or hanging bloodworms with hand rods for fishing, and can also be mixed with bait to make "meat sandwich bun" bait, so that the fish can be hooked.

Bloodworms have heme in their bodies, which is why bloodworms are blood-red. There are more than 5,000 kinds of insects known in the world today, and the morphology of the blood-sucking mosquito is basically similar to that of the blood-sucking mosquito that is usually seen.

Bloodworms are widely distributed in various water bodies, and are excellent natural bait for a variety of economic aquatic animals such as a variety of fish, shrimp, crabs, turtles, turtles, etc. For anglers, red flushes are generally used as bait, and they are very popular with fish.

Since bloodworms grow in heavily polluted water bodies and are hosts to many germs, they can also carry dangerous viruses and bacteria, so it is best not to touch bloodworms if you have wounds on your hands.

Bloodworms are larvae of the family Mosquitoidae. Red returnworms are named based on their appearance characteristics because they are red. In addition, they are also known by other names like midges larvae.

The midgel family belongs to the ptera, which is an insect compendium of the phylum Arthropoda. Their growth generally includes egg stage, larval stage, pupal stage and adult stage, among which the larval stage of the midges is also called bloodworm. Their larval stage is relatively long, generally 4 months or even 5 months.

The Rhodophyllum bug is a very common insect that has applications in many places, especially in fisheries. Bloodworms are named based on their physical characteristics, and they also have other names, mosquito larvae. The name is the result of the naming of bloodworms according to the category of bloodworms, as bloodworms are larvae of the family Mosquitoidae.

The midgel family belongs to the class Diptera of the class Arthropoda. In addition to the mosquito family, there are other subjects, such as the common mosquito family, and the mosquitoes that can suck blood are basically in the mosquito family.

Fishing Method:Fishing with bloodworms is generally better than earthworms. According to the fisherman, bloodworms are divided into male and female.

Female worms are smaller and thinner than male worms, and are generally used to make nests or make bloodworm bait, which is cheap but not easy to preserve. (Note that the female bloodworms bought back cannot be stored in water, just wet them with water and spread them on the cotton fabric, and turn the bloodworms back and forth by hand to facilitate contact with oxygen to help them live).

Bloodworms are the larvae of the midge.

Bloodworms are larvae of midges and their mouthparts degenerate and do not suck blood. In the north, it is sold in the flower and bird market. At present, there are about 5,000 species of insects in the family of midges known in the world, which are similar to common mosquitoes, but the main difference is that the antennae are densely covered with fine hairs, like feathers.

Another difference is that its mouth (mouth needle) has degenerated and is no longer capable of sucking. Therefore, we can say that it does not bite. Bloodworms also have a knack for living in a relatively oxygen-deprived environment. Because it has heme in its body, which is why it is blood-red.

Bloodworm breeding methods

It is advisable to choose paddy fields with sufficient water sources and convenient drainage and irrigation as breeding bases, or select places with sufficient water sources to change dry fields into paddy fields. The general paddy field does not need to be transformed, as long as the ridge does not leak and is not washed away in rainy days. The slope that the vermifield is required to have.

Set up a water inlet at the higher end and a high drainage outlet at the lower end, and set up a fence at the inlet and drainage inlet to prevent fish, shrimp and other predators from entering. An annular ditch is dug along the edge of the ridge in the earthworm field so that the water in the earthworm field can be discharged. It should be noted that the medium in the vermifield should be raked flat, so that the depth of the medium should be consistent.

And the inlet and outlet should be set reasonably, so that there is no dead end without water circulation in the field. The distance between the inlet and outlet should be far enough to prevent the feed and fertilizer from being carried away by the water.
