How long can flies live?

Question 1: How many days can flies live? In midsummer, a fly can live about 1 month. But at low temperature, its life can be extended by 2 to 3 months, and it can hardly move below 10 degrees, and its life is longer. The life span of an adult fly is 15 ~ 25 days, which is 25 ~ 70 days if the larval stage and pupal stage are counted.

Question 2: How long does it take a fly from birth to death? How long can flies live? 10 minute A fly can live for about 1 month in midsummer. The life span of an adult fly is 15 ~ 25 days. If the larval stage and pupal stage are included, the life span is 25 ~ 70 days.

The optimum temperature for flies is 27℃ ~ 30℃. The food temperature required by fly larvae is 30 ~ 35℃ ... details >;

Question 3: How many days can flies live?

The life span of a fly can reach about 1 month in midsummer. But at low temperature, its life can be extended by 2 to 3 months, and it can hardly move below 10 degrees, and its life is longer. The life span of an adult fly is 15 ~ 25 days, which is 25 ~ 70 days if the larval stage and pupal stage are counted.

Say the life of flies, 1, adults.

Body length is 5 ~ 8 mm, grayish brown, compound eyes are hairless and dark red, and the forehead width of male flies is1/4-2/5 of the eye width; The width of the female fly's forehead is almost equal to the width of a compound eye. The antenna is gray-black, short and flat, the antenna awn is short, the base is thick, and there are feathery hairs on both sides of the back and abdomen, reaching the tip of the awn, and the next one must be brown-black. Licking mouth shape, the appearance can see a short beak, which consists of three parts. The base beak is inverted cone, the middle beak is tubular, and the end beak develops into two petals, called lip; The beak can expand and contract freely. There are four black longitudinal strips in the middle chest shield plate, cilia in the central depression of the front chest side plate, no bristle tufts in the front and rear ribs of the axillary flap, and hairs in the front and rear lower side plates of the rear air valve. The wings are transparent, the veins are brownish yellow, and the scales at the base of the main veins are yellowish white. The end of the fourth longitudinal vein bends sharply forward at an angle, and its end is close to the end of the third longitudinal vein. The feet are black with grayish yellow powder, and the abdomen is oval and yellow, especially on both sides of the base. There is a wide black longitudinal strip in the middle of the abdomen, and the first web of the abdomen has cilia. Flies generally have 6 legs (3 pairs). The first pair is equivalent to the forelimbs of mammals such as humans, kangaroos, monkeys, bears and pandas. The back two pairs are thighs, which are used for support and strength, equivalent to the hind limbs of mammals such as humans, kangaroos, monkeys, bears and pandas.

Step 2: eggs

Eggs are banana-shaped, about 1mm long, milky white, with two ridges on the back of the eggshell, and the thinnest between them. When the eggs hatch, the eggshells crack here, and the eggs are often produced in pieces.

3. Larva

Larvae, commonly known as maggots, has no feet, and its craniopharyngeal bone, posterior flap, posterior flap fissure and terminal ventral nodule are common features of classification and differentiation. Larvae * * * 3rd instar: 1 instar larvae are 1-3mm long, with transparent body color, no anterior lobe and only 1 fissure in the posterior lobe; The second instar larvae are 3-5 mm, milky white, with 2-lobed anterior and posterior petals; The third instar larvae are 5 ~ 13 mm long, milky yellow, and the front and rear petals are 3-lobed, cylindrical and gradually taper from the middle to the front. The head is small, the mouth is hooked and claw-shaped, and the left and right sides are asymmetrical.

4. Pupa

The pupa is barrel-shaped and surrounds the pupa. It is about 6.5 mm long, yellow and white at first, then dark, and finally chestnut brown. There are 1 pairs of pupa petals between 1 and 2 abdominal segments.

Question 4: What do flies eat to sustain their lives? How long can they live? The feeding habits of flies depend on their species. There are those who specialize in nectar and plant juice, and those who specialize in cannibalism, animal blood or animal wound blood and eye and nose secretions. Common houseflies, Chrysomya megacephala, Lucilia sericata, Calliphora, Hemp flies, etc. belong to omnivorous flies, that is, organic substances in human food, livestock and poultry excreta, kitchen waste and garbage are widely eaten. They have a strong preference for the taste of sugar, vinegar, ammonia and fishy smell. According to the research, if only the female flies are provided with water, sugar and carbohydrates, although they can grow, their ovaries cannot develop and lay eggs; Only by feeding protein with food or a variety of amino acids can you lay eggs normally. If female houseflies are fed with royal jelly, the prophase of oviposition can be shortened and the amount of oviposition can be increased.

An important ecology of flies is omnivorous. They bite and feed in their habitats. Someone once found 76,400 fly maggots and pupae in 1.5 square meters of pig manure! Protein in animal feed, plant feed and even microorganisms are all nutrients that fly maggots like to ingest. The quantity, quality, fermentation temperature and even water content of food are directly related to the development effect of fly maggots. The 3rd instar fly maggots stop feeding when they mature, and often leave the breeding ground at low temperature and humidity of 15 ~ 20℃ and drill into the nearby loose soil to pupate. Someone once found thousands of pupae of houseflies in cracks in the damaged concrete floor of a brewery.

Question 5: How long can flies live if they are kept in a house without any food? It should be about 7 days to 12 days, depending on the temperature and humidity. Test 1: Time: 18 On July 8th, summer, the whole screen window of my house was sealed and ventilated, and the experimental subjects were ***9 flies (I was not sure whether I was full before). By the 26th, except one, I had killed them, and all the others died of natural causes.

Question 6: flies can die for a few days without eating or drinking. Usually we can't see what flies eat. So I can't see it eating every day. In fact, flies will not starve to death if they don't eat for a week. But it also has no ability to fly very far. You will eat it. Eat too much and then continue to fly.
