CATDOLL : CATDOLL: The lifespan of a fly

1. Lifespan of flies

Under normal circumstances, the lifespan of a fly is generally about one month, but in lower temperatures, its lifespan can be extended by 2 to 3 months.

Flies are completely metamorphosed insects with strong reproductive capacity. Their life cycle can be divided into four stages: egg, larva, pupa, and adult. Common ones include houseflies, big-headed golden flies, city flies, green flies, and flesh flies. They mostly live in places rich in feces, garbage, and organic matter. The diet of flies is very complex. They are omnivorous flies and can feed on a variety of substances. They are also good at flying, with a flying speed of 6-8km per hour and a maximum flight speed of 8-18km per day and night. Flies can spread 50 diseases, among which the important diseases that affect livestock and poultry farming include avian influenza, foot-and-mouth disease, and coccidiosis. Usually, we should do a good job of environmental hygiene, disinfect regularly, and properly handle and remove residual garbage.

2. How many days can a fly live?

[Lifespan of flies]

A fly can live for about a month in midsummer. But in low temperatures, its life span can be extended by 2 to 3 months. When the temperature is below 10 degrees, it can hardly move and its life span is longer. The adult life span of a common fly is 15 to 25 days. If its larval and pupal stages are included, its life span is 25 to 70 days.

Let's talk about the life of a fly. 1. Adult

The body is 5 to 8 mm long, gray-brown, with hairless, dark red compound eyes. The forehead width of male flies is 1/4-2/5 of the eye width; the forehead width of female flies is almost equal to the width of one compound eye. The antennae are gray-black, short and flat, with short antennae and thick base. There are feathery hairs on both sides of the dorsal and ventral sides, all the way to the tip of the awn, and the lower whiskers are brown-black. The mouthparts are licking and sucking. A thick and short beak can be seen from the outside, which consists of three parts. The base beak is inverted cone shape, the middle beak is thick and short and tubular, and the terminal beak is well developed and divided into two petals, which are called labellums; the beak can be freely extended. There are 4 black longitudinal stripes on the mesothorax shield, and there are cilia in the central depression of the pronotum side plate. There are no tufts of setae before and after the ribs on the axillary petals, and the lower side pieces are hairy in front of and below the posterior valve. The wings are transparent, the wing veins are brown-yellow, and the base scales of the front edge veins are yellow-white. The end of the fourth longitudinal vein is sharply bent forward to form an angle, and its end is close to the end of the third longitudinal vein. The legs are black with grayish-yellow powder. The abdomen is oval and yellow, especially on both sides of the base. There is a wide black vertical stripe in the middle of the abdomen, and the first abdominal plate has cilia. Flies generally have 6 legs (3 pairs). The front pair is equivalent to the forelimbs of mammals such as humans, kangaroos, monkeys, bears, and pandas. The back two pairs are supporting and exerting power thighs, which are equivalent to the hind limbs of mammals such as humans, kangaroos, monkeys, bears, and pandas.

2. Eggs

The eggs are banana-shaped, about 1 mm long, milky white, with two ridges on the back of the eggshell, the thinnest part is between the ridges. When the eggs hatch, the eggshell cracks here. The eggs are often laid in pieces.

3. Larvae

The larvae are commonly known as maggots. They are legless. The pharyngeal bones, posterior spiracles, posterior spiracles, and small protuberances at the end of the abdomen are common features for classification and identification. There are three instars in the larvae: the first instar larvae are 1-3mm long, transparent in color, without anterior spiracles, and only one posterior spiracles; the second instar larvae are 3-5mm, milky white, with anterior spiracles and two posterior spiracles; the third instar larvae are 5-13mm long, milky yellow, with anterior spiracles and three posterior spiracles, cylindrical, and gradually tapering from the middle to the front. The head is small, the mouth is hooked and claw-shaped, and the left and right are asymmetrical.

4. Pupa

The pupa is barrel-shaped, encircling the pupa, about 6.5 mm long, yellowish-white at first, gradually darkening, and finally chestnut brown, with a pair of pupal spiracles between the 1st and 2nd abdominal segments.

 Factors that affect the life span of flies include temperature, humidity, food and water. The best temperature is 25℃～33℃ and the air humidity is 60%～70%.

Female flies live longer than male flies, with a lifespan of 30 to 60 days; under laboratory conditions, it can last up to 112 days. In low-temperature wintering conditions, flies can live for half a year.

Usually 7 days

4. How long is the life span of a fly?

Flies and vibrating gyroscopes

Flies can fly for hours without landing, and can fly at speeds of up to 20 kilometers per hour. They do not need to glide, and can take off quickly at an angle of 30 degrees to the ground. They can make sudden stops in the air, make sharp turns, and ascend, descend, and land very quickly. Scientists have discovered that there is a pair of small wings behind the wings of flies.

A fly can live for about a month in the midsummer. But in lower temperatures, its lifespan can be extended by 2 to 3 months.

, below 10 degrees, it can hardly move, and its life span is longer

It also depends on you

You let it die.

The life span of male flies is generally only 7 days, while the life span of female flies is generally 15 to 25 days.

The red-headed fly still lays a lot of eggs at 30 days old
