The living habits of flies

Flies are insects that are active frequently during the day, have obvious phototaxis, and live at rest at night. Their activities are greatly affected by temperature. They can only crawl at 9-10 ℃, fly at 12 ℃, feed, mate and lay eggs at more than 15 ℃, and are especially active at 30-35 ℃. Let's take a look at the living habits of flies.

Mating

Flies have the physiological characteristics that once mating can lay eggs for life. at a suitable temperature, males and females can sexually mature and mate 18-24 hours after Eclosion and 30 hours after Eclosion, and the mating time is usually between 5:00 and 7:00 in the morning.

Oviposition

The peak spawning period of flies is from 17:00 to 19:00 every day. The length of the pre-spawning period (that is, the time from Eclosion to the first spawning) of female flies is closely related to the ambient temperature, and their fecundity is amazing. According to the most conservative estimate, each female fly can produce 200 offspring, and the total number of flies that need only 10 generations of reproduction will reach 20 billion.

Food habit

The feeding habits of flies depend on their species, some specialize in sucking nectar and plant juices, some are addicted to human, animal blood or animal wound blood and eye and nasal secretions, while the common houseflies, big-headed Chrysophora, Mercerized green flies, Calliphoria and sesame flies belong to omnivorous flies, that is, they widely consume human food, livestock and poultry secretions and feces, kitchen leftovers and garbage and other organic matter. It has a strong tendency towards sugar, vinegar, ammonia and fishy taste.

Development

Flies are biologically typical completely abnormal insects, which need to go through four stages: egg stage, larva stage, pupa stage and adult stage.

Life span

The factors affecting the lifespan of flies are temperature, humidity, food and water. The best temperature is 25-33 ℃ and air humidity is 60-70%. The adult lifespan of ordinary flies is 15-25 days, and if larval and pupa stages are included, the lifespan of females is 25-70 days. Females live longer than males, with a lifespan of 30-60 days. Under low-temperature overwintering conditions, flies can live for as long as half a year.
