Midges: Commonly known as small bites and black mosquitoes, they are the smallest blood-sucking insects in the order Diptera.
Small bites can not only cause skin redness, swelling and itching, but can also lead to infection in severe cases. At the same time, they may also transmit viruses while sucking blood, causing illness in humans and other animals.
Midges are holometabolous insects, with a life cycle that includes four stages: egg, larvae, pupa and adult.
The time required for the life cycle of midges is closely related to temperature. It takes about one month in summer, and usually can reproduce 2 to 4 generations a year, depending on the species and region. Male midges die 1 to 2 days after mating, while female midges live for about a month. Usually overwinter as larvae or eggs.
Female midges lay their eggs in moist places. The eggs are easily shriveled and unable to hatch in dry environments. When the eggs hatch, they will first have a pair of bulges at the thick end of the egg, formed by the forehead of the larvae inside the egg. Break the egg process, crack the egg shell transversely, and drill out the head first. Most of the eggs hatch at the same time, with a difference of no more than half a day.
Midbit bites suck human blood, and the bites often cause local reactions and itching, and even cause systemic allergic reactions. More importantly, they can spread a variety of human diseases.
