How Do Mosquitoes Make Their Living?
WouterAmong the many insect pests, mosquitoes are a menace, because they transmit diseases, including malaria and encephalitis. They are short-range flyers that can reach speeds of one to 1.5 miles per hour. They are attracted to human blood because it contains protein, which helps to develop eggs.
Mosquitoes make four stages of development: eggs, larvae, pupae, and adults. Some species lay their eggs in moist soil, while others lay them in stagnant water. Many mosquitoes are active during the day, while others hibernate during cold weather. Some species also form mating swarms.
Female mosquitoes lay eggs in moist soil or in water collected in tree holes. They deposit up to three groups of eggs, which are usually white in color. The eggs usually hatch in one to three days, but can lie dormant for months or years.
After laying the eggs, female mosquitoes enter the pupal stage. The pupa, also known as a tumbler, is an aquatic creature that floats around in the water. It has a semi-transparent exoskeleton.
After five days, the larvae change shape and become less active. They molt several times. When they reach the pupae stage, they are a twitching mass, hanging upside down from the water’s surface. They breathe through special appendages called siphons. Their abdomens are specialized for digestion and food gathering.
When a mosquito bites, it injects saliva to aid in blood flow. The saliva may contain pathogens. It also contains an anticoagulant, which helps ensure a smooth blood flow.
