Can mosquitoes see things? Why are there mosquitoes in high-rise buildings?

Sometimes we are curious about how there are mosquitoes in high-rise buildings. Do mosquitoes climb stairs to take the elevator? Yes, your guess is correct. The reasons why there are mosquitoes in high-rise buildings may be that, first, mosquitoes enter the elevator at the bottom floor and are brought to the upper floors by attaching to the human body; second, mosquitoes hide in shopping bags, express boxes and other items and are brought to the upper floors; third, they slowly reproduce through the garbage piles on the stairs and climb up layer by layer. Next, let's learn more about what mosquitoes see.

Mosquito flying speed

The flying speed of mosquitoes is between 0.24 meters per second and 1.56 meters per second, with an average flying speed of 0.81 meters per second. The flying speed of mosquitoes is determined by the vibration frequency of their wings, which is generally about 600 times per second.

Mosquitoes belong to the order Diptera and the family Culicidae, and are the most important group of medical insects. Mosquitoes are widely distributed and there are many species. So far, 3 subfamilies, 35 genera, and more than 3,600 species and subspecies of mosquitoes have been recorded worldwide.

Mosquitoes are small insects. The adult mosquito is about 1.6 to 12.6 mm long, gray-brown, tan or black in color, and divided into three parts: head, thorax and abdomen.

Mosquitoes have digestive, excretory, respiratory, circulatory and reproductive systems.

Can mosquito eyes see?

Mosquitoes can see things with their eyes. Mosquitoes have a pair of compound eyes and antennae. Compound eyes are composed of an indefinite number of small eye surfaces, which are generally hexagonal and are the main visual organs of mosquitoes. However, mosquitoes have a relatively sensitive sense of smell, and they mostly rely on their antennae to determine the location of the human body.

Mosquitoes are attracted to photosites, and in their eyes, ultraviolet light is a dazzling and bright light source. The mosquito-killing lamps sold on the market use the principle of mosquito phototaxis, using ultraviolet light to lure mosquitoes and kill them.

In addition to being attracted to ultraviolet light, mosquitoes do not like orange-red light. Orange-red lights can be installed indoors to repel mosquitoes.

Mosquitoes mainly rely on carbon dioxide and infrared rays to find their targets. When people breathe, the mosquitoes' antennae sense the heat source and fly over.

Why are there mosquitoes on high floors?

The reasons why there are mosquitoes on high floors may be that, first, mosquitoes enter the elevator on the ground floor and are brought to high floors by attaching to the human body; second, mosquitoes hide in shopping bags, express boxes and other items and are brought to high floors; third, they slowly reproduce through the garbage piles on the stairs and climb up floor by floor.

Under normal circumstances, the maximum height a mosquito can fly is about 30 meters. Most mosquitoes generally fly below 10 meters, but they can enter high altitudes through various channels.

When mosquitoes climb to higher floors through stairs, they usually do not go to very high floors at once. If they do not find food to replenish on a certain floor, they will move to another location.

Mosquitoes need sufficient water to reproduce, so there will be more mosquitoes on the humid first floor. However, there are mosquitoes on high floors, but the possibility of mosquitoes is relatively small.
