In the summer, why do mosquitoes like to sting people in black clothes?

Insects have a pair of large eyes on their heads, which occupy almost three-quarters of the head area; these eyes, called compound eyes in entomology, are composed of many individual small eyes. These large eyes can not only distinguish objects but also differentiate between different colors and respond to different intensities of light.

Mosquitoes mostly prefer weak light and dislike total darkness or strong light. Of course, the degree to which mosquitoes prefer light varies depending on the species. For example, Aedes mosquitoes are mostly active during the day, while Culex and Anopheles mosquitoes are mostly active at dusk or dawn. But regardless of whether they are diurnal or nocturnal species, they all prefer to avoid strong light; even the diurnal Aedes mosquitoes only become active around three or four o’clock in the afternoon. So when we wear black clothes, the light is darker, which is suitable for the living habits of mosquitoes; conversely, white clothes reflect stronger light, which has a repellent effect on mosquitoes. For this reason, we are more likely to be bitten by mosquitoes when wearing black clothes compared to white ones.
