I find that when I wear heavy colored clothes, mosquitoes always bite me. I don't know what the principle is?
Mosquitoes like weak light, and they don't like all dark or strong light. Of course, due to different mosquito species, the intensity of light it likes varies. For example, Aedes mosquitoes are mostly active during the day, while Culex and Anopheles mosquitoes are mostly active at dusk or dawn. But whether they are active during the day or at night, they all want to avoid the strong light. Dark clothes such as dark blue, coffee, black, because the light is dim, suitable for the living habits of mosquitoes, light clothes reflect strong light, have repellent effect on mosquitoes. So people in dark clothes are more likely to be bitten by mosquitoes than people in light clothes.
