Etymology
Origin of mosquito
First recorded in 1575–85; from Spanish, equivalent to mosc(a) “fly” (from Latin musca ) + -ito diminutive suffix
Explanation
A mosquito is a tiny stinging insect that leaves an itchy welt on your skin. Between its annoying bites and its ability to spread disease, the mosquito is not the most popular of insects (unlike the fair ladybug). Male mosquitoes feed on nectar and live only a few days, while females need to feed on blood in order for their eggs to develop and be laid. Female mosquitoes, therefore, can be a nuisance on summer evenings, and can even be downright dangerous in tropical areas where they often spread diseases like malaria. In Spanish, mosquito means "little gnat," from mosca, "gnat or fly."
