What is a mosquito proboscis?
Quick Answer
A mosquito proboscis is the long mouthpart used to pierce skin and feed on liquids. In female mosquitoes, it is adapted to draw blood from hosts.
The Full Story
The mosquito proboscis is not a single straw-like tube but a bundle of specialized mouthparts working together. In female mosquitoes, it includes structures that pierce skin, locate blood vessels, and draw up blood. Males do not feed on blood; they usually drink nectar and other plant liquids. Female mosquitoes use the protein and iron from blood to help develop eggs in many species. Mosquitoes are medically important because some species can transmit diseases such as malaria, dengue, Zika, yellow fever, and West Nile virus.
