About this image

Macrophotograph of a yellow fever mosquito, Aedes aegypti, feeding on a human arm. Female mosquitoes are the ones that bite as they need blood to feed their developing eggs. A. aegypti is a mid-size species with a body length of 4-7mm. It can spread the viruses responsible for Dengue Fever, Yellow Fever and Chikungunya among other diseases. Despite various attempts at control, these diseases have risen 30-fold in the last 30 years. Current efforts are aimed at finding a genetic modification that could prevent the mosquito larvae surviving to the reproductive stage. This image was captured on a Nikon D800 camera and macro lens. The apparent depth of field was extended using a sequence of stacked images. School of Physics, Monash University, Victoria, Australia
