Anal gills of a mosquito larva. Light microscope footage of the anal gills of a mosquito larva. Mosquito larvae are aquatic. The anal gills are structures found on the anal segment at the end of the larva's abdomen, and arise from a thin membrane around the anus. They are thought to be involved in osmoregulation, the maintenance of correct concentration of fluids and electrolytes.
