[Image] Nit on human hair Kevin Mackenzie

« Scanning electron micrograph of a nit or head louse egg (coloured green) attached to a strand of human hair (coloured brown). Head lice feed on human blood and live in close proximity to the scalp. Female lice lay eggs in sacs that attach firmly to individual strands of hair near the base of the hair shaft. Most will hatch within seven to ten days, and the newly emerged immature louse (nymph) will then need to feed on blood to survive. The width of the image is 1.5 mm. »
