How can mosquitoes see in darkness

One of the most powerful clues they follow is carbon dioxide. Insect smell detectors, known as olfactory receptors, are highly developed allowing the mosquito to indulge very particular tastes: blood type and the range of bacteria on the skin provide the perfect bouquet. They can even distinguish between different types of perspiration. Much of what makes us particularly desirable is inherited, although alcohol does seem to attract them.

Post as a guest Name. Even among humans, increased CO2 levels are a great way to track human beings. During disaster relief, crews use CO2 detection to find human beings buried beneath the rubble. CO2 is also how mosquitoes detect us. They can detect it even if we are wearing heavy clothing or blankets. Mosquitoes have highly-tuned smell olfactory receptors. To prove this, one experiment placed mosquitoes in a wind tunnel.

The scientists injected plumes of CO2 into this tunnel to imitate human breath. Mosquitoes are also able to detect other signs that a human is nearby. They also use sight to detect a suitable host.

The visual cues take over and draw the mosquito even closer to the human host.
