Adult tiger mosquitoes are medium sized, black in color with distinctive white stripes. This color pattern is the basis for the name "tiger." The Asian Tiger Mosquito is easy to spot. The mosquito's color pattern consists of a dark black background highlighted with bright white markings. The legs are broadly striped with snow white scales, the thorax has a distinct white racing stripe down its center and the abdomen has incomplete white stripes that appear as lines of bold white dots. The Asian Tiger Mosquito, like most mosquitoes, waves her legs above her head as she attempts to bite. The bright banding pattern on the hind legs accentuates the waving behavior and serves as a forewarning for the pain that will follow. Asian Tiger Mosquito is small. A robust adult female in quest of a blood meal measures slightly less than 1/4" in total length. |
Identification of an Asian Tiger MosquitoAsian Tiger Mosquito are known as tiger mosquitoes due to their patterns of very black bodies with white stripes. Also, there is a distinctive single white band (stripe) down the length of the back. The body length is about 3/16-inch long. Like all adult mosquitoes, Asian tiger mosquitoes are small, fragile insects with slender bodies, one pair of narrow wings with tiny scales, and three pairs of long, slender legs. They have an elongate proboscis (beak) with which the female bites and feeds on blood, while males feed only on plant nectar. Eggs are elongate, usually 1/40-inch long, and dark brown to black near hatching. Larvae (wigglers) are filter feeders that move with an S-shaped motion. Pupae (tumblers) are comma-shaped, appearing to tumble through the water when disturbed. |
Another female Asian Mosquito suck my blood. This time is a mosquito with 3 lice (ticks or fleas). Lice in-turn suck blood from the mosquito which is a tiny amount much less than a mosquito does. Above photo taken on 14 September 2008 at a forest reserve in Tawau Town. |
The tiger mosquito is native to Asia.

Tiger mosquitoes are persistent, moderately aggressive biters. They prefer to feed on the lower legs. The mosquito is very agile and can be difficult to kill with a casual slap. Young children playing outdoors during the early morning or late afternoon in shaded areas are particularly vulnerable to being bitten as they are often sitting or crawling on the ground and, being distracted by play, do not notice the mosquitoes.
The bite of the tiger mosquito is not painful and often goes
unnoticed. Interrupted feeding is common and a female mosquito may bite the same
person several times or move from person to person before the urge to blood feed
is satiated. |
In Asia a mosquito bites can be deadly. Day flying mosquitoes transmit dengue fever and yellow fever. Night flyers bring malaria and Japanese encephalitis. We need to be careful. The first step in prevention is to understand the danger. Anyone suspecting the presence of, or collecting samples of specimens believed to be the Asian Tiger Mosquito in their area should contact: Department of Health. |
