Aedes aegypti (US:; from Ancient Greek αηδής (aēdḗs) 'unpleasant' and Latin aegyptī 'Egyptian') – sometimes called the yellow fever mosquito – is a mosquito that spreads diseases such as dengue fever, yellow fever, and chikungunya. The mosquito can be recognized by black and white markings on its legs and a marking in the form of a lyre on the upper surface of its thorax. The mosquito is native to north Africa, but is now a common invasive species that has spread to tropical, subtropical, and temperate regions throughout the world. It was spread to the New World through the slave trade, and is considered to be among the most widespread mosquito species.
Aedes aegypti is a 4-to-7-millimetre-long (5⁄32 to 35⁄128 in), dark mosquito which can be recognized by white markings on its legs and a marking in the form of a lyre on the upper surface of its thorax. Females are larger than males. Microscopically females possess small palps tipped with silver or white scales, and their antennae have sparse short hairs, whereas those of males are feathery. Aedes aegypti can be confused with Aedes albopictus without a magnifying glass: the latter have a white stripe on the top of... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yellow Fever Mosquito sighting in Bangkok on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 127th most-seen of the 245 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March, July, September and December
In those months about 10% of wildlife watchers report a Yellow Fever Mosquito in Bangkok on a given day, against under 5% in January–February, April–June, August and October–November, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Yellow Fever Mosquito sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
26th of 35
Of the 35 cities where we can rate Yellow Fever Mosquito sightings, Bangkok ranks 26th at under 5%. The best odds are in Ciudad Juárez (México, about 10%), León (México, about 10%) and Recife (Brazil, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow Fever Mosquito is recorded against all the insects logged in Bangkok (12 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
