What do a mosquito's shrunken hind wings do?

Steady its flight: called halteres, they beat in time with the wings and work like gyroscopes, sensing every twist and turn.

What do ALL mosquitoes, male and female, drink?

Flower nectar: while sipping it, mosquitoes pollinate some flowers, including a Platanthera orchid whose scent lures Aedes mosquitoes in.

Roughly how many people die from mosquito-borne diseases each year?

Around a million: malaria alone killed about 610,000 people in 2024, and insecticide resistance in Anopheles mosquitoes now threatens progress against it.

Which insecticide, used against malaria mosquitoes in World War II, did the US ban for farm use in 1972?

DDT: Rachel Carson's Silent Spring raised public alarm over it, yet a global treaty still lets countries spray it against malaria mosquitoes.

About how many times a second do male mosquitoes beat their wings?

About 600: females beat their wings more slowly, and surveillance traps play a female's lower flight tone to lure the males in.

In hot weather, about how fast can a mosquito grow from egg to flying adult?

In about five days: yet some mosquito eggs can survive dry conditions for months, hatching only when water finally reaches them.

Why do male mosquitoes often gather in swarms around dusk?

To mate: females fly into the swarm and pair off in mid-air, and once mated, a female usually refuses to mate again.

What does a female mosquito mainly need a blood meal for?

Making eggs: blood supplies the protein her eggs need, so she rests two or three days to digest it before laying, and males never bite at all.

People highly attractive to mosquitoes produce more of what on their skin?

Carboxylic acids: and the pull lasts, since the most attractive people stayed on top when tested again, for several years in one study.

Which colours are mosquitoes visually drawn to after they detect carbon dioxide?

Red and orange: human skin of every tone is dominated by those wavelengths, and filtering them out of the light stopped the attraction in tests.

Engineers have copied a mosquito's piercing mouthparts to design what?

Painless needles: a mosquito's bundle of six fine stylets saws into skin so gently that she can often drink unnoticed.

Which continent has no mosquitoes?

Antarctica: yet the Arctic has mosquitoes whose summer swarms torment caribou herds.

Where do caribou herds often head to escape swarms of Arctic mosquitoes?

Gin and tonic: tonic water began as quinine mixed with soda and sugar to hide its bitterness, and the cocktail is thought to have been born in India.

Amber-trapped mosquitoes really exist, but DNA degrades far too fast to survive tens of millions of years.

The genus name Anopheles comes from a Greek word meaning what?

'Useless': Johann Meigen coined the name in 1818, yet female Anopheles are the mosquitoes that carry the parasites behind human malaria.
