Roughly how many mosquito species are there?

They are split into two subfamilies: Anophelinae, which carry malaria, and the much larger Culicinae, which carry viruses such as dengue.

How many pairs of wings does a mosquito have?

Like all true flies, the second pair is reduced to tiny balancing organs called halteres.

What do ALL mosquitoes, male and female, drink?

Blood is a female-only extra in many species, taken mainly for the protein needed to make eggs.

How many people do mosquito-borne diseases kill each year, according to Wikipedia?

Nearly 700 million people catch a mosquito-borne illness annually, which is why the insect is called the deadliest animal on Earth.

What are the four stages of the mosquito life cycle?

The first three stages are aquatic; the pupa, nicknamed the tumbler, hangs from the surface by breathing trumpets.

Anopheles mosquitoes can fly continuously for up to four hours and cover how far in a night?

They cruise at only 1 to 2 km/h, slower than a walking human.

Male mosquitoes beat their wings roughly how many times per second?

The wing muscles do not attach to the wings directly; they vibrate the thorax, which flicks the wings.

In hot weather, how quickly can a mosquito develop from egg to adult?

In cooler conditions the same journey can take a month, and some species overwinter as adults in diapause.

How many times does a female mosquito mate in her lifetime?

She is drawn into a dusk swarm of males by their pheromones, then spends the rest of her weeks feeding and laying.

After a full blood meal, how long does a female typically rest before laying eggs?

A female can lay 100 to 200 eggs over her lifetime, repeating the feed-rest-lay cycle each time.

Which mosquito genus lays its eggs in floating rafts?

Anopheles females dap single cigar-shaped eggs with floats onto the surface, while Aedes drop theirs on damp mud to hatch when flooded.

A mosquito larva breathes air through what?

That is why larvae hang just under the surface and dive when disturbed; the pupa switches to a pair of respiratory trumpets.

Which three genera never take blood at all, reproducing on plant food alone?

They are a tiny minority; disease vectors like Anopheles and Aedes cannot lay eggs without a blood meal.

Which two chemicals in exhaled breath do female mosquitoes home in on?

1-octen-3-ol is 'mushroom alcohol'; of 72 odour receptor types on the antennae, at least 27 are tuned to chemicals in sweat.

People with which blood group are preferred by mosquitoes?

They also favour lots of skin bacteria, high body heat and pregnant women, and attractiveness has a heritable component.

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

Skin bacteria turn sweat and sebum into these volatile compounds, which is why odour profiles vary so much between people.

They are also strongly attracted to dark, high-contrast objects against lighter backgrounds.

How many piercing stylets are bundled inside a female mosquito's proboscis?

Two mandibles, two maxillae, the hypopharynx and the labrum; the sawing tips need a thousandth of the force of a needle, so the bite is painless.

Sudden mid-winter thaws in polar regions trick pupae into emerging, then refreeze before they can breed.

One of the earliest animated films, it is also known as The Story of a Mosquito; McCay went on to make Gertie the Dinosaur.

British interests dominated the region for centuries as the Mosquito Kingdom before Nicaragua absorbed it in 1894.

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

Anopheles gambiae is the best-known carrier of Plasmodium falciparum; no other mosquito genus transmits human malaria.

Aedes aegypti, the yellow fever mosquito, has a thorax marking shaped like which musical instrument?

It reflects the miasma theory; the disease was also called ague, paludism and marsh fever.

Who first saw malaria parasites inside human red blood cells, in Algeria in 1880?

The French army doctor won the 1907 Nobel Prize; Grassi's Italian team later showed transmission to humans in 1898.

Which physician proved in Calcutta in 1897 that the malaria parasite completes its life cycle in mosquitoes?

He won the 1902 Nobel Prize and later ran malaria-control efforts in Egypt, Panama, Greece and Mauritius.

Peruvians used it against fever; Jesuits brought it to Europe around 1640 and it entered the London Pharmacopoeia by 1677.

Chinese herbalists had used the plant for 2,000 years; artemisinin combinations became the standard treatment for falciparum malaria.

Carrying one copy of which inherited blood condition gives resistance to malaria without severe anaemia?

One copy of the gene protects; two copies cause sickle-cell disease, a classic evolutionary trade-off in malarial regions.
