Sucking blood is risky business, at least for the female mosquitoes that need

those nutrients to nurture their developing eggs. Not only do these bugs have to find a

suitable blood donor, but once they've had their fill, they have to be able to escape

undetected to avoid the big swat.

How they finesse this stealthy departure has just been revealed in the Journal of Experimental Biology.

Feasting on an unsuspecting mammal can double a mosquito's body mass.

So how does a fully loaded female heave that added bulk off the skin of her host

without triggering its pressure

sensors and bringing on that fateful slap. To find out, Florian Maures, the Vageningen

University in the Netherlands and his colleagues, used cameras that record 13,500 frames per second

to capture the take-off maneuvers of 63 blood-fed malarial mosquitoes.

What they discovered is, when it comes to a soft yet speedy getaway, for female skeeters, the wings the thing.

With a wing-beat frequency of about 600 beats per second, the insects are able to lift themselves lightly off their host.

That approach is the opposite of the one favored by most other winged things, says Maura's.

Most flying animals, when they take off, like birds or fly, for example,

they first use their legs to push off very hard,
