a fairy tale. a fable. an allegory...

"The female of a mosquito lays 30-150 or even 280 eggs every 2-3 days.
For egg production mosquitoes need blood,
that’s why the oviposition cycle is in direct proportion to the consumption of blood.
In many species, the female needs to obtain nutrients from a blood meal before she can produce eggs, whereas in many other species, she can produce more eggs after a blood meal.
Both – plant materials and blood – are useful sources of energy in the form of sugars, and blood also supplies more concentrated nutrients, such as lipids, but the most important function of blood meals is to obtain proteins as materials for egg production.”
