Where to see them

Did you know…

  • It carries sleeping sickness; the female gives birth to fully developed larvae, one at a time.

    From Tsetse Fly

  • It is viviparous: it lays no eggs but gestates a single larva inside the uterus and feeds it on a milky secretion produced by a specialised gland, with proteins analogous to those of mammalian milk.

    From Tsetse Fly

  • That strategy gives it a very low fecundity — between eight and ten offspring in a lifetime, against the hundreds of a mosquito — and that is precisely what makes it vulnerable to population control.

    From Tsetse Fly

  • It is a kleptoparasite: in mid-flight it flicks its eggs towards the entrances of solitary bee nests, and the larvae that hatch devour the provisions and the bee's own larva.

    From Dark-edged Bee-fly

  • Its proboscis is rigid and cannot be folded away, so it carries it out in front like a lance, although it is completely harmless and does not sting.

    From Dark-edged Bee-fly

  • Its hovering flight, with the legs dangling and the wings almost invisible, is one of the most recognisable sights of early spring.

    From Dark-edged Bee-fly

  • Its whole cycle from egg to adult can take only 7 to 10 days in ideal conditions.

    From House-fly

  • It feeds by suction and cannot take in solid food.
