What do greenflys do in the winter?

Answer 1

They lay eggs with a very tough coat to help the eggs survive in the cold. Then the old Greenfly die and the new, hatch out of the eggs in the spring!

But ladybirds feed on greenfly so the ladybirds have to hibernate in cracks of the bark and under dead leaves.

Answer 2

Laying their last generations of eggs for the year or overwntering in the soil is what green flies [Lucilia sericata] do in winter. The exact activity depends upon the life cycle stage. Eggs may be laid on dead and decaying organisms and in garbage or manure. When they emerge from the eggs, the larvae ultimately burrow into the soil in preparation for the pupal or chrysalis stage.

Green flies lay eggs within hours of the death of a living organism. The presence of the different green fly stages allows forensic science to give accurates dates on deaths that occur in the wild.

Answer 3

Green flies survive the winter by trying to find warm shelter. Many of them die but the ones that do survive start to reproduce in the spring.
