German researchers have discovered the biological keys to the success of an invasive species, wreaking havoc across Europe and the US,

The Asian ladybird was originally brought in to control aphids in greenhouses.

But it has escaped and is increasing uncontrollably across Europe, wiping out native species.

The alien is winning, say scientists, because its body fluid contains a parasite toxic to other insects.

1. Ladybird, ladybird fly away home,

Ladybird, ladybird fly away home,
Your house is on fire and your children are gone,
All except one,
And her name is Ann,
And she hid under the baking pan.
