Native ladybirds are quite harmless and are actually beneficial in the removal of aphids. But this popular bug is now being threatened by the Harlequin Ladybird, a voracious invader from Asia. The Harlequin Ladybird is one of the most invasive insect species in the world. It may have taken the Grey Squirrel 100 years to spread throughout the UK, this ladybird managed it in just 10 years. It was introduced to the United States in the 1980s to deal with the aphid population, but quickly spread. Its arrival here in 2004 was probably accidental, blown over from Europe where it had been introduced, again for aphid control.

The Harlequin Ladybird doesn't stick to one type of food, so once it has worked through the aphids it will turn its attention to the eggs and larvae of other ladybirds, moths and butterflies. They easily out-compete our native ladybirds for food, which is why they are now very scarce.
