Harlequin Ladybird

Harlequin LadybirdHarlequin Ladybird

Latin name: Harmonia axyridis

The notorious Harlequin Ladybird is a relatively recent arrival in Alderney from Western Europe, moving north as the climate grows warmer. It is a vividly-coloured ladybird (it is also known as the Multicoloured Asian Ladybird) and has a very variable appearance, which can make it difficult to tell apart from our native ladybirds. However, it is usually bigger, and the most common forms in Britain are orange with 15-21 black spots or black with 2 or 4 orange or red spots.

Its habitat is very diverse and it has a much wider food range than native ladybirds as well as a longer reproductive period. With its voracious appetite, adaptability, lack of known resident parasites and rapidly spreading population the Harlequin Ladybird can easily out-compete our native ladybird species and is the probable principal cause of their decline.
