The Harlequin Ladybird

News Update from The Harlequin Ladybird Survey website (UK) 

Why are there very large numbers of ladybirds this autumn? 

They are likely to be harlequin ladybirds, an alien species that is spreading fast in the UK. Harlequins are active later in the year than most other ladybird species. In autumn they gather in large groups at overwintering sites, which are often in or on buildings. They leave chemical traces that attract others of the same species to that spot. They do not normally breed indoors and should leave buildings in the spring.

The Harlequin has been reported from Co Down and breeding populations reports from Cos Carlow and Cork.

the most invasive ladybird on Earth.

A new ladybird arrived in Britain in the summer of 2004 called the Harlequin ladybird (Harmonia axyridis)

It is also known as the Multicoloured Asian Ladybird and the Halloween Ladybird. 

It has already invaded much of northwestern Europe

It was introduced to North America in 1988, and is now the most widespread ladybird species on that continent.

The harlequin ladybird (Harmonia axyridis) has a very variable appearance!

The Harlequin ladybirds are most commonly found on deciduous trees, such as lime, sycamore and maple, and on low growing plants such as nettles. They will also inhabit reedbeds, coniferous woodland and crop systems.

Harlequin ladybirds feed most commonly on aphids, but also feed on scale insects, adelgids, eggs and larvae of butterflies and moths, many other small insects, including other ladybirds, pollen, nectar, and sugary fluids, including honeydew and the juice from ripe fruits.
