NATURE lovers in Worcestershire have been asked to look out for the arrival of the harlequin ladybird, an invasive species that is a potential threat to Britain's native ladybirds.
Originally from Asia, the harlequin was introduced to North America to control plant pests and became the most common ladybird within 20 years.
They were first spotted in south-eastern Britain in September last year and many sightings have been reported since then.
They are rounder and slightly larger than most British ladybirds and may be black with two or four red or orange spots, or orange with 15 to 20 spots.
When their preferred diet of greenfly is not available, harlequins will prey on native ladybirds and other insects.
A survey supported by Worcestershire Wildlife Trust is calling on gardeners, farmers and wildlife enthusiasts to report any sightings of the harlequins, with the number, date and place
