Harlequin ladybird Harmonia axyridis ~ RECORDS PLEASE

So far this autumn the SBRC office has received more reports than previously of Harlequin ladybirds, suggesting that the population explosion predicted two years ago may have happened. It will be useful to know the extent of this across the county.

    The Harlequin is larger than the majority of our native species - approximately 6-8 mm. Our native 7-spot ladybird is similar in size, but the harlequin does not have the same arrangement of spots.

    The Scarce 7-spot are always found near wood ants nests, but the harlequin is not.

    The body is much rounder than most British ladybirds.

    It can be red, orange or mainly black (melanic). Native melanic ladybirds are rarely seen and they are usually much smaller.

    It can have anything from 0 - 19 black spots, which vary in size. If it is black it will usually have 4 red patches.

    The legs of the harlequin are brownish and the hind rim of the underside is quite red. Our other large ladybird, the ‘Eyed ladybird’ has black legs.

    It has a distinctive white mark on its head. Our native cream-spot ladybird always has a reddish fore-body with no white patches.
