Swarms of ladybirds carrying sexually-transmitted diseases could be on their way to the region.
The insects, known as the Harlequin ladybird, have black wings rather than the common red.
They are flying in from Asia and North America on the mild autumn winds and pose a threat to our native species.
The threat is due to a sexually-transmitted disease they carry called Laboulbeniales fungal disease.
The fungus is passed on through mating or close contact and can infect our native species.
It cannot be passed on to humans and is not harmful to humans in any way.
People have already reported seeing swarms of the insects in the last few days.
In 2009 swarms of ladybirds invaded the north Norfolk coast with thousands covering the area.
The influx was caused by an abundance of aphids, the favourite food of the ladybird.
