A mass of the dotted insects, which are identified by their black wings instead of the common red colour, are infected with the STD Laboulbeniales fungal disease and are believed to be flying over from Asia and North America to the United Kingdom, according to the Mirror Online.

Speaking about the sudden influx of bugs, Professor Helen Roy from the Centre for Ecology and Hydrology in Wallingford, Oxon, said: ''These ladybirds also feed on grapes so they are often found in vineyards which, of course, becomes a problem for wine production.''

However Buglife nature charity have revealed the ladybirds aren't a threat to humans, although they will leave behind a foul smell and stains on furniture and clothes.

A spokesman for the organisation said: ''Large gatherings of them can give off a chemical smell and in centrally-heated houses they may be woken up from hibernation by the warmth and fly around the house.''
