Remember the crisis with those big, bad immigrant ladybirds? The ones that are driving the regular British ladybirds from the land, the grey squirrels of the insect world? Well they've got a problem - sexually transmitted fungal infection:
A team of Scottish scientists have called for the public’s help in mapping the spread of a sexually transmitted fungal epidemic increasingly found in the species.
The insect fungus, which is passed on primarily through mating, has been found infecting the spotted invader.
It's not clear whether this is because the harlequin ladybirds are more rampant, more promiscuous or just most susceptible to the fungus - a chap called Laboulbeniales that leaves little yellow bristles all over the ladybird.
