Millions of ladybirds invade Britain

Ladybirds clustered in between a window today

An invasion of ladybirds is sweeping across the south east today. Many being spotted are the Harlequin variety, which are a potential threat to numerous insect species.

Many people this morning would have arisen to find the exterior of their houses swarmed by the insects, large numbers of which would have been gathered in between doorways and windows; a sight that can appear slightly unsettling.

“They tend to swarm at this time of year, they are seeking a place to spend the winter” said a spokesman from the Essex Wildlife Trust today.

 

 

A real threat

The harlequin ladybird seems to be dominating this invasion. Originating from Asia, and only colonising Britain for the past four years scientists suggest that it could be threatening more than one thousand native species. Those at threat include other insects, parasites and plants.  It is known as a voracious predator, even preying on the larvae of other ladybirds.

The Essex Wildlife Trust spokesman expressed his concern for the vast amounts being spotted:

“They are incredibly invasive and thought to be detrimental to native ladybirds”

This swarm is certainly quite the spectacle, something of which people should appreciate even though it does carry its deeper concerns.  Observing the sky, trees and thousands of buildings being decorated with small black and red beings is extraordinary, and a rare opportunity.
