Harlequin Ladybird

Apparently quite a few of our native species of ladybird are being effected by a none native species called the Harlequin.

Some of the larger species like the seven spot don’t seem to be effected at the moment. This is probably mainly due to the fact that they both frequent different habitats.

One of the reason the Harlequin seem to be doing so well, is their chemical defences are

more toxic than our native species. That mean’s birds will stay away from them and target our more palatable native ones.

The Harlequin Ladybird will also eat the lava and eggs of other ladybirds and insects.  In fact their presence here is effecting about 1000 UK species of insects in a detrimental way.  It is the most evasive ladybird on this earth!

 

They were brought over to Europe due to their appetites for Aphids. but we know that they are not to fussy what they eat.

It is a very attractive ladybird, but the cost of it being here is to great.
