Harlequin's

Hi Richard, is it proven that Harlequins are harmful to our native species. I often see huge numbers of 7 spot with some 10-spot and 14-spot all happily munching in the same patch of vegetation as Harlequins. Bad news for aphids and the like but I haven't seen a reduction in the native species.

Not known

Hi Chris, they certainly compete for food and at lean times will eat other insects eggs (including our native ladybirds)but as far as I can find out this is still very much in debate as to how much damage is being caused, from my own personal experience, for every one harlequin I see about a hundred natives. Especially so far this year, my area is jumping with 7 spots and I am seeing 14 spots everywhere I turn. I only saw one the whole of last year! I have also seen a huge jump in native species in my garden compared to previous years and only two harlequins. It looks like its going to be a bumper year for all ladybirds.

Regards

-Richard-

22 spot

Thanks for that Richard and I would agree it seems a bumper year for ladybirds if not dragonflies. The only one I do not see much of is the 22-spot but I'll keep searching. Regards Chris
