Harlequin Ladybird
I have several hibernating masses of ladybirds, about 90% of them are harlequin ladybirds. Over the last few days in the garden I've also come across several harlequin ladybirds and just 1 native 7 spot ladybird.
A thought occurred that maybe I should be destroying the harlequin ladybird to help our native species. As a bit of a softie I don't think I actually could (would be quilt ridden!!) but wondered what people did with their's?

I think nearly all of the ladybirds in my garden are harlequin ladybirds and they're so widespread that I could never make much of a dent in the population so I just leave them. They also do a brilliant job of eliminating aphids from the plants!
I leave them. I think it's a battle lost.
I agree B3 - they're here - we're not going to be able to exterminate them, and at least they eat aphids.
If they do kill off the native ladybirds, and we try to kill off the Harlequins, we'll be over-run with aphids.
I leave them alone to get on with what they're good at.

I have just found these larvae on my blackcurrant bush. Are these harlequin larvae do you think? They're on a particular bush that looks as if it's suffering from aphids . It's the first time I've seen these larvae so I'd appreciate anyone's thoughts / advice!
they'll eat your aphids
they're here to stay
I agree with Nut :-)
We've got plenty of Harlequins here on our roses ... they're certainly keeping the aphids down
Thanks for so many swift replies! The link sent by Chrissie B was very helpful as the larva of H.axyridis shown there looks pretty much identical to the photos that I posted. So - as it IS a Harlequin, the question is whether to spray the blackcurrant bushes and hopefully kill both the aphids and the invasive ladybird larvae all together - or let the ladybirds do my job for me and survive to increase their species ... thoughts??

The less spray you use, the better for wildlife in general. All ladybirds and the bluetits and co will eat aphids but you'll never achieve a balance if you kill parts of the food chain. and remember that's your food crop you're spraying poison onto
