Solved What are these eggs? Ladybird?

My first thought was ladybird, and certainly more likely in the site, but the shield bugs are common, so I suggested that as a possible alternative.
Either way- a friend to a garden.

 

Trouble is the harlequin is an invasive species that is a threat to our native ladybirds

 

@DiggersJo I am so sorry I misunderstood you, I thought you were talking about killing our native ladybirds and not the interlopers.

 

The thing is, the harlequin ladybird is here to stay, and as it’s frequently pointed out to us that there is a serious decline of insects in general, then killing for the sake of killing them is not going to be helpful. (I’m really not sure how we sort this problem out. A bit like the problem with grey versus red squirrels, mink, etc).
There are other insects which we have concerns about, certainly, including the hornet/wasp that is killing our bees (forget its name, is it Far Eastern?), but generally, we need to be careful what we destroy. Our eco system is precarious. Without insects, “We’re doomed, Captain Mainwaring”. The biggest predator of all, of course, is Man.

 

The harlequin ladybird is likely to stay, but not for sure. The grey squirrel we need to stop!

 

Grey squirrels do more than just decimate our reds. They damage new tree growth etc too, so it isn't always a single problem that non native species create.
Inevitable, as our climate changes, some species will spread into areas they wouldn't normally be able to survive in, which could create even more problems in future, just as many plants either have to adapt, or they disappear completely. Many of our hilltop alpines up here are now in decline, or have gone, because they can't go any further - there's no more hill left for them to move into.

 

I agree about the grey squirrel, just not sure how it will be achieved as there are so many of them.
It’s certainly a problem we are facing with non native species, but not an easy one to solve (if it ever can be completely).

 

Ladybird eggs are oval and yellow as in @Ladybird4's photo, not round and white as in the original photo and @Loofah's photo.

These are Shield bug eggs.
