Aphid damage on Buddleja - For RHS

Farway

I have just come across this article from the RHS

https://www.rhs.org.uk/biodiversity/aphids-on-buddleja

You can read all about it on RHS page, but in summary

Buddleja leaves affected by aphids show unusual puckering and discolouration, caused by aphids feeding on the undersides of the leaves. Over time, the damage curls the leaf and can create pale patches that look similar to disease symptoms caused by a virus.

As part of our scientific research, we would like to know where buddleja aphid damage has been seen. If you’ve seen symptoms on buddleja plants, please take photos of the upper and lower sides of the leaves to submit to our survey.

So, MSE gardeners, any spare time to help out on a scientific survey?

For info, here are the pics I've just submitted to RHS survey

I have a walk where there are lots growing wild.
That's where I chose my cuttings from 
I'll make an effort to go along there this weekend.

Lots of aphids around with the long hot spell.

What an interesting link Farway - thank you. I had a good mooch round and have saved some links to read later.

Mine aren't, but as reported elsewhere, my black aphids don't match the RHS's green bugs.

Interesting.  I don't have a buddleja myself but I see plenty of them on my walk to work so I'll keep my eye out

I follow several facebook gardening pages and over the last month or so, I reckon about every tenth post is "why are all these aphids on my buddleja?"
