Help! What’s this? 🙀

My beech tree has a weird condition.

Both sides of the leaves are very sticky.

On the underside of the leaves there is fluffy white stuff.

A plant ID app has identified it as something mildew (I can’t remember)

But it moves!
It’s lots of tiny fluff white bugs.

Please help, wise women (and the occasional man) of Gransnet 🙏

If you zoom into the second picture at the pointy end of the leaf, you can see the bug very clearly.
It couldn’t half shift

I think it’s beech woolly aphid which is a sap sucker, hence the sticky leaves.

It shouldn’t cause any lasting damage and hopefully will be taken care of by whichever birds like eating them.

Oh thank you merlot!
I could hug you 🤗

Somebody else might come along and tell you it’s something different though. 😂

No, that really sounds right
1) it’s on a beech
2) it’s woolly
3) it looks just like an aphid

I seem to have similar bugs on my (smilenot so little) nut tree, so presumably they attack other species as well.

We had these on our beech hedge every year. I found myself worrying at this time of year every year but the hedge didn't seem to mind too much and thrived. The blue tits loved them!

I didn't notice them moving on to anything else - there were plum and cherry trees amongst the hedge and they were unaffected. The aphids occasionally strayed onto the apple trees but didn't stay.

Thanks lixysmile
That’s very reassuring

I get wholly aphids on the old apple tree - but probably a different type, as they appear in any crevices on the trunk and branches, not on the leaves.

Hetty does sap come out of trunks too?
Perhaps that’s why they are there
