A couple of issues with one of my Buddleia davidii

Hi All,

Several leaves at the bottom of one of my buddleias seem to be covered with a sticky, shiny substance. Anything to worry about? Also getting a few discoloured ones, slightly different shade of green on parts of the leaves. I seem to vaguely remember the discolouration from quite a few years ago, looked into it and found out it wasn't a big problem from what I recall, correct? Mullein moth caterpillars on it, are these issues anything associated with these?

Sorry I can't provide any photos of either ATM, having a problem with my camera!

Thanks,

Nick

 

The shiny stuff on the leaves is probably honey dew.
Aphids are the usual problem on the undersides of the leaves.

Mullein moth caterpillars will probably strip all the leaves if you let them have their way.

 

Thanks @pete! Yeah, having awful problems with blackfly and greenfly this year so might well be honeydew. Ladybirds are gradually coming in to sort the issue out now, so I should see less and less of it, I suppose. I quite like the caterpillars and with 5 buddleias to potentially strip I think it might be too much food for them, but occasional squashing may commence soon if they get greedy...
