I work hard to not use chemicals in my garden and, as a result, have a large range of insects, (I saw my first ever elephant hawk moth catrerpillar today!), and a great range of flowers.
Having just returned from holiday I was delighted to see some red admiral butterflies enjoying my Buddleia flowers - but disappointed to see that the leaves of this great shrub had been turned into lace doylies!
I have examined the leaves and found nothing. Can anybody tell me:
1) a likely culprit?
2) If this will cause any long term damage to my shrub?
3) Is there a way of stopping this problem naturally (or in a way that doesn't impact my "visitors"?
