I just popped over from your mention in the other thread and in doing so was wondering if they were going to be brown hairstreaks. A beautiful butterfly when the sun catches the orange patch on the wings. First one I ever saw was in Steyning in Suffolk I think and again in Surrey. Were the bushes blackthorn? Hope they hatch ok.

As many will be aware trimming will trim off BH eggs. Otoh, if left untrimmed the blackthorn will lose vigor. So, all farmer need to do is to stop trimming hedges every year*. You can even get paid to do that - it's win win.
So why don't all farmers do that? It beats me.
*it's not just about trimming because, even alternate years trimming, means you get a line in a hedge where it is topped to every time. In the end a hedge like that becomes a series of stumps.
The answer? Hedge laying. And you can get paid to do that too! Win, win, win.
