Thanks William, much appreciated!
Yes, I can see the flaws in my strategy and I realise the beetles won´t be easily fooled...
However, right now they seem to be hiding. I think the cold weather has somewhat disturbed their life cycle. Two weeks ago I spotted and killed loads of them, all plainly visible on the martagon stems. This weekend I found only two, buried in the upper surface of the soil. And there are barely any new eggs. I´m sure the beetles bide their time and eventually will come back, but the lack of eggs might just be a sign that the much feared larvae production won´t be as grand as last summer...
