Any ideas anyone Thanks Tom I was just about to post something similar, but I knew exactly what was causing the holes - Leafcutter bees. Google search for Megachile - loads of info around. They're lovely little non-agressive creatures, and they are apparently stunningly good pollinators. We had one last year, nesting in a small hole in the mortar. This year I was more prepared - there's a palatial block of iroko screwed to the back wall with about 60 holes drilled in it (5 & 8mm, about 15cm deep) & a bunch of canes under a sloping "roof". There'd been a little bit of interest from a few bees about 2 weeks ago, but then things went quiet. I was beginning to dispair, when today I saw 3 different leafcutters popping in and out of the holes with bits of leaf. Last year they cut holes out of either the philadelphus or the hibiscus - can't remember which. This year, couldn't find any evidence. Roses intact. No holes in the bean leaves. Then I looked at a small tub that I'd stuck some peas in... bingo! holes everywhere. A smoking gun if ever I've seen one.... Enjoy them whilst they're around - the amount of damage they do is small compared to their benefit. cheers Richard -- Richard Sampson email me at richard at olifant d-ot co do-t uk |

... snip Thanks, I was not planning to do anything about them as the damage is negligable, I just wondered what it was, as the holes are very symmetrical and I could think of no insect that would do this. Tom Glad to hear it! They're amazing things if you can catch them at work - have just wasted the best part of 2 days watching "ours".... funny thing is, the two roses we have are completely untouched. the peas (but not the sweet peas) and a fuscia (right down at the other end of the garden) now look like a fully interlocking jigsaw puzzle! Fussy things, bees. cheers Richard -- Richard Sampson email me at richard at olifant d-ot co do-t uk |
