Its really weird damage when you look at it overall, its only on the branches/stems on the outer rim and only those that had been tied down always about 7-10cm from top. I have found about 8 or 9 parts that are affected I have only had to take out two tops so far. The rest are strong enough to hold up even with the damage with the exception of 1 which I have taped. These all seem perfectly healthy apart from the area that has been eaten. I have treated it with BT paying attention to the holes. I am still a bit puzzled at this stage but working on the assumption its some kind of slug or caterpillar hence the treatment with BT which is the fourth time so far this season and with each treatment less damage occurring. The caterpillar damage was never huge but I don't want to have my plants continually topped. I have been thinking about this and what would make more sense is something that had to eat its way out after having been laid/injected their previously? Eats its way out and is gone or eats the BT treated plant and dies on exit? The holes are all the same shape main difference is size. When you look at the holes closely it looks like a space has been hollowed out to form a chamber because its very clean and I have not found a bug in any of the few I have had to split open. The chamber ends abruptly and appears to be like a wall The BT seems to have done the trick for the moment

3 downloads Despite the fact it has been eaten it looks fine, there are no eggs or other critters inside the holes. The holes stop abruptly, almost like they left in the middle of dinner, it looks like some kind of cocoon chamber to me but I know nothing about insects

I have not found any new damage since the other day and I have been checking very regularly hoping to see what ever it is..nothing seems to be happening. I will also take the tape off the top that was originally showing signs of attack in another few days and see if this has helped or hindered the recovery. I may need to split the few that need it till they recover suff
