Woodlice

Sorry did'nt read the bit about bore holes. Sounds like a wood wasp grub to me, did you find any grubs? They're quite common round here the grubs are big, over an inch long and the holes they make are about 10mm. The adult looks like a large wasp up to 6cm with quite long legs, the female has a large ovipositor which looks like a sting.

 

Only thing is I think they only feed on conifers, they only eat dead wood anyway.

I think that you have it spot on there crispy. Down side is that the quote left this afternoon. It would have been nice to include the pamphlit along with the quote. I am pretty sure you are right about these holes. My site is only about 50 miles (Straight line) from Milton Keynes.

Having looked at the picture of that nasty wasp.... I dont want to mess with her!

 

It seems that there is no evidence that the moth causes detremental damage to the trees tho.

 

Am I missing something?

Sorrry Bish took a while to get back to the computer.

 

From what i can make out it seems that after the grubs hatch out, in the process of finding food they munch their way through the xylem and phloem. In effect ring barking the tree or cutting off the supply to the roots So dead top or dead roots.

 

We have got some more to fell so i'll let you know what we find.
