Is this woodworm or something else?

It looks very much like it Kat but who knows ? there are so many things it could be......

As Amy said Kat it does look very much like woodworm, but there are other insects that can do this too.

looks like woodworm to me.

And to me...

Looks like woodworm to me, but we had a pile of wood at the bottom of our garden many years ago and it was very tiny wasps that drilled holes into the wood. They used to leave little piles of sawdust on the floor.

I think majority think it is woodworm. I was just curious, as I saw lot of trees cut recently and they all looked very healthy to me, but the argument was they were attacked by woodworm. So I was just curious if somebody here can help and say ordeal :))
