Thanks for the replies to my question. The tree is in Tiverton in Devon and 
so I think that goat moth could well be present there. I've told the gardener 
and he's excited by the discovery, and so the tree is going to be retained.

Best regards,

Ben

Hi Ben,

I agree with Stephen that Cossus cossus is the likely suspect, but I'm no 
lepidopterist.

Great habitat find! Goat moth is a UK BAP: Priority species, nationally 
scarce B.
The cats are huge (100mm long) and smell like goats. The cats secrete sap 
wine that other insects drink to get drunk.
The pellets are the frass.
The hole was probably a woodpecker, note the two peck marks above the hole.
Leave the tree alone and be careful where you walk/push the lawnmower/dig 
the garden as they will crawl along the ground looking for somewhere to 
overwinter beneath the soil.
Kind regards,
Ben Oates

That looks to me like a hole made by a woodpecker or some other creature
that's trying to get in, rather than an insect trying to get out. I'd
expect an exit hole to be neater.
And what's called frass looks almost pellet-like; more like insect eggs
or something...??
Not at all sure what might be going on but it looks interesting

Hi all,

I've just been sent some pictures by a client of exit holes from the 
trunk of a rowan and frass at the base. It does look distinctive but I 
can't find it in any of my books. I've attached the photos, can anyone on 
the forum suggest what may have caused this?

Thanks in advance,

Ben
