Norway Maple...eaten?

Recommended Posts


Any ideas as to what is/(has been) eating it's way through this maple?

Pictures from phone so not too good...close-up is lowest branch....but you look closely at the second pic you can see it's all over the canopy.

Is the tree doomed?

Caterpillar damage.


Possibly one of the following Moths -


Erannis defoliaria - Motled Umber

Euproctis chrysorrhoea - Brown Tail

Hyphantria curea

Limantria dispar - Gypsy

Operophtera brumata - Winter Moth


Would not expect these to be fatal, but could lead to persistant weakening leaving the Tree open to Armilaria etc


Can you get a picture of the Caterpillar?
