Green –  Rare / Uncommon / Scarce   
Taxonomy:   Micro  >> .  . >>  Tortricidae  >> Olethreutinae
Other Name/s: Cowberry Tortrix Olethreutes margindiana
ID Difficulty:  green  – easy to identify, generally distinctive and unlikely to be confused with other species.
ID pointers: Has a net-like pattern over a purplish-brown forewing with darker and leaden grey speckling. At about one half there is a dark purplish-brown cross-band.
Distribution:  (Last record: 16 May 2025 at Chunal Moor )  –  Nationally Scarce B – A species totally restricted to the high moorlands of Derbyshire where Cowberry grows (the food plant) – It seems to prefer undisturbed moorland that has not been burnt and where the moorland has not been heavily managed for grouse. It appears that the species is localised in small colonies on the moorlands where it has been found. I suspect it has been under recorded but as it is so restricted on habitat, I have graded it as uncommon.
Flight Period: May /  June /  –  May and June in the late afternoon and early evening Moth Activity: Cathemeral   – active in afternoon and evening sunshine and occasionally comes to light Photographed: Yes –  Photographed By: Christian Heintzen – Leaf spinnings & larvae  © All Rights Reserved
