Brown –  Significant Record / Very Rare / Vagrant    
Taxonomy:   Micro   >>  Yponomeutidae  >> Yponomeutinae
Other Name/s: Orpine Ermel
ID Difficulty:  amber  – care required in the identification process, as confusion with similar species is likely – quality photographs required.
ID pointers: Overall smokey grey moth with a bright yellow head – darker grey towards the cila and termen.
Distribution:  (First record: 1926 )  –  (Last record: 1976 )  –  This species was discovered new to the British Isles in 1926 on dry limestone slopes on the Derbyshire side of Dovedale. It was later found fairly commonly in Dovedale as an imagine and as a larva feeding on Orpine (Sedum telephium). Seemingly the Orpine has suffered from both overgrazing and over-walking and this moth has not been recorded since 1976. If the food plant can be found in suitable quantities, there is hope that this species may be re-discovered

Bedrock Geology ** indirectly affects moth distribution by influencing the type of habitat and food plants available in an area. In turn, this may affect the types of moths that can thrive, or where they can most likely be found.
