** Identification write up required
**
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: Endothenia oblongana (Plantain Marble); Endothenia marginana (Bordered Marble)
ID pointers: On average larger than other two Endothenia species. As always, some size differences do occur. Usually shows violet or greyish tones to tornal and basal areas of forewing but these markings can vary considerably, especially the extent of white in the basal area and in the black spots present. An inconspicuous white spot present on the outer margin of the median fascia (this can be hard to discern depending on the amount of markings around it).
Can be determined by hind wing colour: otherwise a CAT 4 Gen Det required.
E. marginana – White with a narrow dark border. E. gentianaeana – Uniformly dark. E. oblongana – Dark, pale towards the base.
Distribution: (Last record: 5 November 2024 at Burton-upon-Trent ) – Uncertain but likely to be found where the food plant exists – Harrison & Sterling list specimens taken from Teasel heads 1929, 1981, 1982, 1983. DaNES – a record from Hall Dale Quarry 9/7/2002 & a record from Swadlincote 30/5/2005 – both refer to adults reared from seed heads. NBN atlas one from Calke Park 1969.
Larva off teasel Burton-on-Trent 5/11/2024.

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.
