New Species - Narrow-bordered Five-spot Burnet

I have had a lot of Six-spot Burnets on site, particularly last year and this year so far. When I get a chance I count the spots but up to yesterday there has always been six of them. For the first time yesterday I counted and only got to five....... What we get here in Monmouthshire is the Narrow-bordered Five-spot Burnet (Zygaena lonicerae) rather than the Five-spot Burnet (Zygaena trifolii)which is thought to be extinct in the county. I am concluding therefore that this is Z. lonicerae (although it is difficult to tell them apart), For comparison I show above the Narrow-bordered Five-spot Burnet photographed yesterday (top) and a Six-spot Burnet photographed last Saturday.
