Message: <blockquote data-quote="Gavia_immer" data-source="post: 1517531" data-attributes="member: 65934">First of all, thanks for starting the Erebia thread Balkantrek!! :t:Second, I don't know how I managed to skip the links to Cynthia you posted in the previous page, Balkantrek. I downloaded all and I have checked the Chapman's/Escher's/Common one. I found there an ID tip for Escher's/Chapman's that I didn't know :eek!: :eek!: And it works in most of the pics I have checked!!!!It says that the orange lunules of Escher's Blue are bordered externaly with black. This is subtle but it works! I am using pics that are not mine <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /> but extremely good to show this feature. It is amazing. And I would say that in general, Escher's has more black surrounding the orange lunules than Chapman's (in both extremes of the orange lunules).The Chapman's Blue pic was taken by Rafael Estevez, a brilliant Spanish photographer. His photographs of Butterflies leave me open-mouthed.</blockquote>
