This video from the Czech republic says about itself:
Large Copper – Lycaena dispar (Haworth, 1803) – male
Large Copper – Lycaena dispar (Haworth, 1803) is quite common in SE Moravia where I live and expands from there to the North and also to the West.
SE Moravian population is a part of the continuous range from there to the north of Greece and through Russia to the Far East.
In SE Moravia lives its subspecies Lycaena dispar rutilus (Werneburg, 1864).
Dorsal side of male’s pterygia is fire red with goldy yellow lustre and black comma on the front pterygies.
There are three large copper subspecies. The subspecies rutilus, or rutila, of the video lives in large parts of Europe and Asia.
The subspecies batava lives only in the Dutch provinces Overijssel and Friesland.
The third, smallest, subspecies, Lycaena dispar carueli lives only in the Ardennes hills in the south of Belgium.
The Dutch Butterfly Trust reports today about rare butterfly species. They write that on 8 August 2014, a Lycaena dispar carueli butterfly was seen in Limburg province, closest to the Ardennes in the Netherlands. This was the first time ever for this subspecies.
This video from the Czech republic is called High Brown Fritillary – Argynnis adippe – perleťovec prostřední.
In Groningen province, recently a high brown fritillary was seen. Ever since 1976, only a few vagrants of that species had been recorded in the Netherlands. Maybe, this Groningen butterfly came from the Ardennes as well?
