Dark Clouded Yellow

This is an specimen of Colias croceus with opened wings. In the wild I have always found them either flying very fast or sitting with their wings closed. Unfortunately the only way I had an opportunity to photograph one with wings opened was in this spotting where the poor butterfly had been run over by a car and was dying.
It seems to be a male, given the description in Wikipedia.
For more info in the species you can visit my other recent spottings, some of them in the same area.
