Which Sulfer?

Moved
Moved from Sulphurs.

Colias eurytheme
This one is pretty typical of the species. The shape of the wings (relatively broad and angular with the outer margin of the front wing straight or even a bit concave in the middle), the "smooth" look, the orange (noticeable on the front wing, and probably very prominent on the upper side), and the wide dark border (barely showing through from above) are all characteristic.

Male, orange or clouded sulph
Male, orange or clouded sulphur; it's not always possible to tell which one as they can hybrydize, according to Brock & Kaufman (pp. 60-61). If you saw the upperside of the wings and it was distinctly orange, then you may more confidently call this an orange sulphur.
