Visiting Var in May 2005 and in early spring every year since, crameri has been relatively common. The female has a heavier forewing discoidal spot. The second brood unh is a yellower green, as shown in 0618 but the date is one week earlier (!) showing the impact of altitude on the flight season (emergence is later at altitude) as 0828 was seen at 1000m.

Euchloe is a confusing group, with a relatively recent subdivision into Eastern (ausonia) and Western (crameri) Dappled Whites, and there is also the Mountain Dappled White (E. simplonia) and the smaller Portuguese Dappled White (E. tagis) which is found in the south-eastern corner of France. Crameri also bears a superficial resemblance to the female Orange Tip (Anthocharis cardamines) although there are significant differences in the shape of the discoidal spot and the white areas on the black apical mark.

the ground colour is a much darker green, indicating a first brood, the flight season being retarded even at moderate altitudes of 1000m. The body length strongly suggests a male.

a male, based on the lightness of the cell spot and a stronger white spot in the upf apical area.

the wings are slightly open, and the apical white mark possibly suggest a male. The body length also slightly suggests a male. Oddly, even on 15 May, the yellow ground colour suggests this is a second brood, quite possible as crameri is a very early emerger in Var.

this is very yellow-green and may be a second brood, even in mid-May. I'm guessing it's a male.

I'm guessing that this is a first brood female from some subtleties of the unh patterning based on the illustrations in T&L, plus the slightly large unf cell spot.

no doubt about this one, as it is ovipositing on the larval hostplant Buckler Mustard (Biscutella laevigata), it is therefore female.
