Orange Sulphur - Colias eurytheme - female

Orange Sulphur - Colias eurytheme - Female
John Heinz National Wildlife Refuge at Tinicum, Delaware County, Pennsylvania, USA
July 15, 2007
Size: Maybe around 2.5 cm?
I think that I narrowed it down to Colias, then they all started to look alike.
I kind of liked Clouded Sulphur (Colias philodice) maybe a bit more than the others.

one more thing
This is a female. You can see the pale spots within the dark border showing through from above. Agreed though, Colias eurytheme it is.

 
Thanks
Got it

That
was quick. I just commented a few minutes ago. Thanks.

I would suggest
that this is eurytheme. The bright spot visible through forewing just above edge of hindwing is indicative of Orange. Clouded doesn't have such a spot.

 
Thanks
Thanks for sorting these out. I don't know how to reconcile the "bright spot" vs. "dotting on the forewing", but I will go with the flow. :-)

 
To me
the "bright spot" is the orange showing through from the other side of the forewing and that should take precedence over any dotting in both male and female Oranges. To say this another way, the entire part of the forewing in Clouded is a uniform color except for the black portion, of course. I think that with your specimen it's pretty clear that it's the orange color showing through but some Orange have very little orange on the forewings. That could be a problem with early season or very worn specimens.

this one I'm inclined to say
this one I'm inclined to say male clouded--colias philodice. For a female, one would see a more open spot rather than that black smudge on the forewing...and also, with the orange male sulphur (eurytheme) you'd see more dotting on the forewing, in line with the dots on the hindwing.

just my impression whilst looking at my copy of Brock & Kaufman.
