Longtail Skipper

Ok. While you think about this one, you can play with the white one! :-D

I am not the master but I have some doubts about Proteus and a definitive ID...

Ok, Bayucca, you are the master here. Already fixed.

Definitely Urbanus sp. however even with my books I would probably not be able to get to a definite species since they are all very similar. My candidates:
Urbanus belli: /butterfliesofamerica.com/urbanus_belli.htm
Urbanus esta: http://butterfliesofamerica.com/urbanus_...
Urbanus esma: http://butterfliesofamerica.com/urbanus_...
Urbanus pronus: http://butterfliesofamerica.com/urbanus_...
Urbanus pronta: http://butterfliesofamerica.com/urbanus_...
Personally I don't think it is Proteus: This one should have some additional little spots on the forewing and should have some white stripe on the hindwing (see #2 next to the dark tail):

Tx again, Bayucca.
