And More Butterflies

White M Hairstreak/Parrhasius m-album on Groundsel Tree/Saltbush/Baccharis halimifolia. The inner wings on these flash an incredible dark blue in flight, hinted at here because of the chunk taken out of the forewing.

Black Swallowtail/Papilio polyxenes on Ironweed/Vernonia.

There seems to be some taxonomic confusion among the Colias sulphurs. I think this is Orange Sulphur/C. eurytheme. Also on Ironweed.
