Larvae on (Bahia absinthifolia) Desert Bahia - Asteraceae (Sunflower Family)
Dog Canyon, Otero County, New Mexico
Desert Bahia is a very common plant  on the alluvial fan outside of Dog Canyon.  When I first saw the yellow larvae on the left, I was thinking sawfly, until I noticed all of the appendages of a caterpillar.  The small Nymphalid larvae on the right  is probably Chlosyne lacinia, which is said to be highly variable. (Brock 2005).  Any ID help with either would be greatly appreciated.
