Return to Life Cycle Studies of Lower Rio Grande Valley Butterflies

On 7/20/2007, I found a Crimson Patch - Chlosyne janais caterpillar on Flame Acanthus - Anisacanthus quadrifidus wrightii.  I collected the caterpillar for rearing.  A week later it made a chrysalis, and another week later the buttefly emerged.

Flame Acanthus - Anisacanthus quadrifidus wrightii, is native to the Texas Hill Country, and NOT native to the Lower Rio Grande Valley.   It is a host plant for the Crimson Patch, but Smallflower Wrightwort - Carlowrightia parvifolia is the Valley's native host plant for the Crimson Patch - Chlosyne janais.
