Return to Life Cycle Studies of Lower Rio Grande Valley Butterflies

On 10/6/2007 I found a recently laid cluster of eggs beneath a Straggler Daisy or Prostrate Lawnflower - Calyptocarpus vialis leaf, and I collected the leaf to rear the eggs (suspecting them to be Bordered Patches - Chlosyne lacinia adjutrix).
