Ova
4 days
The female oviposited on host plant, Thymophylla pentachaeta/Dyssodia pentachaeta - Fetid Marigold/ Five-needle Prickly-leaf, and on the screen of the container which was set under the dappled sunlight of an Aspen.

Larva
19-22 days

Pupa
7 days - One pupa was formed on a flower stem and one on a calyx.  I put  recycled brown paper towel strips on some flowers.  Some of the larvae used  the paper as the surface to form pupae. The pupae were kept in 24x7 light.  I did not mist these daily because Jack Harry told me that members of the  sub-family Coliadinae preferred a somewhat dry environment in the lab.



Host Plants
Fetid Marigold/Five-needle Prickly-leaf - Thymophylla/Dyssodia pentachaeta

Other host plants listed in Butterflies of America by  James A. Scott are Dyssodia papposa, Bidens pilosa, Helenium autumnale, bigelovii, Cosmas, Palafoxia linearis, Tagetes, Thelesperma trifidum, megapotamicum.
