Descripción

Two males were watched here, but I only got photos of one. They were defending territories from one-another and several other butterflies (and my camera); including Papilio multicaudata and Vanessa cardui.

This one was using a Callirhoe involucrata plant as a perch, the other was using a perch across the path about 5 ft. up on a Mahonia trifoliata bush.

Descripción

Trimerotropis saxatilis as found along the base of the Front Range in Colorado. The first shot is a comparison of females of T. saxatilis with T. pallidipennis, but caught at the same time in the same location. T. saxatilis excape flights are usually relatively short, and they often curve back on themselves; they nearly always land back on the rocks. T. pallidipennis (females especially) will generally take longer more direct flights and will land on any open substrate, caring not if it is on the rocks or on some patch of dirt or pavement.

The bodies of these two are approximately the same size, but the pronotum is proportionately shorter on T. saxatilis and the wings shorter and proportionately shorter, with a dark band that often doesn't follow the outer margin as far and is often wider, and the disk of the wing usually richer in color.

The last two photos are a different individual than the previous ones.
