In the summer of 1999, I noticed two butterfly larvae on the California Pipevine (Aristolochia californica) in my backyard. They each were black with yellow spots. I suspected that they could be larvae of the Pipevine Swallowtail, but they were gone before I could confirm my identification. Then on May 25, 2000, my wife found this butterfly on the Pipevine. It appears to have just hatched out. After several hours it flew away.

Several days later we watched as a Pipevine Butterfly (the same one?) layed seven eggs in two spots on our Pipevine.

Sometimes also called Claret Cup Cactus, grows in the rocks in the canyons along Wild Horse Canyon Road. My impression is that the species is more common on the Precambrian schist and gneiss, but I have no data to support that conclusion. Occasionally the species can be found on alluvial soils.
