Here in my part of California they prefer anis. I'm waiting to spot the first caterpillars on the anis clumps I deliberately cultivated outside my kitchen windows.

Anise? The reference says milkweed, period, and that is what I had thought. I did a quick search and suspect it is another butterfly, maybe this, but don't quote me.

Wright is probably thinking of the Anise Swallowtail, Papilio zelicaon, which uses anise, and more often, sweet fennel, as a food plant for its caterpillars.

I stand corrected, Stanton. I've seen Swallowtails around those anise stands in past years.

Aside from them living on different plants, the caterpillars of the Anise Swallowtail and Monarch are extremely similar (i.e., black stripes on a pale green/white).

The Monarch caterpillar I photographed a couple of years ago.
