This morning we noticed that there were ten or twelve colorful little caterpillars on our Desert Milkweed, Aesclepias subulata.
Desert Milkweed is one of the plants we added to our courtyard landscaping, in hopes of attracting more butterflies.
Looks like they found it :-).
Pictures in our nature guide books identify these as the caterpillars of Monarch Butterfly.
These little guys are (presently) less than 1.5 inches long.
We will be keeping an eye on our new guests.
Hopefully we'll get some more cool pics as they feed, grow larger, create their chrysalis and metamorphose into adult butterflies.
