Today I did a short survey of milkweed on selected patches that I thought would likely have larvae at various stages. I did the survey from about 9:15-10:30am. It was 64 degrees F, cloudy, lightly breezy, with 95% humidity.

These are the results:

50 milkweed checked
20 eggs found
21 larvae found

Of the larvae:

1st instar: 5
2nd instar: 3
3rd instar: 6
4th instar: 4
5th instar: 3

This is a photo of one of the 3rd instars as he nibbles on the tender buds of a milkweed (Asclepias viridis) this morning.
