- At the time of this observation, the location was not yet listed as a survey site. I was just thinking about doing it next year. But when I observed two advanced instar monarch caterpillars on one tired looking milkweed plant, I decided to do a full sight survey for practice. I came back the next day and collected one of the caterpillars to try my hand at raising it. That one was released as an adult today 10/5/2025 This evening I entered the location as a survey site, and plan to survey this location again next year.
