Today I looked at 459 milkweed plants over the course of the day. The first stretch of the count was from 10:30am to 2:30pm, the second stretch was from 5:00pm to 7:00pm. The temperature at the start was 70 degrees F, humidity 79%, winds SE 12mph, and it was mostly cloudy. At 7pm, at the end of the count, it was 74 degrees F, humidity 66%, winds E 9mph, and mostly cloudy. Of those 459 milkweed plants examined: 246 had no eggs or larvae seen. On the remaining 213 plants, I found a total of 233 eggs and 53 larvae. Some of the plants had multiple eggs and/or larvae. Some of the eggs were about to hatch. Of the larvae found: 31 were 1st instars, 12 were 2nd instars, 8 were 3rd instars, and 2 were 4th instars. I observed 3 dead 2nd instar larvae (2 with spiders right on them ): ~ not added to the larvae total. It was a long day, but the clouds helped make it doable. I am pretty sure I missed some eggs, some newborns, and some larger larvae off of their plants ~~ but it is a fair enough snapshot of the nursery today.
