This is the same location I've been observing most of the summer. The patch of common milkweed had 3 larvae that I could see. Some of the plants are too far into the weeds and brush for me to get to. All caterpillars seems to be 4th or 5th instar. At various times in the last few week I observed up to 14 larvae in this patch. In fact, I moved 9 to this area (put them on different plants) from a single swamp milkweed plant that had 17 or more caterpillars on it. Near this patch is a chrysalis that I've been observing for 4 days. The swamp milkweed plant had 3 larvae on it, all seemed to be 4th or 5th instar. Two larvae were in the long grass at the base of the plant. One appeared to be 5th instar, the other 3rd or 4th. The larger of the 2 was crawling around over the grass...I wondered if it was looking for a place to anchor itself for pupa stage. The spot where this plant is isn't ideal. There aren't other milkweed plants around and it's in tall but flimsy grass, between a fabric construction fence and a walking path.
