Today I did a milkweed survey for monarch eggs and larvae. I looked at 251 native milkweed plants (Asclepias viridis) and found a total of 213 eggs and 33 larvae. I did the survey from 10:30am – 4:30pm, covering about four acres.
It was a cool, overcast day with temps in the mid-60’s. I saw monarchs at times, including three egg-laying females around noon, but it was a bit chilly for their usual activity. I observed a good many newly emerged milkweed plants, so there are good options for the monarchs in the coming days.
These are the monarch egg count results:
107 milkweed w/0 eggs
102 milkweed w/1 egg
27 milkweed w/2 eggs
9 milkweed w/3 eggs
2 milkweed w/4 eggs
3 milkweed w/5 eggs
0 milkweed w/6 eggs
1 milkweed w/7 eggs
These are the monarch larvae count results:
1st instars: 27
2nd instars: 6
Notes: Some of the milkweed with 0 or some eggs also had one or more larvae.
This is a photo of one of the milkweed plants with two monarch eggs near the bud crown.
