I searched the more accessible showy and narrowleaf milkweed in my yard and found about 20 eggs. I saw none on my two swamp milkweed or three tropical milkweed plants, nor on my A. asperula.

This is the fourth or fifth egg-laying in my yard this summer since late June. I have seen no larvae succeeding since the third instars I saw from the first clutch (one of which I had protected outside for about a week).

I collected 13 eggs to protect for a while until they make it to 2nd or 3rd instars. They are in containers outside and so have natural temperatures and day length, but not direct sunlight. Presumably adults will be migrators.

So, some eggs laid today will be reared protected for a week or at the most two before being returned to the milkweed patches, while the other eggs laid - those I left where I found them and the others that are certainly out there where I did not search- will be left to natural circumstances. There is a good diversity of insects and birds, and snails, in my yard so I am not surprised that the eggs generally do not yield any noticeable larvae, chrysalises or adults.
