| | I did not notice milkweed but saw 4 what I believe to be different monarchs in the marsh behind HANC. 2 were together in the same part of marsh and were the tiniest monarchs I have ever seen. Another one was close by and was normal sized and a 4th I had seen earlier in another part of the marsh. I do not think they were the same monarchs. |

| Asclepias fascicularis | I observed 5 monarchs nectaring on a large lantana bush and narrowleaf milkweed blooms. There were several bushy stands of narrowleaf milkweed that were in various stages of going to seed and blooming- they did not appear to have died back during the winter! A few of the adults were males and one was rather tattered looking. I did not observe any mating behavior or egg depositing on the milkweed. |

| One 2nd instar that was observed on A. fascicularis was dead on the plant. But when I went back for my weekly monitoring later in the week it was not present so it is not in my data. Also on 10/6 not during a weekly monitoring session, I observed a clearly diseased chrysalis growing on a tomato cage. It was dark brown and mushy looking. I posted photo on iNaturalist. I did not really do a survey on these days, I just observed in between surveys | Did not want to record in the data columns above because both sightings were deceased |
