In the center of the field where I looked at some of the milkweed plants, there were many oleander aphids on the milkweed leaves |

| native swamp milkweed | I have several milkweed plants along my front yard and I check them everyday and today was the day I finally noticed some caterpillars!! I found 3 at what i assume is the 5th instar stage, they are all quite large at this point and have the antennas fully developed. They are happily eating the leaves. |

| 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 |

| Asclepias incarnata | See also observation number #24136 for 8/23/2024. same narrative copied below.
Planted a single Asclepias incarnata plant on 6/9/2024 in a new flower garden in the backyard of a residence. The plant was purchased at a garden center.
Noticed ten caterpillars on the plant on 8/23/2024. Within 48 hours, observed formation of six chrysalides. Two of the remaining caterpillars died and two disappeared (either died or we can’t find the chrysalides). One of the chrysalides disappeared the next day (assumed eaten) and five chrysalides remain intact as of 8/29/2024. Performing daily observation. |

| Common milkweed | I looked at 22 common milkweed plants. Out of the plants I looked at, there were four eggs and one instar. Two of the eggs were on a shorter milkweed plant (about 6" tall) that was in the middle of the walking trail. I also saw one empty monarch egg shell on a milkweed leaf. There were two monarch butterflies that flew by, but I couldn't tell if they were male or female. One of the monarchs had very muted coloring.

| Common Milkweed | Checked two common milkweed plants for signs of monarch eggs or larvae; found two small monarch larva on separate leaves - caterpillars with yellow, black, white stripes, two tentacles in front and smaller ones in back! Same instar stage - believed to be 3rd instars (the front tentacles would reach the tip of the head in length if we folded them over but not extend farther, back tentacles shorter than that). |
