| swamp milkweed | These are on our personal property so have been monitoring them for past month or so. Numbers change daily as sometimes its really hard to find the really little ones, and they are growing, but we generally find several every day. Had 2 earlier caterpillars that went through total metamorphosis and became monarchs. .I was able to get a clear photo of one fairly close to when it emerged (within an hour) which I submitted to your site. At one point we had 6 caterpillars that I would classify as a 5, in one clump. They were gone next day so not sure if they moved, or were eaten. |

| Swamp? Photos available | This area is a transmission line right away that has been planted with native prairie grasses. There are 3 large patches of milkweed (I guess at over 1000 square feet) with several hundred plants each, as well as individual plants throughout larger area. All patches have significant evidence of very hungry caterpillars. I didn’t count plants, nor did I look at each plant to count. I found these Monarchs easily near the top of plants (or flying). Photos available. |

| Common milkweed | Saw monarch butterfly getting necter from a flowering plant and then flew away. Time 3:12 p.m. At 5:23 p.m. Same butterfly came back to where a larva was. When it noticed me it flew around to other things near the milk weed that had a larvae. Then when I walked away it went down into plants I pushed together due to the hurricane. The larvae had eaten 5 leaves ASAP then moved down the plant exploring to the point that I did not see it until about 6:15 p.m. The larvae grow so Long and plump. It is beautiful with all its boot like feet. Have pictures on my phone of them. |

| Common and Marsh/Swamp Milkweed | Rainy day, one male butterfly observed late in the day. The wind pushed taller common milkweed plants over and in the process of anchoring them again and checking other milkweed, I observed two 4th instars on marsh milkweed and one 4th instar on common milkweed. These have not been observed previously. |

| common milkweed, swamp milkweed | The recorded observations are from my neighborhood in Arden Hills. I also checked about 30 common milkweed plants in a field that was about to be hayed in Austin MN on 7/16/2020. I collected ~10 eggs and 5-10 caterpillars at that point and brought them to my home in Arden Hills. One of the caterpillars was infected with Tachinid fly eggs and died. All others lived. I raised them outside. There is more milkweed starting to grown in my neighborhood and I have been trying to spread more seeds. Unfortunately I have seen a lot of milkweed plants mowed. |

| Common milkweed and butterfly weed. | We've seen lots of egg laying happening by two monarchs this summer. Lots of eggs and caterpillars on our plants again this year, but not many are making it to adulthood. Seems to be an increase in predators this year, specifically wasps and spiders that we assume have eaten the caterpillars (although this hasn't been witnessed). Our milkweed is also in pretty bad shade right now. Due to the number of eggs, I didn't cut any back, so there is not much new growth for them to feed on. Next year, considering starting some plants by seed in pots at various times throughout the summer so there is new growth, adding a puddling station and transferring some milkweed to a sunny hillside location in our yard. |
