View 8/7/2017 Winchester VA Other  Clearing out my side yard, decided all the milkweed plants that had sprouted and not provided but one Monarch had to go for the sake of the mowing this year. I cut off all the seed pods and was going to donate them locally. But the woman was charging two dollars for each packet of seeds. I want to DONATE them. Would you like to have them? The stalks are still here, I can look for stuff on the leaves and stalks. Thank you so much. Barbara J. Fogle

View 8/6/2017 Windham NH Monarchs common milkweedFound one large pupa. Will protect it with netting and monitor. Will probably put it in a safe cage for the chrysallis stage so that we can release it as a butterfly. This is the first in this spot in probably at least 4 years. Prior to that, we would have several each year. This is a butterfly garden where I planted milkweeds on purpose.

View 8/6/2017 Sabinsville PA Monarchs commonThroughout the blitz I covered a field of a few hundred thousand common milkweed plants by staying on a mowed circular path around the field, and just checking the milkweed that grows along the path.I did scan the entire field for monarchs. I checked for eggs, etc. on three of the days, the first, a middle day, and the last day as time was not available to allow me to do that every day.

View 8/5/2017 Robinson IL Monarchs swamp milkweed, common milkweedMarathon Petroleum Lincoln Trail College wildlife habitat. Observed numerous swamp milkweed plants and common milkweed plants. No eggs / cats observed on the common milkweed. 6 cats observed on the swamp milkweed. Great photos were obtained. The common milkweed is in the seed pod stage and is no longer blooming. Swamp milkweed is just now starting to bloom. I suspect this location will be a very good monarch habitat for the next couple of weeks. Also observed 3 large northern water snakes, tussock milkweed caterpillars, 2 wild turkeys, a red admiral butterfly, a viceroy, leafhoppers, praying mantis, black eyed susan, 100s of young cottonwood trees, blackberry briars, persimmon trees Canada Geese, black swallowtails, spicebush swallowtails, Easter Tiger Swallowtails, and bee balm.

View 8/5/2017 Springfield IL Monarchs CommonAlthough I checked 25+ common milkweed plants, I only saw 2 eggs. It was getting dark and I was moving a little quicker than I would have liked, so I didn't get stuck out in the dark. This is in my back yard and there are MANY more milkweed plants to check. I plan to go back out tomorrow, but wanted to get my observations in, since this was the last day. Also, saw one 4th instar today eating on a common milkweed. I have 1 I brought and put in a butterfly habitat outside that is in 5th instar stage. It is hanging in the "J" and will make a chrysalis soon. Last Friday, when I was mowing the trail in the tall grass and milkweed, I saw at least 6 monarch butterflies flying around the area.

View 8/5/2017 Harpswell ME Monarchs Common MilkweedMy data consists of 4 separate areas of Common Milkweed plants in my field. It is easier to enter this all in as one because I had trouble using the area tool trying to do each one. About half of the milkweed is in poor condition because we have had hardly any rain for about a month and a half. I moved caterpillars found on poor plants to healthier ones to help them. It's too much for me to do regular monitoring but I wanted to contribute to the Monarch Monitoring Blitz. I see at least a couple adult Monarchs every day here for about a couple months now.
