Found this J-shaped monarch caterpillar this morning hanging out on a calendula plant in my garden. By late this afternoon, the transformation to chrysalis had taken place. Spotted the Eastern Tailed-Blue female and Northern Crescents while walking on our property after the rain ended and the sun peaked out briefly. Breezy and 67 degrees.

Sunny, breezy or intermittent wind, about 78F. Migrating Monarchs throughout the prairie.

Notes: Monarchs and Swallowtails were very fresh. 2 Black Swallowtails were paring deep in the brush. Very nice species diversity for this park. Orange sulphurs were very large and colorful. The Clouded were very gray and almost greenish. Duskywings and the Tortoiseshell were lifers.

Gardeners are not planting as many zinnia or tithonia blossoms for the migrating monarchs. There seems to be less diversity in the prairie plants, too. I was hoping to catch migration when it starts. 77 F, 10 mph N wind, 14:00 - 14:34

Great place for butterfly surveys: I nearly always see Monarchs here during their flight season. Unfortunately, I only had my cell phone with me today, and my photos were horrible. The butterflies were busy flitting away. Perfect conditions: high 70s, very light wind, plenty of nectar flowers. Monarchs were mainly flying SW, presumably migrating. I'm sure there were many more butterflies; I was walking my dog and interacting with other dogs and dog owners.

They were landing on the grass then moving down to the ground.

The Purplish Coppers were on both sides of Archer Road within 250 meters of the road (2 were in the roadside), all less than 1/2 mile wet of County Hwy W. The Variegated Fritillary was nectaring in the same patch as a Purplish Copper and was pestering the copper.

My brain was doing weird flips as I watched this butterfly this morning...What is it? What is not making sense? It's a Viceroy with almost no hindwing black cross band on the upper surface. I have never seen this before. A better Monarch mimic is born!

We walked about 1.3 miles in the grassland in plots north and south of Archer Road, and we each walked 0.5 different mile of roadside along Archer. The male Purplish Copper was 150 meters south of Archer Road, about 550 meters west of County Hwy W. The Question Mark was flying south like we have often seen Mourning Cloaks do in the autumn, and it was fighting a headwind.

13:26-14:03, 73 f, E wind, 7 mph, sunny. This area used to be loaded with migrating Monarchs but I have seen very few monarchs there this year. People are planting fewer tithonia and old fashioned zinnias than in the past. There were plenty of various bees and wasps.

Along these roads in the vicinity of Rettenmund Prairie SNA, there have been vast fields of Alfalfa with Thousand(s) of Clouded Sulphurs and a few Orange Sulphurs. They are a spectacular sight and it has been this way for at least two and a half weeks. This is the way the Universe should be!

Sunny, 78 degrees, gentle breezes. The Silver Spotted Skipper and Dun skipper were in my garden while the rest of the butterflies were spotted in the unmowed strip along my driveway. I was surprised to see the Dun Skipper this late: I haven't spotted any for a few weeks.
(The Dun Skipper is a new late date by over three weeks and only the third ever in reported in September. MR)

Both Sleepy Orange were males and spent all the time that I was able to watch them, patrolling for females. One along the road was so fast I couldn't keep up with it, even if I could run like when I was young. The second one in the tall grass just flew circles around me and stopped once for enough time for me to think I was going to be able to photograph it.
