Well, I decided to give her a chance. I was going to my parents yesterday which is 1 1/2 hours south of me in the SE corner of Wisconsin on Lake Michigan and brought her with. It was cloudy, cold and was set to freeze last night with a low of 28 through the night. So, we left her in the mesh enclosure all day yesterday and put a bunch of flowers in her tank and kept her indoors last night as to avoid the freeze. She quickly took advantage of the butterfly bush in her enclosure. So, this morning around 11:00 a.m. my parents put her outside on the butterfly bush and she quickly flew up and did three circles and landed up high in a tree. It was only in the 40's but sunny. Rain and cold expected tomorrow (not freezing though) and then 50's during the week. I'm glad I gave her the chance to be free. I wonder if the late year monarchs are somehow stronger than the summer monarchs? My dad said when she flew away her wings seemed stronger and she soared immediately rather than flutter for awhile like most do in the summer when they first fly.
Please watch for her coming through Texas in about a month.
I'm hopeful she's gonna make it.
Thanks for all the info.
