Hello monarch experts!
A few weeks ago I found a fourth instar caterpillar on the milkweed in my garden. I took it inside to save it from the frost that was predicted in the following days. Due to the cool temps it was slower to develop than the cats I had earlier in the summer, but finally it looks ready to eclose at any moment. Alas, though, I am afraid he's missed the chance to fly south, as the weather is not looking great. I'm in Madison, Wisconsin, and the extended forecast includes no days above 60°F: the current prediction is for several days with part sun, highs in the mid 50s and lows in the mid 30s; and one day of showers with similar temps. There may be a slight warm-up around Nov. 5th, which is currently predicted to be sunny and 54° but with a low of only 40°. Still, I'm not sure that any of those days will be warm enough for him to fly. Also, food is looking scarce. I can find a few remaining patches of viable flowers, but most have gone to seed and dried. What should I do with the butterfly once he eloses?
Thanks so much for you advice!
