Last night we had a hard frost. A male monarch hatched in my horse lean to earlier this week and has been hiding under a snow shovel leaning against the wall, covered by shade. I brought him in last night, carried on a sprig of goldenrod. I put some gatorade on a folded paper towel, a slice each of honeydew and kiwi, and a couple of milkweed leaves in a plastic barrel (like pretzels come in) and put him in. I kept him in the laundry room which is a colder room in the house (60's). It was 37 this morning so when it was direct sun and almost 50 I put him back outside by his shovel, half in sun and half in shade. He spread his wings and warmed. About 11:30 he flew off over my head. He has been flitting from aster bunch to aster bunch since warming his wings in the sun, but is staying close. Tonight is "scattered frost", followed by warmer (50's) and possible wet weather on Wednesday. Then a warming trend is predicted with days in the 70's for about 4 days after that. I never saw him eat, but he sure seems happy outside in the sun today. Should I try to catch him again as the sun is setting (I figure he'll be less flighty then) and bring him in until the cold and rain passes or will he have instinct to get out of the patchy frost before his journey? It seems so late, but I want to do the right thing by him since he sought shelter here!
