Temperatures that are too cold will delay monarch development. One monarch caterpillar can eat an entire milkweed plant in the 10-14 days before it turns into a chrysalis. The monarch pictured here can only crawl. They’ll eventually eat when hungry enough or after they are finally released. By the time the temperature cooled enough to trigger the migration, it’s been too cold in the Midwest and many monarchs died on their trip south. You can damage the butterfly’s wings and do more harm than good. When you release your monarchs, they will want nectar-producing flowers. In recent years, the monarch’s fall south migration from Canada has been delayed by as much as six weeks. However, we are expecting a snow storm with freezing temperatures, around 28 degrees. The monarch's migration is driven by seasonal changes. The monarch butterfly (Danaus plexippus) is among the most recognized, studied, and loved of all of North America’s insects. If temperatures are too cold, they can freeze to death. Monarch Butterflies greatly rely on the cue of colder weather to not only prompt their migration to Mexico, but also their return to Canada and the U.S. too cold for monarch? They can't even crawl below 41°F. Monarchs are being studied all the time. My monarchs are currently in the chrysalis stage for over a week now. If a butterfly is native in your area, then the chrysalis will generally have no problem surviving a normal winter. If you come across a butterfly basking in the sun on a cold morning, resist the urge to pick it up or move it to a “warmer” location. Serve monarchs all food options at room temperature, as butterflies are sensitive to cold. Daylength and temperature changes influence the movement of the Monarch. Ice crystals that form on the butterfly can kill it. Don’t forget about adult butterflies, too. Butterflies will remain sluggish and incapable of flight until their body temperatures reach about 80 degrees. Add fresh milkweed every day to ensure monarch larvae have quality food.

Because the chrysalis needs short days and cold temperatures to keep it in diapause, probably one of the best places you can keep it is outside in a protected area. Monarchs can't fly unless they can warm their muscles to 55°F. Awareness of the monarch butterfly’s life cycle and habitat requirements is essential for their survival and an important step in the conservation of this animal. When monarch butterflies overwinter in central Mexico and along the California coast, they spend much of the time dormant to help with their winter survival before reproduction. Keep rearing containers out of direct sunlight and make sure that there is not too much moisture (paper towel should be moist, but not dripping wet). If diapause ends too early, monarchs may lose some of the protective time the dormancy period provides. Don’t raise monarchs completely inside. ... condition in the wild—cold temperature—sped up the timer." No problem surviving a normal winter on a hunger strike…we ’ ve butterflies!
