How cold can it be for Monarch Caterpillars to survive? Monarch Butterflies can crawl at temperatures of 41 degrees, and need a temperature of 55 degrees to be able to fly. In terms of mortality, Monarch Butterflies can survive temperatures of around 17 degrees, but not for very long, and around 50% of Monarch Butterflies will die at this temperature.
But what about Monarch Caterpillars, how low can the temperature be before they begin to die? There have been caterpillars in many stages of development on the milkweed this week and maybe they will be able to survive mid 30's nights...
Can anyone help answer the question above? Some of us are really curious.
