Rearing cages, terrariums, and containers do not necessarily need this intense a light source to keep them from hibernating.

Light on Speyeria Species

When rearing Speyeria species, one technique to break unfed first instars out of diapause is to place them on the leaves of fresh violets or pansies. When the larvae move around to find a place to hide to diapause, keep moving them over and over while exposing them to high humidity and 24 hours of light a day. Usually, within 96 to 144 hours, they will start feeding.
