Post Hibernation Strategies

The key to successfully implementing post hibernation strategies is to keep butterfly immatures alive from predation, dessication, and mold during the winter as was discussed in our Overwintering Techniques section.

Like other rearing philosophies, post hibernation strategies naturally align themselves with three of the four stages of the life cycle of a butterfly--egg, caterpillar, and chrysalis.  I am also including a separate section on admirals and viceorys--since post-hibernation strategies for that group is somewhat niche.

Since the point of post hibernation strategies is get eggs, caterpillars, and pupae to break diapause or hibernation, some of the strategies and techniques to accomplish this include the following:

  1. Long day photoperiod (or daylength)
  2. Humidity (simulating a wet spring)
  3. Fresh hostplant for caterpillars that will resume feeding
  4. Isolation from sibling caterpillars to avoid re-diapause (especially applicable to Melitaeinae)
