The key to successful overwintering is to keep the larva or pupa in a COOL climate.

1. NOT AT FEEZING TEMPERATURES
2. NOT TOO DRY (especially important for hibernating larvae)
3. A NON-DEFROSTING refigerator or bar fridge is best for this purpose

Large pupa (Swallowtail size)

1. Diapaused swallowtail pupa are photo sensitive to lengthening days and will emerge in February, March or Apri if they are not kept cool
2. Containers are not necessary
3. Place in refrigerator in before December 21st
4. Bring out again in mid-April

Small pupa or larvae

1. Salsa jars can be used used to overwinter small pupa or larve
2. can hold many larvae (helpful for moisture retention)
3. Place larvae on "thoroughly dried" food plants or on similar plants
4. Glue small pupa to tooth-picks with non-toxic children's glue and place in the jar on a kleenex tissue
5. Remove lid ONCE EVERY TEN DAYS
6. *Successful with Tawny Emporer larvae, Silvery Checkerspot larvae
7. Bring out larvae when their foodplant is available
8. OPTIONAL warm larve few a few kours once or twice during the winter
9. DO NOT USED PLASTIC FILM CONTAINERS!
