On Saturday, my 4H students are going to learn how to graft. They've practiced on real combs but they were empty.

The temps are forecasted to be in the mid 70's.

How long can I have the young larva out of the warmth of the hive to complete the process?

Thanks-Ed

Joe Latshaw suggests a 3-hour transport limit for day old larva

Cold is not the issue, In Breeding Super Bees, Taber says

Eggs and newly-hatched larvae which have been separated from the bees will do best at 90-96% humidity and 33F. I have kept them on ice for more then 48 hours with no Ill effects

overheating, sunburn, and drying out are the main issues you need to address
