Honey bees build honeycombs from beeswax that they produce.After extracting honey from the combs, beekeepers store the combs until they are needed again as the bees build up their honey reserves.Wax moths lay their eggs in honeycombs.The larvae eat the wax as they go through cycles of molting and growth until they metamorphose into adult moths.Suppose a beekeeper decides to store his honeycombs in a cold room.Months later when he goes to get the spare combs out of the cold room, he finds them full of large holes and gigantic moth larvae, but no adult moths.Hypothesize about what aspect of the moth endocrine system was altered by the low temperature.
