Mine took 7 days my colony is kept inside w/ a temp between 76-78
Wow I had no idea it was that quick! I was looking up the life cycle of the mealworm and found a diagram at enchanted learning. On that site it says the pupal stages lasts from 2-3 weeks up to 9 months! (9 mos being overwintering).
My colony is right at 2 months old. When I got them they were large meal worms and it took almost two weeks to start pupating, but I have my second gen mealworms (those hatched from my adult's eggs) that are getting close to pupating themselves (probably the first ones in the next couple of weeks) so from my colony observations, having constant indoor temps, and all the food they can eat it looks like 3ish months from large mealies to large mealies.
