Raising mealworms

[jwlee]

I just started a mealworm farm 2 weeks ago. Does anybody know how big they get before they turn into a pupa? Mine range from 0.5” to 1.5”.

In length?

In length?

I meant, if you want to know how long they are once they are ready to turn into pupae its not really measurable, I find that they don’t change much in length once they are full grown...however I find that when they all start becoming pupae, they are quite thick though, and they start to shed a ton!!!

agreed; those about to turn are really chunky. Look at their girth as well as their length.
On length, I don't think I've had one longer than 1.5", so that must be close to the max if they're regular mealworms.

Thanks for the info! I just found my first pupa! I’m super excited!
