How long ago did you get your mealworms Eddie?
About a week. They were med-large when I got them....a pretty good mixture in sizes. They were in around 75 degrees when I first got them. Then I threw an electric blanket over the entire 3 drawer system and now they been in 80 degrees for 90% of the day/night. 2 days after the blanket, I started seeing some excitement and some pupa.
