PowerHobo: 1. Those are the containers I keep them in. The shallow substrate helps them find food quickly (helpful for several reasons), also they don't need/eat much of the substrate anyway. The containers with almost no substrate had mites recently (most of the ones up front), so I have been changing the substrate when I feed them to bring the mite numbers back down. 2. Most of my ventilation holes are in the lids, but a few are on the sides. I feed them every other day so they get a lot of air flow that way. 3-4: PM me
Titanus: Thanks! These are G.g. and this is my second batch of larvae - their parents all pupated and eclosed with no problems. I have actually had more trouble with hatchlings and early L1, pupation is pretty easy now.
