Yeah, I really think it was a combination of things. His possible age, winter, laziness, or even just plain attitude. Mostly I am going with the winter though. I also noticed that he actually hunted down the supers and had to do the same with the 2nd hornworm. I am wondering if he has been too spoiled with having the feeding dish. Really looking forward to the next full clean out so I can get accurate interior measurements of both tanks. Once I have those I can move forward with getting them both on tile instead of the paper towels.
