zero742,
You bring up an interesting question concerning the nutritional value of superworms vs. the other typical feeders...I have browsed over some of the charts like the one Brad mentioned...I always wonder about the scientific accuracy of some of those tables/charts and what diets these feeders were on from these studies. At any rate, it seems like the general consensus is that superworms may be too fatty to be used as a staple food source (again not sure how much of this is based on medical evidence). As an owner I find superworms one of the easiest feeders to take care of as they do not require much upkeep (e.g. compare with silkworms), don't make much noise, and can last a long time. I still have thousands still alive from some I ordered 5 months ago. Variety is always important as my chams are pretty bored of them lol...
I just found one of those beatles crawling around one of my plants the other day...much scarier to me than the larvae/worms...last one I found my chams would not go for, however
