These are relatively new on the market, well 90's actually so not really new - just not as popular yet. The company that brings these to the States and breeds them here is pretty secretive about breeding info. All i've found so far is a couple of YouTube videos and threads in reptile forums about people who have been experimenting with them. Apparently they're another tropical species, like superworms, so don't refrigerate them. On the plus side, the supposedly pupate easily with temps in the mid to upper 80's and eat the same grains/veggies as mealworms. They have a slightly shorter lifespan, but supposedly lay more eggs than regulars. They also seem to be much more active than regular mealworms. I don't know about cannabilism or how hard they are to raise, one guy on a gecko forum said he treated them exactly like mealworms, but kept them a little warmer. The beetles died and a month later he had hundreds of tiny minis. I use mealworms primarily to feed my Oscars, but some do go to the birds. These might be a viable alternative to mealies for younger birds/chicks. Here's a picture of them that I found online.
