I think silkworms are awesome. They are pretty easy to care for, they don't stink, they don't hop all over the place, and I don't think I have ever had one die. I breed my own right now, but besides www.mulberryfarms.com, there is also www.silkwormfarm.com. I think the latter of the two has better prices. I still feed my dragons crickets, just not as many, and trust me, they really like the silks! You dust them with calcium and multivitamin powder the same way you do the crickets. I think variety in a dragons diet is probably the best, this is why I still feed some crickets to them, and of course the occasional superworm, waxworm or butterworm. And of course their daily greens and veggies!
