Calci-worms are also known as Phoenix worms or Reptiworms, and they are the soft bodied larvae of the Black Soldier Fly. I do use them as a staple feeder for my beardie. He is 7 months old, and I have been using them for about 3 months. They are not as fattening as wax worms, but they do have a slightly higher fat content than crickets do.
Pros:
They are very high in calcium (good for beardies!), so you don't have to dust them with calcium powder.
They are more convenient and easier to take care of than crickets.
You don't have to feed them. You just leave them in the cup they came in.
They last for 2-3 weeks or so at room temperature, and will last even longer at about 50F.
They are pretty small, so younger dragons can handle them.
You can put them in a dish in your beardie's tank, and they can't get out (unless they are wet). So you can leave them for your beardie to eat throughout the day.
They move around a lot, so they attract the beardie's attention.
In my opinion, they are not nearly as scary/disgusting as crickets :lol:
Massive help! Thankyou
Cons:
They are more expensive than crickets.
Even the large size ones are pretty small, so if you are feeding a very hungry dragon, they will go through a lot (mine can eat over 100 in a feeding).
I feel like there should be more cons, but I can't think of any right now. Hope this helps!
