Silkworms equal more crickets as the silkworms get larger. Small silkworms are pretty much the same as a same sized cricket by length. (ie a one inch silkworm is pretty much the same as a one inch cricket).
Because silkworms have more protein and calcium than crickets, they are a great source of food. They are a little higher in fat but for growing babies, this is a plus. Silkworms have less waste bulk as well, lacking the hard chitin of crickets. When feeding silkworms, bearded dragon poo does become softer and contains much more liquid. This is normal, a refletion of the softer bodies and higher water content.
Silkworms have benefits in the fact they never make noice (except the sound of th em eating chow...which you can only hear if you are standing right beside them while they eat. But th en again when I have silks I usually have a few hundred... Also, they don't stink, providing they are cleaned regularly and kept as bacteria free as possible (silkworms are very vulnerable to bacteria, mold and high humidity). The general smell of silkworms is the same as the silkworm chow, a kind of fresh cut grass smell. They don't escape... in fact they don't move much at all, unless it's from one slab of chow to another.
Adult male crickets will chirp at any time of the day, though bright light seems to quiet them but not always. The males are easy to distinquish from females even at a young age. By the time the crickets are about half an inch long, you can tell the males from the females easily, so feed them off first. Females will have a third black 'spine' coming from the end of their butts. Males will just have two tan or clear 'spines' forming a sort of 'V' on either side of the poop opening. The third one females have will be between these two and just above the 'poop opening'. This is used to deposit eggs in soil and can grow quite long in adult females...even longer than their total body length (about an inch or so).
It's always good to feed a variety of insects to dragons, regardless if one individual insect is a great stable. Bearded dragons in the wild eat many insect species so offereing crickets once in awhile as a 'treat' is a good ideal. Superworms, waxworms, butterworms, several species of roaches, locusts, and some other insects, can be offered as a change from just crickets, or just silkworms. Waxworms should only be treats, same as mealworms. However a feeding of superworms or the others, once or twice a week, is perfectly fine.
For adult bearded dragons, one 2-3" silkworm is easily the same as 6 adult crickets. My adult bearded dragon would eat only 2-4 large silkworms, and more smaller silkworms. I offered silkworms for the first time when my dragon was about 6-7 months old and I started with one inch worms..I fed up to a dozen of th ese to her at that time (she was around 12-14" at this time. Her adult size was about 19"
. She did very well on these, filled out alot and gained size/weight much faster t han she did on crickets, not to mention her poop was less hard looking and she went more regularly. WIth crickets and greens, she often didn't go more than twice a week, with silkworms and greens, she went every day.
