Its a good idea to feed a variety of healthy gut loaded insect to your chameleons. Crickets are a main staple along with other insects. If your not digging the crickets as a main feeder, you can try your hand at with dubia roaches and or other roaches. I personally prefer the roaches since they are self sustaining and breed like crazy. However, I still feed my chameleons crickets, silkworms, hornworms, superworms, fruits flies since they are available to me most of the time.
