Any suggestions on what, or how, I can spark the appetite of my juvenile (approximately 6-8 months) male Jackson chameleon named Leon? I offer him dusted crickets (small to medium sized), small silkworms, black fly larvae, and small super worms in a shallow dish every morning. He used to take them from the dish when I first introduced it back into his enclosure (18"x18"x36" screen). The crickets are usually found elsewhere in his cage, but eventually disappear after a couple days. He used to be a more aggressive eater (especially the crickets), but I haven't "observed" him eating anything lately. He doesn't seem to be ill and wanders his cage as if hunting for food. The black fly larvae are usually gone in a day, or two so I only add a few fresh ones each day. The silkworms and super worms seem to eventually disappear too, but I'm curious if I'm doing something wrong, should I offer something different, or what? He seems shyer than he was originally, so I try not to disturb him too much after feeding him. Thanks.
