It's hard to tell from the picture, but it looks like bite marks to me. Poor little Hornworm some other worm took it really hard on him and then he got discarded at the end. But sure, it is better to be safe than sorry.
Once Hornworms reach size of 1-1/2" it is recommended to keep no more than...
If you only give him crickets and mealworms he might be going on hunger strike. Chameleons get bored with food pretty easily. Ideally you should ofer him 5 different feeders. Silkworms, Hornworms, Butterworms are really nutritious, bright in color, so it will get his attention. These worms are...
When I saw in Petco 2 month old veild chameleon living in the 2" water swamp at the bottom of the cage with all dead worms in the bowl, I thought my heart will break. I felt so bad for little guy. I wanted to take him home right there and then. I got so mad and insisted to speak to the manager...

Try to creat a natural nature environmet with live plants, dripping water, so your cham would feel like he is outside even thoug he is indoors. Make sure you have screen mesh terrarium instead of glass, so no reflection, easy ventilation and air flow. Sun is very important, it helps absorb...
Try to give your chameleon some food first and then slowly put your hand next to him. Chameleons don't like any sudden movements it may scare them. See if it changes anything.
