Superworms in my humble opinion are a better option than mealworms, have you tried those, my Blanche rarely takes crickets, she just seems uninterested. Now pheonix worms have ended any food strike she had ever been on. Have you tried dubias? I don't have luck with them but I see a lot of folks do. I can't get my female to eat any fruits or veges so kudos on that. Hornworms are also really good but your cham looks the same size as mine and everytime I've gotten hornworms most are too big when they arrive. Good luck, light and love to you and yours.
