I have 2 that seem to be the same way. At first they went after the crickets then I guess when I fed the meal worms they got lazy lol. I feed wax worms sometimes, I was told that they fill them up fast and you don’t have to feed as much or often.I have a leopard gecko that seems hungry and is happily eating wax worms but not her locusts. She seems happy, healthy and active. Any suggestions? TIA
