Sudden onset anorexia?

Jerry stopped eating 2 days ago. I normally feed him 6 days a week, 10-15 crickets. He gets multivitamin dust 1x/week and calcium dust 3x/week. He is cup fed and has a cup of fresh water available at all times. He also has a dripper 12hrs/day + misting 3x/day, urates are white. Fecal matter does not look abnormal, frequency is normal. I do fecal floats monthly to check for parasites. UVB 5.0 12hrs/day, bulb replaced 2 months ago. Temps are 85-90 basking, ~75 ambient. He has a dracaena and a pothos for cover.

About to go out and grab some meal worms to try tomorrow morning. Any suggestions?
