I'm having this same problem as of now! Pascal is hooked on crickets! I've ordered him silkies (he ate 3 out of 50 ordered), phoenix worms (ate like 5), small supers (liked them for two weeks and then said "nope!"), butter worms (just stared at them), and just yesterday I offered him dubias. I kind of had to trick him into eating them by giving him a cric, then snuck in a dubia, then cric, ect. I pray he will just get over this and start eating variety! I offered all the bugs (besides dubias) for weeks!!! Ahhh! Frustrating. He will gladly take wax worms (which are basically junk food so he only gets those twice a week). Sorry to poach your post but I'm eager for advice as well!
