Have you tried adding some worms as lures to the salad? Or you can w/ hold the insects for a few days get him hungry and keep offering the salads- they are stubborn and if he's healthy enough he will not starve himself and will eat the salads- usually they like the taste of calcium and will eat the greens-- there is always a liquid calcium you can give in like a shot of water thru syringe-- vitamins 2x per week dust the bugs w/ it--- are you getting your insects from thewormlady in Canada?
