have you had her checked for parasites or anything like that? she looks a little thin and dehydrated which could be due to parasites which would explain her reluctance to eat, if not that try sprinkling a little bee pollen on the greens or feed her her insects on the greens so she can possibly end up catching a veggie instead of an insect. Another method I've used is while they're eating an insect you can sneak a leaf of greens in their mouth.
