Can you catch her eye with the feeder(s), then put them in the cup and back away? (Or show her the cup containing feeders, then back away?) I don't know that they're ever going to smell the insects, or come to the sound of chirping crickets/wriggling insects (mine never has); they have to see the bugs to know they're there. Could the feeder cup be placed somewhere your female would normally frequent? (My cup hangs from a vine that is part of the chameleon superhighway from one desirable perch to another, so he has to walk directly above the cup, at which point he sees the insects.) Once they know the cup is there, and what's in it, they learn quickly to return to it for food.
