How to vary gray tree frog diet

[Treesniffer]

I feed my Greys silkworms along with Turkish Runners. wild caught moths and sometimes store bought Banded Crickets. The Silkworms are expensive and messy so I've switched to Butterworms which are incredibly easy to keep but like moths, too fattening. The Veterinarian warned me the moths carry parasites but I've had no problems with my Greys over the past 6 years. I feed them the moths about once maybe twice a week in the Spring and throughout the Summer, alternating with Turks, outdoor insects.
I could swear my Greys tap their fat little toe pads in excited expectation when I approach the viv with my captured winged trophies.
