Cindi, I was setting them up in a nuc, adding feeder etc... and she would fly off then come back, fly off then come back. I have to admit a few of those times I would physically place her back in the nuc but she kept flying back and forth from the truck to the nuc.
The light was a little slow going on in my head about the lemon grass being in the truck box as I normally keep it inside my truck, so once I realized why they wanted to go to that spot the mystery was solved.
