OK, I put my pot out today, since it was sunny and warmer, and a gnat-sized little fly came buzzing by--suddenly, it gunned it straight for the pot and immediately dove into one of the traps!
The plant ignored it (too small, I expect), but 30 minutes later it was still running around contentedly on the edge of the trap, eating the "nectar" I suspect.
I'm thinking that there must be a scent component in the nectar--or could the gnat sense pure sugar at a yard's distance? Amazing!
Squirrel-haters--I put my pot inside a tepee (sp?) of thin bamboo rods, driven into the ground around the pot and tied at the top. They are about a half-inch apart, and should keep the little bushy-tailed varmints out while letting light in.
