Hi again warpig,
It depends on how big the meal is. Sometimes they can re-open in 3 or 4 days....sometimes 10 days.... As long as the traps are still green (or red), they're still healthy. It just takes something I have very little of.....Patience!
I have to disagree about the ants....They catch a lot of them in the wild, one would think, since they are rosette plants. Mine frequently catch ants on their own, and seem to benefit from them.
That said, you don't want to put one of those almost-microscopic ants in a one inch trap, but as long as you use common sense, ants work just fine.
I have fed my vft's some huge carpenter ants, they havent opened yetand its been about two weeks. One of them is getting a little blackening on the lower part of the leaf ( not the trap itself) is that bad. And one more question i fed one of my vft's a mayfly looking thing and i think some bacteria formed because now the trap is rotting just where the bug is, should i wait until i turnes completely black or not?
