    I have 3 of them now and not a single one is catching anything for weeks. I'm getting close to feeling compelled to feed them something I caught. There are plenty of insects in the garden, but no action near the VFTs and no closed traps.

    I saw one of those little insects that curl themselves into a ball when touched. I caught it and placed it inside one of the traps of one of my plants. It closed shut immediately and looked fine this morning. So at least I found something I can put on the menu when available.

    There are lot of gnats buzzing around them, but they are so small, I wonder how often they trigger a trap and what benefit the plant would get.

    VFT's are designed to *not* eat very small insects..
    the trap fully closing actually occurs in 2 parts:

    1. an insect (doesnt matter what size) brushes against the trigger hairs, triggering the trap.

    that alone isnt enough to "finish" the closing process and begin digestion..
    Notice at this first stage, there are still gaps in the trap..its not yet fully closed, its not "sealed tight"..the "teeth" are only intertwined loosely..

    2. if the bug is large enough to *not* escape, further movement by the bug stimulates the trigger hairs further, which "tells" the trap it has a good live bug, and "stage 2" can commence..the teeth will bend outwards slightly, the two halves seal their edges together, the trap fills with fluid, the bug drowns in the fluid, and digestion begins.

    If the bug is really small, like a gnat, it can easily escape out of the loose "cage" after stage one..this is deliberate, because it isnt worth the plants effort to digest something so small..

    also inanimate objects: rain, dirt, etc, that might accidently trigger a trap to close, wont continue to move, and so the trap will quickly re-open and wont waste any effort trying to digest a non-bug..

    Whether you believe evolution, "nature" or God created the VFT, its really an amazing system..
