I believe it IS legal to collect Venus Flytraps from the wild, IF (and only if) it is your own property. Don't quote me on that. The only CITES laws/restrictions I've really had drilled into my head are ones concerning Sarracenia jonesii. And richjam is right. Do what is ethical as well as what is legal. Venus flytraps are a vulnerable species and many other carnivorous plants are critically endangered. The genus Aldrovanda originally had eighteen species, but now the only one left is a vulnerable species as well.
