I have a pretty decent collection of 6 flytraps and a bunch of other carnivorous plants in my terrarium, all of which are good fun, but the VFT are the most entertaining.
My oldest plant - Mr. Snappy - is four years old and is doing great.
First off, the plants don't need to 'eat' all that often. They photosynthesize like any regular plant (They use their traps up to about 5 times, then they kind of fold out and flatten to work as a regular leaf).
It is important to give them small insects such as mosquitos. Anything larger and the prey will begin to rot (Turning the trap black) thus killing the trap and generally not doing the plant any favours. The plant takes about a week to digest it's prey, after which the trap will reopen with the exoskeleton of the prey remaining (you can remove these carefully with tweezers).
You might have to feed them manually. I fed mine ants and stuff from outside. Other people say ground beef works pretty good.
Ground beef is way too fatty and will kill the plant. Also, the prey needs to be alive and moving for the trap to work.
Each trap has several 'hairs' on the inside that act as the trigger for the trap. These are stimuated by insects moving, but can also be stimulated accidentally by rain/dirt in the wind, etc. To combat this the plant goes through two stages when trapping. First, when the 'hairs' are stimulated, the plant closes lightly with the 'fingers' of the trap interlocked to prevent escape attempts. If the hairs are further stimulared after this point, the plant then closes tightly, forming a seal and introducing it's digestive goo.
Be careful. I don't know much about them, but if they reproduce, your yard could look scary!
VFT's spend most of their energy flowering. They produce a long stalk ~8" long with a bunch of white flowers at the top. Although pretty, this serverly weakens the plant and they ofen die as a result of flowering. It's considered good practice to trim these flowing stlaks as soon as you identify them. I've let Mr. Snappy flower a couple of times and it's always been pretty weak after for a couple of months, but a lot of sunlight/water and a few good meals and it's been OK since.
Also, once germinated it takes ~7
years for the seed of a VFT to become a fully operational plant, so you're not looking at having a carnivorous jungle in your garden any time soon.
Just don't stick something else in there... they can leave a bruise.
Ok... it's pretty weird that you even thought of this.
they grow naturally in the carolinas don't they?
Yeah, and strangely ONLY in the South Carolinas... nowhere else. Some people claim they came down in a meteorite... I'm dubious.
Either way they're bog plants, used to living in very damp marshes and so should be kept in an environment similar to this to maintain their health.
I like my plants a lot, but they do need a lot of care. Most people find that theirs will die within six months or a year of them owning them.
If you're looking for plants that consume larger quantities of insect, go for a
nepenthes alata or similar. Although the traps are passive (don't actually move) they produce many of them and can consume much larger insects (or even small reptiles like frogs).
Enjoy.
