Carnivorous plants come from all over the world, from North Carolina (Venus Flytraps) to Australia (Cephalotus). 

Some are tropical and others freeze half the year, but the one thing they all have in common is that they consume insects to survive.

They are usually found growing in either very fast or very slow draining soil, where nutrients are unavailable or move too fast through the soil. So they’ve evolved to consume insects to make up for a natural void in nutrients and minerals. 

Most seem to enjoy at least some humidity and bright light.
