Unfortunately I can not identify this plant. It catches small flies, attracting them inside the trap. Once they are in, they have to clamber up through the narrow canal (not wide enough to fly), that is densely planted with sharp trichomes and covered with sticky substance. After a few unsuccessful tries a fly usually surrender and fall into the liquid below.
Often you can see large ants waiting near the opening. They are secondary carnivores that successfully use these plant traps to have their own dinner. Those flies that manage to reach the trap opening will get caught by the ant.
