Not the Pinguicula. Not too fond of them, they aren't as pretty. Although, my brother is one of, oh, three people who have ever seen a certain species of Pinguicula. Fun fact of the day.
If you're thinking larger flies, moths, or wasps, a Sarracenia (rubra, for example) does a surprisingly efficient job.
Venus fly traps don't works as well for fruit flies. So yes, some species of Drosera, or sundews with the little hairs with beads on the ends. Those are my favorites. Excepting the Darlingtonia californica.
The cat only eats plastic?
Shame on you.
