Well it is touf to say because lots are good moth catchers but i would have to say sundews (Drosera) and it is REALLY hard to get the EXACT ONE that is the best but i would have to say Drosera filiformis, Drosera indica, and Drosera regia but regia is pretty exspensive so i would have to go more on the side of Drosera indica if not Drosera regia and they all curl around their prey. So if you were to start off from seed then i would do Drosera indica because it sprouts and grows FAST so i hope this helps.

I'd have to say none. I've never seen any moths caught by my plants. I don't think they're attracted to the scent. Most carnivorous plants catch scavengers or predators not pollinators IMO.

I agree that my Drosera filiformis plants have caught a lot of moths. But that has been outside.

Pretty much any large sundew will do. I see a lot of moths in my filiformis as well as cape sundews. Forked sundews (binata, multifida, dichotoma) also catch them often.
