For those who asked, yes there are a few more Mantrap Lilies around.
Specifically, in the Booger caves after you insert the eye and the floor opens up - and may be a few wandering around the islands around Brimlock Roon. Just remember to save often and you'll be alright. It is a nice challenge, they don't scare like the first encounter. . . have fun!
Hope I didn't spoil anything.
