Insectivorous plants

I have quite a large collection of insectivorous plants growing in five  'bog habitat planters' on the patio. These are mostly Pitcher Plants, but there are several species of Sundew, Butterwort and Venus Fly Trap: all of these have had a terrific year! Whether it's because there have been lots of insects, or because the weather has been optimal, they have all grown larger than in previous years.
