This is what I was after! The pitcher plant, sarracenia purpurea, in abundant glory.

(Provincial flower of Newfoundland and Labrador, by the way.)

“Classified as carnivorous rather than insectivorous because consumption includes not only insects

but also isopods, mites, spiders, and the occasional small frog.”

 Small frog?!!

It’s not the flowers, but the leaves at the base of the plant that are the trap.

The hairs in the ‘pitcher’ act like a spike belt preventing prey from escaping.
