Don and other interested list members,

The species in question is Passiflora foetida, which has sticky bracts
that do catch and hold small insects. More research is needed to
establish whether or not the plant really can be considered carnivorous.
There are a few other species of Passiflora with similar bracts, but I
have not heard any speculation about carnivory with regard to them. P.
foetida occurs naturally in South and Central America and the West
Indies, but not in the Continental U.S. as far as I know. The species
you have in Oklahoma is most likely P. incarnata, although there are a
few other possibilities.
