I believe this is a Bladderwort Blooming...

I never noticed them before but they were blooming at a pond on Aug. 5 2019 in rural Norman Co. Mn. The flower was maybe between 1/2 and 3/4 of an inch. Had they not been interesting in shape, color, size etc. I probably would not have paid any attention. First time I seen this plant. I read it is carnivorous with small bladders which are inflated sacs that are triggered to ensnare tiny aquatic organisms. Interesting and when blooming colorful.

Aquatic carnivorous bladderworts (Utricularia species) catch prey animals with suction traps. High speed video recordings show that the plant "swallows" its prey in less than a millisecond!

The trapdoor morphology is optimized for a fast opening and closure, which we confirm by numerical simulations. It is an elastic valve that buckles inside (entailing opening) and then unbuckles (entailing closure). These precise and reproducible motions are coupled with a strong suction swirl causing accelerations of up to 600g, and leaving little escape chances for prey animals.

Plant die in extreem voedselarm water kan leven door het verteren van kleine kreeftjes in blaasjes die een vangmechanisme ontwikkeld hebben.
