Carnivorous close-ups

As I mentioned when I shared the photos I took in Evan's garden (here), I desperately need to figure out the finer points of taking photos with my COVID camera (so called because I purchased it as lockdown took place last spring, and then didn't touch it for months). One afternoon recently the sun and shadows provided such strong lighting conditions it was a fun time to work with it. Here is a Darlingtonia californica pitcher. The windows that confuse and exhaust the plant's victims "if I try just a little bit harder I'm sure I can get out this way..." are evident all across the top of the pitcher.
Moving to the sarracenia you can see the downward pointing hairs that make it difficult for the prey to climb out of the pitchers. Slide down so easily, then fight your way back out... 


I did a brief search to learn if the water that fills the pitchers in a strong rain plays a part in the process, but couldn't find anything to substantiate the idea. 
Please speak up if you know. I swear I once read something about the reflection encouraging victims to take the plunge.

These are such interesting plants.
I count myself lucky to be able grow them.
