I'm amazed and don't see how they know that they glow to the insects. You would think they would evolve to avoid these things. I wonder what a lightning bug would see if they landed on one.

A bug landing on one wont last long enough to see much except it's end. I wish we had some to reduce the flies and mosquitoes.

Loved, loved, loved the photos! Just googled the harmless sounding name, queen of hearts and got pics of carnivorous plant that can consume animal as big as rat. Yuck!
Thanks for sharing.

Rats . Bev how big, can they eat a tom cat sized rat if so let me know their names please . Rats, mice, mosquitoes, flies, etc. you name them we have them. By the way, our normal cats are afraid of our rats and if you don't believe me pay a visit to any dirty looking merchant ship. Bound to find some.

It is amazing how plants adapt and evolve!

The pics are fantastic, I have sundews growing down by the pond but I've never actually seen one capture a dragonfly!

Truly amazing, Larry. Thanks for the article.

The ultra violet thing isn't that terribly uncommon on flowers, but I would think leaves are another "animal". Did the literature say anything about testing for pitcher plant flowers and/or different species? Love to see the the original work if you have a link.

My initial wondering with the pitcher plant is: why doesn't the UV color extend inside the pitcher?
But with further thought, it's more likely that once the an insect is attracted to the lip, scent might take over as the primary lure.
