Praying Mantises kill Hummingbirds.
That, I didn’t know
Everything in nature spends every waking hour killing something or attempting to expand its habitat at the expense of every other living thing.
Only when there are Hummingbirds around. Preying Mantis are really cool insects.
Most species of praying mantises are not big enough to kill a hummingbird. There is one exception that I know of where the female is large enough, and has been photographed in the act, but seldom does so since there is so much other prey available.
There is an invasive Chinese mantis species established in the US and if memory serves, that is the one that is large enough to capture a hummingbird.
I had 4-5 hummingbird feeders hanging off wood planks & one day I saw a hummer hanging upside down in a bush underneath my feeders. Saw that 6” mantis were hanging off my feeders trying catch them. Started researching and they’re are videos on it.
I removed the boards and replaced with metal hangers and the problem stopped. I had so many hummingbirds, I took a picture and sent to an expert and based on the number in the photo, they estimated we had 2-300. They were going through about a gallon of sugar water everyday.
