This is a previously unpublished picture I took of what was left of a poor hummingbird after being attacked by an Arizona Bordered Mantis. It was found dead in the feeder with its breast eaten cleanly out in a circular pattern. I had seen the mantid on the feeder and assumed it was just eating bees.
I went into the house and came out an hour later to find this. The full-grown mantids usually show up in late summer. I now relocate them to the bee dishes or across the street. The one below was well fed on bees and showed no interest in the hummingbirds. I would have stepped in if necessary.
