In this shot the ambush bug appears to be stretching ... and what a cute little vest he has on. Then again maybe he is angry and is getting ready to zap me with Godzilla breath! Is it a bug or a very small dinosaur?
Seriously this bug has the ability to grasp prey with his claw like pincers and then impale them with his hypodermic like beak (rostrum). His antenna fold back into little grooves within the protective mantle that covers his head. The hind legs are ecquipped with hooks to firmly anchor himself when capturing prey. Ambush bugs routinely take down butterflies many times larger than themselves. They also eat bees and other insects that visit flowers.
