That does look a bit like a flea!
While photographing last week, I found a shiny green beetle that was kind enough to let me get some shots of it. I found it curled up and hiding in a plant stem and managed to annoy it enough that it started walking around.
When it came time to identify this beetle, I didn’t have much hope. After all, there are thousands of “shiny green beetles” out there and I didn’t have too much hope of figuring out what this is.
To my surprise, I think I do know what this is. It looks a lot like a flea beetle (family chrysomelidae, subfamily alticinae). I am not 100% sure, but it does look awfully like a flea from the front – doesn’t it?
