These tiny bugs are currently all over the radish leaves in my garden, and I'm curious to find out what they are. They behave like flea beetles -- they jump quickly out of sight when they're disturbed -- but they don't look like the flea beetles I had in my garden last year. The flea beetles I'm familiar with are black and shiny with a clearly hard shell and hind legs obviously suited for jumping. These bugs, in contrast, are dark brown with softer-looking bodies and no "flea-like" hind legs that I can see. They don't seem to be doing much damage to my plants, but I've never seen them before this spring, and I'd love any suggestions about a potential ID!
