Hi. This is my first attempt planting a garden. I started everything inside from seed back in Feb and all has come along beautifully so far. (miracle of miracles if you knew my history with houseplants). A big rain came through last night and today I found a bunch of these bugs on my tomato plants. I scanned the first few pages of the bug pics forums before deciding it might be quicker and safer to ask here for assistance. My garden and I live right on the TX/OK border - straight south of Okla City.
Any help identifying is greatly appreciated. Oh - and maybe the best way to get rid of them?
Thank you.
