Any Idea What These Two Critters Are? (pics)

[rnewste]

I've been closely inspecting my tomato plants this afternoon, and I found these two guys (and some of their mates) on 3 of my Goose Creek plants (at least, they have good "taste").





This one seems to be a brown color, as opposed to the crimson of the first critter:



Before I go Rambo with the Insecticide spraying, can someone tell me what these guys (or gals) are, and how best to treat them to a dirt-nap?

Thanks for your help,
