I have some aphids on the tomato plants. I gave them a good spraying with the hose today and knocked off most of the small white and green ones. However, there are a number of larger bugs of some sort remaining that I don\'t recognize. They hold on pretty tightly, so to remove them I need to use a brush or something.

I\'m unsure if they are a problem or not. I can\'t specifically see any damage from them, but there are quite a few so I want to ID them before doing anything.

The two images are attached, the second the best close-up I could do.
