What is this on my pepper plant?

Everything is moving along quite swimmingly, but I can't help but assume that this squiggly stuff is not a good thing. It's on my Chinese 5 color pepper plant. Any help and advice would be GREATLY appreciated! I need to know what it is and how to treat it please. (If you click on the picture, it will enlarge it)



Also, am I correct to assume this is an aphid? This would be the first one I've seen...


And...yet another potential problem/deficiency. Any identification/advice would be FABULOUS! This is also on a pepper plant.


Ok, on to the happy stuff...

My onions are looking awesome!


My sweet peppers (California Wonder) are doing great


Eggplant is looking good


A very happy tomato plant


Peaches




Bodie is enjoying the warm (horribly hot) weather


Happy Gardening!
