Insect Identification Help (pics)

[lapk78]

First, let me admit to being somewhat of a noob, so if this is a dumb question, let me appologise in advance. I've done some research, but can't identify these particular bugs.

Just a few days ago, I discovered tiny holes on the lower leaves of my tomato plants which I'm growing in EarthTainers on my 2nd floor apartment balcony. Upon closer inspection, I saw very tiny, green caterpillars were the cause of the holes. The caterpillars are about 1/8 " long.

I removed (smooshed) as many as I could by hand, then I sprayed the leaves with Garden Safe brand Insecticidal Soap which did kill the caterpillars.

Over the next few days, this same scenario repeated itself, but the holes in the leaves were slowly getting higher on the plants.

Does anybody here know what I'm dealing with? What action should I take? Please help. Thanks in advance!
