I think it is a stink bug but is it a good bug??? I am very new to this.

Thanks,

That could be any one of many insects that have that shape, some are beneficial, some are innocuous, and a few are destructive. What are you seeing this wee bugger doing? Is this gal doing any damage to your plants? Is that damage of such an extent that something must be done? If no, or very little, damage is seen there is no reason to do anything at all about this wee bugger.

Sure looks like a stink bug to me. I've never seen the striped legs but the shield shape is unmistakable. They probably won't do a number on your leaves but your fruit is another matter. They decimated my tomatoes this year. Anywhere they stick their pincers in and suck out the juice becomes a brown spot that gets bigger...and bigger...even after the bug is long gone. I'd get rid of it.

Since there are Predaceous Stinkbugs, stinkbugs that eat other stinkbugs, you want to be sure you know what one looks like and can properly identify one before killing off any stink bug, especially if you're are not seeing much plant damge with that insect in your garden.
Far too many people think the only good bug is a dead bug.

Thanks for the help. I have found the type of stink bug this is, but can not remember the name... not a good guy.

I thought the brown ones of these above pictures fellas are squash bugs?
