What's this on my cucumbers??

I have three picklebush and 2 burpless bush hybrids sharing an 18-gal tub with a wire teepee and another picklebush alone in a small tub. I think they're doing fine...I've picked 10 cukes in the last couple of days and there are tons of male and female flowers and lots of bees. I mentioned the other day that there are also TONS of tiny ants but I've just been ignoring those.

I've noticed that the undersides of the leaves have these little spots though and I'm not sure what it is.

I've also noticed what I assume is some kind of poop on some of the leaves and flowers:

The one that's in the little pot by itself seems to have something chewing on the leaves just a little (ironically, this one doesn't have the spots on the leaves or the poop) and lots of the little female flowers and baby cukes seem to be drying up. I had attributed that to the fact that vines are just hanging there and it's harder for the bees to get in there to the flowers but now I'm not sure.

The big one looks healthy but now I'm wondering

There are some kind of beetles but I haven't been able to match them to any pics online and of course, I couldn't get a clear pic when I was out there just now. I'm not sure if they're good or bad. They're kind of flat and shaped like a pentagon but not distinctive markings.

Any thoughts? Should I leave well enough alone or do I need to do something before things get bad?

Looks like a mix of some type of fly and green aphids. The poop is most likely some type of Caterpillar. I use a homemade insecticidal soup that seems to have worked well against aphids and flys. (I added the link for the recipe for the insecticidal soap to this post)

The plants look healthy though. I wouldn't worry too much.

Here is a link that might be useful: Soap Recipe

In lieu of the soap spray, you can wash off the leaves and stems with your hose. The aphids get knocked to the ground and can't get back up on your plant.

Thanks for that link! I put up a trellis for the little guy tonight and tried to stretch him up it a little. He's not very happy with me right now but hopefully when the sun comes up he'll see that I did it for his own good and forgive me. :) Am I the only one whose plants have personalities? I think I need to get out more often!

I'm going to just hose off the big one for now and keep an eye on it but I'll definitely try the soap if it gets any worse. Beetles munched my strawberry leaves almost to death and by the time I caught on, it was too late which is why I got a little nervous.

I saw a few ladybugs yesterday and they usually swarm here in the fall so I'm hoping they'll help me deal with the aphids!
