Ladybug or Beetle?

[Scarecrow]

Just found this section for garden pest's.

I have read that ladybugs are good for your garden. I have ladybugs or beetles on my pickling cucumbers and they appear to be eating the leaves. I haven't sprayed anything yet as I didn't want to run off what few bees that are visiting.










This damage is seen only on a few leaves so far.

Some other kind of bug but doesn't appear to be eating.



I have seving dust but haven't used it on the cukes yet.

Any suggestions?

Thanks,

Scarecrow
