What are these? The orange ones are about the size of a lady bug.
I love your field guide by the way, but this little group has me stumped.

Answer
Jeff:

Thank you for the compliments on my field guide.

The image depicts not beetles, but the nymphs (immature, juvenile, "babies") of some kind of stink bug, family Pentatomidae.

It is nearly impossible to identify nymphs of true bugs.  The adults are hard enough!  Do recognize that a small number of stink bugs are predatory, rather than pests of plants.

Cheers,

Eric
