Everything was fine yesterday but today one branch of my multi-specie Pluot
was
all but stripped of leaves (the others had nothing)

Critters are just over an inch with stripes from front to back, over all
they
are greenish/grayish.

Plucked them and sprayed with a orange based organic soap.

Hope I got them all, but are they likely to attack my cherry tree? And what
might they be and what's the best way to deal with them

If it helps I'm zone 9 or 10 and the weather is finally changing
I concur with Steve P. They are quite likely to be "fall army worm". It's
that time of year.... I'm on the zone 9a/b cusp in peninsular FL and they
have
begun to appear on my tomatoes. If you catch the infestation early enough,
thumb
and forefinger work well for eradication. Otherwise, off-the-shelf Btk is
effective. One application in the evening usually is sufficient and residue
may
be rinsed from plants the following day but, strictly speaking, rinsing is
unnecessary.

that's very close, but I am unwilling to categorically say that's what they are.
The stripes look a little wrong and the color is a little off, but pretty close

but then I'm getting old and getting cataracts. lol
