Larva with patterned green back?

[tjc1]

Took off the bottom board to clean it of dropped winter sugar, etc., and found on the screen a recently dead larva, about an inch long, with a dark green zig-zaggy pattern on the back. Assumed it must be SHB or waxmoth larva, but the photos I've seen of those on-line look all-white. Anyone have any insights? Wish I'd taken a photo...

Edit: I found it on a photo of the bottom board - not very clear, but ...

It is butterflye's larva.

I have met one kind of butterfly larvaes near my hives several times and I suppose that it is some kind of predator.
These larvae seek for shelter too and it may be accident that it is inside the hive.

Larva seems to live outside because it has camouflage on.

Looks like what we call a cut worm.
It's a moth larve.

wax moth and hive beetle larvae are smaller than that.
