We just had a, kind of, similar sighting here. More than we've had in the past.
Apparently, it is hatch-out time for our crickets, and there are teeny, tiny crickets all over the place.
There was a container that had collected rainwater in it yesterday, and a little cricket got caught in it.
We put a little piece of cloth in, which he grabbed onto, and pulled him out, then let him dry in a safe place.
So, not a grasshopper but a similar mini all the same!
