Caterpillars: Some unidentified ones doing their thing

Six photos of caterpillars I haven't been able to identify. If you know what species they are, please let me know in the comments.

A hungry one:

^{Olympus XZ-1, 28mm, ISO100, f5.6, 1/320s}

A translucent one:

^{Olympus XZ-1, 28mm, ISO400, f5.6, 1/6s}

Going Up: a tiny one scaling a big tree:

^{Olympus Stylus 1s, 42mm, ISO400, f4, 1/80s}

A hairy one coming for me:

^{Olympus Stylus 1s, 42mm, ISO400, f4, 1/60s}

Nothing to see, just a branch:

^{Olympus XZ-1, 28mm, ISO400, f8, 1/40s}

And finally, one pretending to be a stick, and maybe also pretending it just gnawed off a tree branch:

^{Olympus Stylus 1s, 42mm, ISO200, f5.6, 1/160s}

Thanks for watching!
