I've done very limited reading, so far .. but have seen a few of these small sized 'catepillar' similarities .. referred to, as some type of catepillar 'slug' !

Also of note ... I've found some relatively small green ones .. on the INside of my butter bean pods too!!! Eating the beans !!!! Think what ever the varmint is - lays its eggs on the bean pods, and the eggs hatch and eat into the shell .. to consume the beans. And, certainly canNOT be a 'good' thing tho' ... ! ! !

I could only imagine that yours (in your pic) .. is doing the very same thing ...
