Kinda like this one?It's probably one or more light green, slender caterpillars that eat cannabis. They are hard to find... camouflaged.

Caterpillar eating leaf. Out of focus. Plant was culled during the great 2021 grow disaster.
Found this on one plant last year. I kept watch for a day. The caterpillar moved off somewhere within an hour or so of taking the picture. Never did end up with any sort of insect problem, just mold and mildew like so many other outdoor growers mentioned.
