[Graham Purwatt]

with a black head,eats the hell out of leaves.i'm indoors in coco hempys never had these in 3 years of growing. any idea what they are?small like larvae but looks like a caterpillar.leaves black spots behind like excrement or something

about 1/4 to half inch long green caterpillars w/ dark brown heads is what I'm used to seeing. betcha they are from some dumb moth. you better get on top of this quick...once those boogers start chomping away at your buds, that whole bud will start rotting/dying.
