These things are small. You can see them with a 45x loupe,, but to really make them out,, use a 60x. They actually bore in the stem and winter over inside infected stemage. Bud turn brown and dead... Starting at the lower middle spreading outward and upward. Matter a fact you could say it looks like rust too.. Next to impossible to control once flowering sets in. I made the mistake of using my soil again I think. But the best way to stop them is preventive. Some DE sprinkled around the soil will help. And if your in area prone to them spray your plants regularly while in veg up till 4 or 5 days into flower. Claims I hear is Green Cleaner from Old Stage is the best. Neem works, even Azamax while in veg.
Not sure if I posted this here,,, but there is very little info out there on these bastards but here's a fast read;

and I found one plant that had budworms. I did research and I found out that moths or butterflies lay these little round white eggs usually on the top colas. Those eggs bust out little worms that usually go inside the buds and they start eating from inside out. You can tell you have budworms when your pistils are turning brown too early. The caterpillars crawl across. If you miss that sign for some reason then youll notice that a part of a cola is slowly losing color and then it turns brown (like it has bud rot). Sugar leaves close to that area will lose color too. They will turn yellow slowly. Pry apart the bud in that area and youll find fucken tunnels where the worms bore through.
