Q.calla lilies have dark brown streaks in the leaves
My yellow calla lilies have dark brown streaks in the leaves and I’ve searched the internet and can’t find an answer as to why? Also, something is eating my leaves and I would like to know what I can put on the soil to kill the bugs/caterpillars. Thank you.

It actually looks like you may have a sport. That streak does not look like damage but rather a natural color variation in the leaves. Sports are a genetic mutation that can sometimes result in some pleasant variations in a plant. To be honest, it might be fun to see if this trait persists from year to year and you would have a unique variety.
