Any idea on what is doing this to my cantaloupe plant? Looks like an insect but haven't seen anything in the plant when I check.
Yup, I agree with AJBB, it looks like leaf miners to me too. I usually don't worry about them if the plant is generally happy. I see a nice looking cantaloupe in the background. I'm envious! What variety are you growing and are you happy with it overall? Happy gardening!
