funny slug like trail on leaf?

[Johnny5]

Hello

Hope everyone's cool...
I ve just woken up and had a good look at my plants while watering them, they are 10 ten white russian about 35 inches high.
They have got something funny on there leaves, it looks like a slug trail kinda
but not as thick. It sort of shines abit of the leaves...
I noticed a few spider mite aswell would they cause this, from my knowledge they don't???
So I was wondering if anyone else knows what it can be?

Thanks for any input

Get neem oil. It kills all except slugs. Use other slug remidies if there are slugs.

Those twisty trails you described are called leafminers. They are the larva or maggots of a certain type of moth, fly or beetle. They tunnel between the top and bottom leaf egdes, and the destruction they caused can cause young plants to be severely stunted or create lower yeilds in older plants. They are PAINS IN THE ASSES!! The neem oil will discourage the adults from biting into leaf or laying eggs under leaves, but not guarenteed to prevent. Best method I have found is physically removing larva from leaf with tweezers (look for a slightly orange bump in the trail) and spraying with neem oil and then using row covers or netting to prevent them from returning. They are notoriously hard to get rid of, and another method you may use is distracting them with other plants they like, say like eggplant, lambshank, or columbine. Even basil or celery plants, which they supposedly love will do the trick. So will sticky fly tape near plants, perferably the color yellow, to which these suckers are drawn. Good luck.

Dammit I was going to say some sort of leafminer.
Could be thrips. Is there black shit in the 'shiny' stuff?
