Tomatoes – pests

QuestionsTomatoes – pests
Ray Dunford Staff asked 13 years ago

For the first time ever, I have had catterpillars in my glasshouse (I assume butterflies made their way in and laid eggs although I saw none??) I have noticed a lot of small groupings of little green and/or black pellets on my tomato plant leaves and window frames of the glasshouse…are these the droppings of the caterpillars?
