Something is eating tomato plant leaves and also my lavender and mint. The leaves look like lace, they are so badly eaten. I have seen two very small green caterpillars near the mint but not near the tomato plant. I have seen white butterflies large and small. Something has now started on my basil.

Neem Oil is a good treatment for most insects and it also works as a fungicide. It is safe for people, pets and bees.
Here is several links for you that may help with identifying the insects.
