Criteria

I want to take a moment to state my criteria for including or excluding species from this project.

I want to be able to confirm herbivory in some way.

If an insect is just sitting on the plant, that does not necessarily suggest herbivory. It could be visiting flowers. I am not including instances of pollen or nectar feeding because this does not harm the plant.

If it is an adult that only feeds on Conium as a larva, I will not include it.

If the insect is on the plant and it is an herbivore with no other business being there, then I will include it. For instance, chrysomelids appear to be visit Conium but they are not there pollinating the plant. Leafhoppers and treehoppers also fit in this category.
