To contrast leaf-miners with other agricultural pests – before the leaf-miners came to town, we also had a bunch of Giant Swallowtail Butterflies (https://en.wikipedia.org/wiki/Papilio_cresphontes) that made their homes in our citrus trees. Their caterpillars never did too much damage, and the annual presence of huge, striking butterflies was pretty enjoyable.

Sadly, I think our (organic) efforts to get rid of the leaf-miners also killed off the butterflies.
