DH and I have been working on major changes to our back yard for the last year with focus on it being BF and bird friendly. Recently, a tiny black beetle devoured the leaves of each and every coreopsis we have, both front and back yard. Once I discovered what the culprit was, I sprayed those plants with Neem, being careful not to spray anywhere near blooms on other plants, and there is some regrowth now on the coreopsis. But will it harm the BFs or birds to use Neem in that manner?

Photo attached of foliage damage that I assume is some type of leaf miner but really not sure. I'm finding this down close to the ground on several plants.

I worry about using the wrong thing but feel I've got to do something to control this type thing or there won't be any flowers for BFs to nectar on. Would appreciate advice on this.

Thanks.
