Many butterfly watchers across Pennsylvania, even those with pollinator or butterfly gardens or fields packed with butterfly-attracting wildflowers, have reported a noticeable decline in the big showy butterflies like monarchs and swallowtails, this summer.

Some have seen a bit of a resurgence in their backyard butterfly numbers later than normally expected in the past couple weeks. But overall summer 2020 has seen fewer butterflies in many parts of Pennsylvania.
