As an avid butterfly gardener, I often rear my butterflies from eggs planted on the host plants in my garden. I am baffled because I found eggs and two new hatchlings on the Forsythia bordering the woods behind my property. I believe these may be swallowtails, based upon their form and some internet images. But Forsythia is not listed as a host plant in my references. I have at least 20 eggs, some green, some clear white, in different stages of development.
Does anyone have any experience with Forsythia being a host plant?
Imagine, and my certified butterfly garden is a buffet of host and nectar plants !
