Jim, Females can kind of smell or taste their host plants in the air from a great distance. You may have just gotten a stay female which threw of phermones and drew in males? Just be careful because the larvae develop inside the pod and will feed on the seeds inside the pod. Down here, yuccas are in almost every yard and roadside and the moths are common. My dad has Pipevine swallowtails butterflies which are not native to South Jeresy, but every year they fly in from northern Delmarva or PA where Pipevine is native and recolonize his plants. It is really amazing how they can sense the host and know where to go. |
