Making the best out of the Spotted lanternfly (SLF) invasion. Specimens collected by us in our area in the summer 2025 & 2026 are being used in educational activities for staff, students, interns, volunteers, and the public at large.

We held a mini insect mounting workshop and built educational displays and hands-on activities to inform the community about the species.

We’re frequently sharing our experiences with the species on social media.
