Thank you for submitting this firefly observation! Several things point to the species Pyractomena borealis (common name “Spring Treetop Flasher”):
-the raised line on the headshield (pronotum) is a trait shared by all fireflies in the genus Pyractomena
-the early flight season for this region
-robust size (this is the largest Pyractomena firefly in the region)
-narrow yellow borders on the elytra (forewings)
