The Harrisburg Mayflies identity pays tribute to the local lore of Pennsylvania’s capital. Every summer, the Susquehanna River transforms into a stage for one of nature’s most fleeting yet spectacular performances — the mayfly hatch.

As dusk settles over Harrisburg’s bridges, thousands of mayflies rise from the water, filling the air in a shimmering swarm that signals renewal, resilience, and the brief brilliance of summer nights along the riverfront. The Mayflies identity captures that same spirit — a nod to the city’s connection to the Susquehanna, its lively community gatherings, and the reminder that even the shortest moments can make the biggest impact.
