Pteroptyx is a genus of fireflies in the subfamily Luciolinae found in Southeast Asia. It has long been noted for the ability to perform synchronous flashing, though not all species synchronize. These synchronizing species have been found on so-called 'firefly trees' and created a growing firefly-watching tour industry in some regions. Species of the genus have been identified in Malaysia, Thailand, the Philippines, and Hong Kong.
