Since that time we have learned much about the biochemistry and physiology of firefly luminescence. The firefly lantern has even become a tool for the assay of the major energy compound of cells, ATP. The study of flash communication in many firefly species has revealed that timing relations between the flashes provide the necessary information in this system for sexual and species selection. Nowhere is the ability to control the timing of flashes more strongly exhibited than in the synchronously flashing fireflies of Southeast Asia. These fireflies provide the ultimate test of our biochemical, physiological and behavioral theories of firefly flash communication.

SYNCHRONOUS RHYTHMIC FLASHING OF FIREFLIES. II. JOHN BUCKLaboratory of Physical Biology, National Institutes of HealJh, Bethesda, Maryland 20892 USA ABSTRACT Synchronizedflashing by males of some firefly species involves a capacity for visually coordinated, rhythmically coincident, inter-individual behavior that is apparently unique in the animal kingdom exceptfor afew other arthropods andfor man. This paper reviews (1) diverse communicative interactions that have evolvedfrom elementary photic signals, (2) physiological mechanisms of synchronism, and (3) theories about its biological meaning. Work of the past 20 years shows that flash synchrony is widespread geographically and taxonomically, appears in an astonishing range of spectacular display types, utilizes several neuralflash-control mechanisms and is pervasively but enigmatically involved in courtship. No proposedfunction for synchrony has been fully established but theory and physiology concur in indicating that synchrony aids male orientation toward the female, female recognition of male flashing or both. Increased mate choice for the female is one likely ultimate benefit.
