We present evidence for the occurrence of chimera states within swarms of synchronous fireflies. Using 3D reconstructions of the swarms, we show that different groups flash with the same frequency but with a persistent delay between them. These subpopulations appear spatially intertwined, with only weak signatures of clustering or correlated velocity. We discuss the implications of these spontaneous, self-organized chimeras for the structure of firefly social interactions and future theoretical paradigms.
