Spider courtship boasts some of the most charismatic and strategic rituals in the animal kingdom: bondage worthy of the bedroom, percussive performances worthy of the drumline, silent sounds worthy of tradecraft. Still, arachnologists have documented those rituals in only a tiny fraction of the known 50,000-plus spider species, which hail from more than 100 families. Of the species whose courtships have been studied, most fall within just a few of those families, limiting how much arachnologists can glean about the evolution of mating across spiders as a whole.
