TL;DR

Static plumage can be faked; a precisely choreographed dance cannot. Jumping spider courtship combines 20+ signal elements that only intact nervous systems can coordinate.

By Alex Denne

Documented one of the most complex multimodal communication systems in arthropods—demonstrating how dynamic displays signal quality more reliably than static ornaments because coordinated performance requires intact neural processing.

Key Findings from Elias et al. (2012)

  • Vibratory songs contain up to 20 elements organized into functional motifs that change with courtship stage
  • Visual displays are temporally coordinated with substrate-borne vibrations
  • Multiple independent mechanisms produce different vibratory signal components
  • One species (H. borealis) has secondarily lost complex display behavior
  • Display complexity is analogous to musical composition with orchestrated elements
