Brush-legged Wolf Spider

The Brush-legged Wolf Spider is a remarkable species where males bear tufts of dark bristles on their front legs used in highly visual courtship displays — drumming and waving their decorated forelegs to attract females. Research shows females use both visual and seismic signals to evaluate males. Females lack the leg tufts entirely and can tell male quality from the combination of leg tufts and leg tapping signals.
