Sometimes, to find true love, you have to stand out from the crowd. Sometimes that involves using a leaf as a megaphone to make your mating call louder. Sometimes you're a tree cricket. ValentinesDay
Biologists first spotted crickets creating leaf-speakers,, and singing from them, or baffling, in 1975. Since then, the baffling behavior has been reported in two other species, but wasn’t clear exactly how it benefits individual crickets.
Deb, then at the Indian Institute of Science in Bangalore, and his colleagues first looked for any commonalities among crickets who use baffles. Only 25 out of 463, or 5 percent, of crickets observed and individually marked at field sites outside Bangalore were seen baffling. On average, baffling males were smaller, and called more quietly when not baffling.
It’s unclear why females don’t seem to notice that they’re mating with a smaller male, though it’s not necessarily surprising. “They’re not wrapping their little arms around males to see whether they’re big or small,” Zuk says. “Maybe there’s something in the song that signals ‘go ahead and have more of this guy’s babies.’” males have evolved a remarkably effective mating strategy, Zuk says.
