Cicada On My Pear Tree

July 21, 2017  •  Leave a Comment

Yesterday evening I found a Cicada on the trunk of my pear tree. It was low to the ground so I went and got my camera to get a few photos of it. It stayed in the same spot for a few minutes and then it climbed higher into the tree.

The Cicadas have been noisy the past few days here in my yard since the temperature has been in the high 90's. They start emerging around here about midsummer.

Cicada Facts

  • Male cicadas have a noisemaker called a tymbal below each side of the anterior abdominal region.
  • The tymbals are structures of the exoskeleton formed into complex membranes with thin, membranous portions and thickened ribs.
  • Contraction of internal muscles buckles the tymbals inwards, thereby producing a click; on relaxation of the muscles, the tymbals return to their original position, producing another click.
  • The male abdomen is largely hollow, and acts as a sound box.
  • By rapidly vibrating these membranes, a cicada combines the clicks into apparently continuous notes, and enlarged chambers derived from the tracheae serve as resonance chambers with which it amplifies the sound.
  • Partly by the pattern in which it combines the clicks, each species produces its own distinctive mating songs and acoustic signals, ensuring that the song attracts only appropriate mates. (Wikipedia)
