A few interesting points relating to when and why crickets sing:
- Good singing is in inheritable trait that is passed on.
- Crickets need plenty of food when young to become the good singer that they are genetically predisposed to be.
- Small male crickets need to sing to be able to mate, whereas large males mate more if they don't sing.
