Why do crickets chirp?

Quick Answer
Male crickets chirp by rubbing their wings together to attract females and warn off rival males.
The Full Story
Crickets make sound through stridulation: a ridged 'file' on one wing is scraped by a 'scraper' on the other. Only males chirp, using different songs to call mates, court nearby females or challenge rivals. Crickets are cold-blooded, so they chirp faster in warm weather. Dolbear's law, published in 1897, even lets you estimate temperature from chirp rate.
Key Facts
1.Crickets hear through ear-like organs on their front legs.
2.Dolbear's law: temperature in °F ≈ 40 + chirps counted in 14 seconds (for certain species).
3.There are over 900 species of crickets.
