Tree crickets (Oecanthus spp.) are slender, pale green to white crickets that live in trees, shrubs, and tall vegetation. They are among the most acoustically sophisticated insects in Arizona — males produce a pure, melodious tone, and large groups often synchronize their calls into a unified chorus. The snowy tree cricket (Oecanthus fultoni) is famous for the 'Dolbear's Law' relationship between its chirp rate and ambient temperature, making it a natural thermometer. Tree crickets are found throughout Arizona wherever suitable woody vegetation exists, from desert riparian corridors to suburban gardens and orchards. Females insert eggs into plant stems, which can cause minor damage to ornamental shrubs and fruit trees. They are not structural pests and are generally considered beneficial due to their role in food webs and their aesthetic contribution to the soundscape.

Male crickets produce their characteristic chirp by rubbing their wings together (stridulation) to attract mates. Reducing outdoor lighting (which attracts crickets), sealing entry points, and eliminating harborage areas near the home are the most effective ways to reduce noise.
