In August 2015, the first population was found in mainland England at Dungeness in Kent, where hundreds of males were present.

The chirp (or trill) of a tree cricket is long and continuous and can sometimes be mistaken for the call of a cicada or certain species of frogs.

Due to this, female tree crickets have tympanum (hearing organs) that can receive a much wider range of frequencies than most other insects.

[6] Female tree crickets seem to prefer calls at the lower range of frequencies indicating the presence of a large male.

Shortly after copulation the male tree cricket secretes a fluid from the metanotal gland located between its wings in the thoracic cavity.

[9] After remaining dormant for the winter, the eggs hatch in the spring and the young tree crickets begin feeding on aphids.

The snowy tree cricket (Oecanthus fultoni) is known for having a chirping rate highly correlated with ambient temperature.
