Identification: Length–16 mm. No other U. S. cricket produces uniformly spaced chirps at a rate of less than one chirp per second. Antennal markings similar to those in the photograph above.

Habitat: Disturbed areas of mixed growth forms.

Season: The only records are from May and June, but there are no negative data for other months.

Song at 25°C: A highly regular, slow, continuous series of long, melodious chirps. As shown in the spectrograms above, each chirp usually begins with a pair of pulses that is followed by a series of pulse triplets. Most chirps total 20 or 23 pulses.

Song data: See Walker & Collins (2010).

Similar species: Two other species of the Oecanthus riley species group, fultoni and rileyi, occur in the U.S. but each calls at chirp rates several times as fast as alexanderi and neither occurs in south-most Texas.

Remarks: Nancy Collins, a nurse in Racine, Wisconsin, developed an interest in Oecanthinae in the summer of 2006 and soon pursued that interest with vigor and to good effect. For example, she founded a Tree Cricket Appreciation Group on Facebook (currently with 17 members) and authored a
