), Salvi was recognized as being the first person to publish an article about a tree cricket. His 1750 article was published 13 years before the first tree cricket was officially described (
Scopoli, 1763). The common name, sage tree cricket, is given because these tree crickets have similar coloration to the sagebrush host plants at Lake Annie.

No singing was detected during the daytime by either KS on two occasions or by NC on two consecutive days. In captivity, males did not start singing until dusk or later. The color of sage tree crickets allows them to blend remarkably well with the rabbitbrush and sage shrubs they inhabit. Shrubs were intensely visually scoured by NC, but no tree crickets were detected. Only with the use of sweep netting were tree crickets found by both KS and NC.</paragraph>
