Sphagniana sphagnorum, the bog katydid, is the only species in the family Tettigoniidae (order Orthoptera) endemic to Canada.[1] It frequents black-spruce sphagnum bogs across the Canadian northwest from Ontario to the Yukon.[2] The two-part song of the males is remarkable among acoustic insects for alternating between two sound spectra: high audio sound frequencies are changed for ultrasonic frequencies every quarter second (Morris 1970). The forewings rub to and fro, drawing a scraper on one forewing along a row of teeth (file) on the other forewing and sending thin glassy wing cells into oscillation to radiate sound; two different regions of this file are used for the two spectra (Morris & Pipher 1972).
