Sound Ideas: Texas Bush Katydid

by Carl Strang

Our bush katydids, genus Scudderia, have some of the most interesting song variations of all our singing insects. They include two “counting” species, with increasing numbers of syllables over a sequence of songs. Often they have more than one song type, and this is true of today’s featured species, the Texas bush katydid S. texensis (back in the days of the Bush presidency I was fond of pointing out that there really was a Texas bush katydid).

The following recording includes two of the 3 song types: single clicks, which I seldom have encountered in the Chicago region, and the characteristic dusk or nighttime song, a series of quick buzzes.

During the day this species produces a very fast, 3-syllable call which I render “dig-a-dig.” It is similar to the daytime song of the broad-winged bush katydid, but the latter has more syllables (sounds like 5, usually) and they are less distinct because they have a lisping quality.
