With the arrival of spring it is time to conclude this winter series. Plenty of sound recordings remain to be shared, so I’ll resume Sound Ideas in November or December. The appropriate finale is a recording of the first singing insect we hear each year in the Chicago region, the greenstriped grasshopper. Given the late spring, I am not expecting the first of these before mid-May. I have not found a recording of this species elsewhere:
The buzzing sound is the rattling of the male’s wings (crepitation) during short display flights. If you have the volume turned up you may get the impression that this is a loud sound, but it is not. Though it is easy enough to hear, you may well miss it if you are not paying attention to the sounds around you. This common grasshopper occurs wherever there are abundant tall grasses, including open wooded areas, though the greatest densities are in meadows and prairies.
This is our earliest singer because it overwinters as a nymph, and so can complete its maturation early in the season.
