We are at a point in the season where the spring-singing insects are finishing, and the early summer brings new voices to the chorus. Green-striped grasshoppers seemed to tail off rapidly in their crepitating flights this year. I have heard very few in recent weeks.
The male green-striped grasshopper usually is brown. He’s the one who does the displaying.
The object of his displays usually is green, and a bit bigger than him.
Roesel’s katydids rapidly are increasing the number of buzzes they are contributing to the meadows and prairies.
Note the blur in the wings as this short-winged Roesel’s katydid sings. Some individuals have much longer wings.
Over the weekend I heard first songs from three additional species: Linne’s and dog day cicadas, and the gladiator meadow katydid.
This was one of several gladiators singing beside the Regional Trail in south Blackwell Forest Preserve Saturday evening.
Those Tibicen cicadas, especially, characterize the sound of summer for me.
