We are within two months of the start of the singing insect season in the Chicago region. Opening day is marked by the first displays of the green-striped grasshopper.
These grasshoppers get their early start because they overwinter as nymphs, and so can mature quickly in the spring. Their displays, which qualify them as singing insects, consist of short flights in which they rattle their wings, producing a buzzing sound:
That this is a display is demonstrated by the fact that when they are flying to avoid the pursuit of a possible predator, they do not make that sound.
