Which Orthoptera can make crackling sounds while flying?

Within the order Orthoptera, the insects capable of producing a crackling sound—a process known as crepitation—while in flight are the band-winged grasshoppers (subfamily Oedipodinae).12

These grasshoppers possess stiff veins in their hindwings that generate this characteristic noise as they fly. When at rest, their brightly colored hindwings are concealed by their forewings, which are typically camouflaged to match the surrounding vegetation. The band-winged grasshoppers are the only group within the short-horned grasshoppers (family Acrididae) that produce sound during flight. A well-known example of this group is the Carolina grasshopper (Dissosteira carolina).12
