Katydid crickets, for example, communicate by sounds with frequencies higher than 100 kHz, far into the ultrasound range.
Tettigoniidae, an insect family known in British English as Bush crickets
Because the flowers are made of a sweet chewable tissue (like the pulp of a fruit) they are much favoured by katydids (Tettigoniidae), whose feeding reduces the number of flowers available to be pollinated.
Similarly, the katydids, a group of grasshopper-like insects found worldwide, are nocturnal and use their cryptic colouration to remain unnoticed during the day.
