Fascinating Secret of Locust’s Knee-Ears

When we think about insects, our minds often conjure images of small, seemingly simple creatures.

However, the world of insects is a treasure trove of astonishing adaptations and peculiarities.

Among these, locusts stand out not just for their swarming behavior but for a truly unexpected feature

They have ears on their knees!

Yes, you read that right – knee-ears!

Locusts, belonging to the family Acrididae, are a type of grasshopper that undergoes a remarkable transformation under certain conditions.

While solitary grasshoppers lead a relatively solitary existence, locusts are known for their ability to form swarms, capable of causing widespread devastation to crops.

This transformation, known as phase polyphenism, is triggered by environmental cues such as crowding and changes in vegetation.

When conditions are favorable, locusts transition from a solitary, relatively harmless form into a gregarious, swarming phase, capable of traveling vast distances.

To understand the phenomenon of knee-ears, let’s take a closer look at the anatomy of these intriguing insects.

Locusts have a well-defined body consisting of three segments: the head, thorax, and abdomen.
