What is a distinguishing feature of a bed bug?

A distinguishing feature of a bed bug is its flattened body. This characteristic allows bed bugs to hide easily in cracks and crevices, which is crucial for their survival. Their flattened shape enables them to squeeze into tight spaces, making them adept at finding shelter in the seams of mattresses, furniture, and other areas where they may be undisturbed.

In contrast, bed bugs do not have long legs, which would make them less effective at remaining hidden. They also lack wings, as they are an entirely wingless species, contradicting the idea of a winged body. Additionally, their coloration is generally not bright; they are often a reddish-brown, which helps them blend into their environment rather than stand out. Thus, the flattened body is a key identifier for recognizing bed bugs and understanding their behavior.
