👉 Pinchbug is a term that refers to an insect species of the family Pieridae, commonly known as the pinworms. They are small, round worms with a white or yellowish-brown body and a black head. Their life cycle involves feeding on plant material, which they use to build their burrows in soil or other vegetation. The term "pinchbug" is often used to describe these tiny insects because they are so closely related to the larger family of pinworms
