👉 The term "Piophilinae" is a genus of insects in the family Lepidoptera, commonly known for their long, thin tongues that are used for collecting nectar and pollen from flowers. This group includes the most common species, such as the black widow (Biston mariana), which can be found throughout much of Europe, Asia, and Africa. Their diet consists primarily of nectar, but they also feed on various fruits, seeds, and even small insects.
