👉 The butterfly weapon, also known as the "butterfly trap," is a fascinating defensive mechanism used by certain species of insects, particularly those in the family Lycaenidae, commonly known as blues and yellows. When threatened, these insects rapidly extend their hind legs, resembling the wings of a butterfly, to create a deceptive visual illusion. This sudden movement mimics the appearance of a larger, more dangerous predator, such as a bird, luring the attacker away from their vulnerable body. This clever tactic not only distracts potential threats but also provides an opportunity for the insect to escape or defend itself more effectively.
