One of the orders of the class Insecta (Insecta) is the order Lepidoptera (Lepidoptera, from Greek—scaly wings). Insects are included within the phylum Arthropoda (Arthropoda), which is the largest of all animal phyla and also includes crustaceans, arachnids, centipedes, millipedes, and others. Lepidoptera include butterflies and moths, nocturnal butterflies, and it is one of the most beautiful, studied, and well-known orders of insects in the animal world. In various cultures, butterflies are a symbol of beauty and freedom ; their graceful flight together with their great colorfulness attract our attention. In fact, "everyone loves butterflies."

In Israel, although it is not rich in butterfly species, one can find butterflies originating from cold Europe, Asia, the deserts of Arabia and the Sahara, and tropical Africa.

This site tries to briefly explain the structure of the butterfly's body, its life cycle, what distinguishes a butterfly from a moth, and about butterflies in Israel. This site presents most of the day butterflies in the butterflies of Israel. In addition, two important moth families are represented on the site: Saturniidae (one species) and Sphingidae.
