As the name suggests, butterfly watching is simply observing the appearance and behavior of butterflies, which may sometimes involve catching them, studying them, and releasing them back to nature. Although lesser known than birdwatching and wildlife observation, butterfly watching has a dedicated group of enthusiasts around the world with clubs and festivals dedicated to the activity and there are many of those who trot the globe to watch and observe butterflies.
All of the 20,000 (approx.) species of butterflies found in the world fall under the order Lepidoptera along with moths and skippers with whom they share many characteristics. Butterflies are known for their vibrant and colorful exterior although plenty of butterflies sport neutral earthy tones. One such butterfly Dreamy Duskywing (Erynnis icelus) is covered in dirt brown color commonly associated with moths. An adult butterfly can have a lifespan from one week to about a year and their life cycle comprises of four stages: eggs, larva (Caterpillar), Pupa (Chrysalis) and adult (Butterfly)—with the complete metamorphosis taking anywhere from a month to about a year depending on the type of butterfly.
Nepal is a great destination for butterfly watchers with 651 species of butterflies found here, which is about 3.72 percent of the total species of butterflies found in the world. Around 20 of these species are endangered. Because of the variation in both geography and climate with altitude and located where Palearctic and oriental eco-zones meet, both Palearctic species like Parnassius acdestis, common red apollo (Parnassius epaphus), Synchloe sherpae etc. and oriental species like Kaiser-i-Hind (Teinopalpus imperialis), common brimstone (Gonepteryx rhamni), great orange tip (Hebomoia glaucippe), the great eggfly (Hypolimnas bolina), red helen (Papilio helenus), Paris peacock (Papilio paris) etc. are found here.
Nonetheless, 90 percent of the species found here are Oriental species found in the temperate and tropical region as compared to 10 percent of Palearctic species found only in the upper Himalayan region above 3000 meters.
