Butterfly watching

Butterfly watching (also called butterflying) is a hobby concerned with the observation and study of butterflies. It also includes the "catch and release" of butterflies. There are clubs, handbooks, checklists, and festivals devoted to the activity.

The Canada Day and Fourth of July annual butterfly count, a census of species by butterfly watchers throughout North America, is an example of citizen science.

Well-known butterfly-watching areas include Costa Rica, the Amazon Basin, and sub-Saharan Africa.

Projects in Sweden, the United Kingdom, Finland, the Netherlands, North America, and other countries provide a framework for reporting butterfly sightings in an attempt to understand better what factors threaten or favor European butterflies.
