Butterflies are one of the most active insects that do not remain stable and keep moving here and there. Hence it becomes difficult for a person to observe butterflies at one place for more than few seconds. One is forced to chase them continuously to observe their behavior. Butterfly net is a useful tool to catch butterflies and observe them for the required time without doing harm to them. The butterfly net consists of a metallic or wooden handle with removable or fixed rugged metallic ring or wire hoop. An elongated mesh bag (usually made of nylon) is attached to the ring in a manner that its broad mouth is fixed to the ring/hoop and the elongated part ends in a narrowing closed distal end. To catch the butterfly the net is swung in the air such that the flying butterfly is caught in the mesh bag without causing any harm to its body.
One can easily catch butterflies with the help of butterfly net and can keep them in the terrarium for some time where they get basic requirements fulfilled such as air, water, food and security. After their unhandled observation and examination butterflies can be released into the area from where they were collected
