A butterfly net (sometimes called an aerial insect net) is one of several kinds of nets used to collect insects. The entire bag of the net is generally constructed from a lightweight mesh to minimize damage to delicate butterfly (or other types of insect) wings.

Nigel tried to use a big butterfly net to catch a Meganeura, but it was clumsy and he failed many times. So, he used an 8-foot water pistol filled with detergent to aid him. Eventually, he was able to shoot down a Meganeura with the water gun and catches it with the net.
