From: Monitoring butterflies with an unmanned aerial vehicle: current possibilities and future potentials
Libythea celtis captured with Sony NEX-5 camera in the designated study site. Using hand-held camera, it is possible to spot and determine the target species of the butterflies. This particular study used the Nettle-tree butterfly as the test subject, to discover whether or not small UAVs have the potential to become the main method of accurately monitoring butterflies in as many aspects of their life as possible. The collected results will then be analyzed and used in order to provide a starting point for future research and as a method by which UAVs can be developed to fit a bigger and better purpose as data collectors. We discuss strengths and weaknesses of methods used in this research and give our recommendations and conclusions based on the experience, and biological and ecological background knowledge
