Butterflies and moths. Demonstration interactive key.
This key is designed for exploring the general principles of interactive identification, and for use in training courses and workshops. When evaluating interactive-key apps, it’s important to carry out real identifications (when the answer is unknown), rather than pretending to identify familiar organisms (when the answer is known beforehand). This key is suitable for that purpose. The characters don’t require special knowledge, and the illustrations can be used as ‘specimens’ to be identified. For more information, see Principles of interactive keys.
