Methods of odonatological investigations
Observation and photographing
It is possible to identify Odonata fliying in field when you have experince with the group. Odonatologists could observe odonates from the shore or from the boat using binocular.
Since the time when professional phototechnique appeared it becomes possible to make photos of dragonflies instead of preserving specimens in collections. Obtained photos could be send for verification to specialists and used for different purposes: on regional or national Odonata webpages, as illustrations for scientific or scientific-popular articles, etc.
This methods help to protect species from collectors especially this is important for rare and endangered species. Althought in some cases we should also collect specimens to avoid mistakes in identification.
