There is one group that can contribute and that is the macro invertebrates because they can provide us with dragonfly nymphs and info about them if needed and any outside contributors would be helpful and they could do so by using Inaturalist a free app that allows people to upload all types of creatures that are common, uncommon, known, and unknown, but replication could be done anywhere and by anyone as long as they have the appropriate tools and the right weather.Each location has its own consistent rate of dragonflies each time we visit them for example the Lily pool, even if it is not the perfect weather there is always a good portion of dragonflies flying around getting preyed on or hunting for prey themselves.
