Odonata Central is a great resource for dragonfly information including (as noted on its homepage): "distribution, biogeography, biodiversity, and identification of Odonata (dragonflies and damselflies) world-wide"
We'd encourage all people taking photographs of dragonflies to enter their data in the Odonata Central database. This can help us all understand the distribution and phenology of the various species.
However, the site is also in need of monetary donations. Updates and improvements to the site and database are planned and this requires resources. Thus, John Abbott (the man behind Odonata Central) has added a link on the home page to make secure online donations.
If you haven't done so before, please go and check out the site.
...and please consider making a tax-deductible donation.
