In Nov. there were not as many odonates as previous months, but still quite a lot of obs added to the proj. The accumulated obs of the Proj exceeded 3,000 this month, and also logged 120 sp & ssp. I think this number 120 sp & ssp covered most of odonates in Taiwan.

According to the report (Yeh, 2009), there were close to 80 species sighted in Nov. then reduced to about 60+ in Dec. So, quite many species are expected to be sighted in Dec as well. If the weather is fine, pls also go out to take some photos of odonates.

Hong @doggy0406 has been topping the boards of both obs and species; in fact, Hong has not only been championing in our Proj but also the top contributor in terms of species and obs in Taiwan.

Sin Syue Li @cleanylee is the toppest mover in our most-species board. Li contributed many rare species which are the very first observations on iNat. With 51 species, Li is currently taking the position of 2nd runner-up. In his 63 obs of odonates, there are 51 sp. He is the most efficient (sp./obs) contributor of the Proj. Thanks to his years of observations and accumulation.
