Photographic recording dragonflies ans damselflies (Odonata) of Cambodia by public over a decade

Photographs of Odonata taken in Cambodia by public and posted to the ‘Natural Cambodia’ group in a social network for the decade 2012-2022 were followed and registered. After exclusion of already published ones, they comprised a bulk of 682 photographic observations of 91 species, with strong biases towards Anisoptera (74%) and the species with coloured wings (34%) and a strong deficiency of lotic Anisoptera such as Gomphidae and Macromiidae (just one observation of each). Lestes concinnus is for the first time reported for Phnom Kulen Plateau and Lestes platystylus, Heliocyha biforata, Orolestes octomaculatus, Aciagrion occidentale, Ceriagrion calamineum, C. chaoi, Anax guttatus, Gynacantha subinterrupta, Agrionoptera insignis, Brachydiplax sobrina, Cratilla lineata calverti, Orthetrum luzonicum, Rhyothemis obsolescens, R. plutonia, R. triangulare, Tramea transmarina euryale, and Trithemis festiva for the lowlands of Siem Reap Province. It is recommendable to post biodiversity photographs to internet platforms specially designed for this purpose, such as iNaturalist.org, rather than to common social networks which miss functions relevant to operation with scientific data. Important taxonomic notes are made on Aciagrion occidentale, Ceriagrion spp. and Epophthalmia vittata/E. frontalis.
