This page represents the following TreeOfLife-200M taxonomic path.[1]
Azelia trigonica is a small fly, consistent with the general size range of the genus Azelia (2.5–5.5 mm).[2] Members of the genus are characterized by dark coloration.[2] The scutum is typically velvety black anteriorly, with the posterior part of the postsutural area appearing brownish-grey dusted.[2] The abdomen is generally dusted, featuring an interrupted median stripe and paired lateral spots on each tergite.[2] Morphological details observed in specimens, such as those in the TreeOfLife-200M dataset, support these general diagnostic features.[1]
Azelia trigonica has a wide distribution, historically considered European, but now known to extend into Asia, including regions such as eastern Kazakhstan and Russia (e.g., Altai Republic, Sakha-Yakutia, Tver, St. Petersburg, and Krasnodar).[2] Southern records include Serbia and the Caucasus, indicating a preference for northern, cooler regions.[2] Flies in the genus Azelia are typically associated with the dung of large herbivores.[2]
