Xylophagids are a small group of dipterans with 133 known species worldwide except for in the Afrotropical region; they are composed of three subfamilies: Coenomyiinae, Rachicerinae and Xylophaginae. Their larvae are predatory and tend to be found under bark, soil or decaying wood. Hitherto, the following five species in three genera of Xylophagida...

... single available female specimen from Korea differs from the Japanese form by several features as follows: the fore basitarsus is pale brown, the base of the hind femur is without a brownish tinge, the base of the hind basitarsus is pale yellow, and all knees (base of the tibia) are paler ( Nagatomi and Saigusa, 1968). Furthermore, the patterns and color of the wing from the Korean specimen resemble those in figure 16 in Nagatomi and Saigusa (1968), whereas the apical margin of the wing is more infuscate and the border of crossvein m-m, R4, R5, and M1-M4 is more clearly tinged with brown. The Korean material also differs from the Russian specimen, e.g., the apex of the coxa and femur are yellowish brown, the fore tibia is pale brown but the base is yellowish, only the base of the mid tibia is pale yellow, the base of both the basitarsus and tarsomere 2 are pale yellow, and the apical margin of the wing is darker brown (Krivosheina and Krivosheina, 2000). ...

Background
True flies (Diptera) are an ecologically important group that play a role in agriculture, public health and ecosystem functioning. As researchers continue to investigate this order, it is beneficial to link the growing occurrence data to biological traits. However, large-scale ecological trait data are not readily available for fly species. While some databases and datasets include fly data, many ecologically relevant traits for taxa of interest are not included. In this study we create a dataset containing ecological traits (habitat and diet) for fly species of Canada and Greenland having occurrence records on the Barcode of Life Data Systems (BOLD). We present a dataset containing trait information for 983 Diptera species.
New Information
Diptera were chosen for the dataset based on the occurrence records available for Diptera species from Canada and Greenland on the Barcode of Life Data Systems (BOLD). Trait data were then compiled based on literature searches conducted from April 2021 - January 2023 and assigned at the lowest taxonomic level possible. Three biological traits were included: habitat, larval diet, and adult diet. The dataset contains traits for 983 species across 380 genera, 25 subfamilies, and 61 families. This dataset allows for assignment of traits to occurrence data for Diptera species and can be used for further research into the ecology, evolution, and conservation of this order.
This study determined population genetic structure measures, compared these measures across species with different biological traits; and created efficient, reproducible, reusable programming modules that are publicly available for future research. Cytochrome C Oxidase subunit I gene sequences from Diptera (true fly) species from Greenland and Canada were used as a case study and proof of concept. We hypothesized that population genetic structure measures will be influenced by the biological traits of organisms. Data were pulled from public databases, as well as taxon-specific literature. The R pipeline includes fifteen modules that can be adapted and applied to a diverse set of animal groups, geographic regions, genes, and traits. Habitat, larval diet, geographical distance, latitude, and longitude were all significantly related to population genetic structure in Diptera. Overall, this study has created efficient, reusable bioinformatics modules, as well as provided insight into the factors affecting population genetic structure in Northern fly communities.
