Distribution of flies of medical importance in Thailand

Each record comprises information across three primary categories: (i) Taxonomy – including scientific name, kingdom, phylum, class, order, family, genus, specific epithet, scientific name authorship, and taxon rank; (ii) Collection details – including event ID, occurrence ID, event date, and sampling protocol; (iii) Geolocation data – including county, country code, locality, location ID, decimal latitude, decimal longitude, and geodetic datum.

An overview of the dataset is presented through four summary tables. Table 1 displays the total number of collected fly specimens, organized by family. The most frequently recorded family is Simuliidae, which accounts for 52.16% of all entries.

Table 2 presents the total number of collected flies classified by type—biting or non-biting—and further categorized by family. Biting flies represent the majority, comprising 65.67% of all specimens. Within this group, Simuliidae is the most prevalent family (79.43%), while Calliphoridae is the most dominant among non-biting flies (58.90%).

Table 3 illustrates the geographic distribution of biting and non-biting flies across different regions of Thailand. Notably, the Central region is the only area where non-biting flies outnumber biting flies. Table 4 summarizes the number of specimens collected using different sampling methods, and the manual collection by forceps yields the highest number of specimens overall.
