Abstract

The species composition and altitudinal distribution of aquatic insects were investigated from the Southern Hai Van area, Da Nang city. Five sites (75 m, 150 m, 200 m, 300 m and 400 m above sea level) from upper to lower reaches of the stream were sampled from February 2017 to March 2018. The results showed a total of 43 species of 29 genera and 13 families. The Ephemeroptera (Mayflies) was the most diversified with 25 species (58.14% of total species), 15 genera (51.72% of total genera), 4 families (30.77% of total families). The second was the Trichoptera (Cadisflies) with 10 species (23.26%), 8 genera (27.59%), and 5 families (38.46%); followed by Plecoptera (Stonflies) with 8 species (18.60%), 6 genera (20.69%), 4 families (30.77%). The number of collected species decreases with deceased altitudes: 29 at 400 m; 30 at 300 m; 21 at 100 m; 16 at 75 m.
