Description Insekta memiliki biodiversitas dengan  penyebaran yang luas diseluruh dunia. Sampling dilakukan sekali dalam seminggu selama bulan Oktober 2019. Ditemukan total  717 spesimen Ordo Diptera yang melingkupi dua famili di Sungai Cigambreng. Tiap famili yang diperoleh melingkupi satu jenis yakni Antocha sp. (Famili Tipulidae.) dan Krenopelopia sp. (Chironomidae). Kehadiran jenis chironomid mengindikasikan adanya beban masukan berlebihan (Polutan) ke dalam perairan sungai Cigambreng. Secara umum, kelimpahan tertinggi diperoleh pada pengamatan ke empat yakni 284 ind/m2, sedangkan kelimpahan terendah diperoleh pada pengamatan ke dua yakni 60 ind/m2. Produktivitas sekunder melingkupi P/B Rasio sebesar 3.034/bulan dengan kecepatan produksi 14.2458 (g/m2/bln) dan biomassa (4.6954 g/m2).
Insekta has biodiversity with a wide distribution throughout the world. Sampling was carried out once a week during October 2019. A total of 717 specimens of  Order Diptera were found which covered two families in the Cigambreng River. Each family obtained includes one type, Antocha sp. (Family Tipulidae.) and Krenopelopia sp. (Chironomidae). The presence of a chironomid has indicates an excessive input load (pollutant) into the waters of the Cigambreng River. In general, the highest abundance was obtained at the fourth observation, 284 ind/m2, while the lowest abundance was obtained at the second observation, which was 60 ind/m2. Secondary productivity covers P/B ratio of 3.034 /month with a production speed of 14.2458 (g/m2/month) and biomass (4.6954 g/m2).
