Belostoma flumineum
''Belostoma flumineum'' is a North American species of giant water bug (family Belostomatidae). Due to the relatively large size, in length, they are a commonly seen predator in ponds and wetlands. As typical of members of the family, they exhibits exclusive post copulatory paternal care.〔Gilg, M.R., Kruse, K.C. (2003). Reproduction Decreases Life Span in the Giant Waterbug (''Belostoma flumineum''). The American Midland Naturalist, 149, 306-319.〕 Exclusive paternal care has been the focus of many studies done on this species. Other studies have been done on food webs and predation pressure using this species because they are an apex predator (among invertebrates) in their preferred habitats.
== Morphology ==
Ovoid-elongate in body shape that is dorsoventrally flattened and brown in coloration. They can range in length.〔Arnett, R.H. (2000). American Insects: A Handbook of the Insects of America North of Mexico. CRC press, 2, 284.〕 ''B.flumineum'' are insects so naturally have six legs although the front two are strong raptorial legs for catching and holding prey in a vice grip.〔O’Toole, C. (2009). Belostomatinae. In The New Encyclopedia of Insects and their Allies. Oxford University Press Print, 3,??-??.〕 The other four legs are slightly flattened and used for swimming. The mouth parts consist of a stout syringe-like rostrum or beak and long piercing stylets that were once mandibles and maxillae.〔 They also have retractable strap-like appendages that allow for snorkeling while under water which are located on the posterier end of the abdomen.〔 They have large eyes, but lack oceli, which are small light-detecting sensory organs.〔
