Water mites are known to live in aquatic habitats and larval or post-larval stages are temporarily or habitually parasitic on the body surface of aquatic animals in their life cycle. Associations on the species level have been documented for 25 species, 14 genera, and 11 families in Hydrachnidiae with 44 species, 36 genera, 24 families, and six orders in Arthropoda and seven species, four genera, two families, and two orders in Mollusca. Host-parasite correspondences between mite and host taxa were observed. A large number of water-mite genera containing Hydrodroma, Hydryphantes, Protzia, Thyas, Lebertia, Sperchon, Hygrobates, Atractides, Piona, Pionopsis, Neumania, Arrenurus, and Stygomomonia were parasitic on dipteran insects. Protzia and Stygomomonia were also parasitic on trichopteran hosts, and Hydryphantes, Eylais, and Hydrachna were parasitic on coleopteran hosts. Aquatic hemipterans were infested with Hydrachna and Lebertia. Lebertia, Piona, and Arrenurus also lived on odonates. On the other hand, plecopterans were exclusively infested with Wandesia, Partnunia, and Stygothrombium. Unionicola was uniquely parasitic on freshwater gastropods and bivalves.

大型ゲンゴロウ類の仲間の多くは絶滅の危機に瀕している。ゲンゴロウとクロゲンゴロウの個体数は減少しているが、それらの近縁種のコガタノゲンゴロウ(コガタノ)は増加傾向にある。諸形質について種間で比較したところ、コガタノは他の2種に比べ、①高温下で幼虫の生存率及び成長速度が高まること、②成虫は活発に飛翔すること、③地域間(本州から南西諸島)で遺伝的変異がほとんどないことが判明した。以上の結果から、近年の地球温暖化の影響でコガタノが増加し、成虫は高い移動分散能力を持つことから、過去に減少または絶滅した地域へと再定着していると考えられた。

The giant water bug, subfamily Lethocerinae, which has the largest body size among Belostomatidae, is known to be a vertebrate specialist that preys mainly upon fish and amphibians. Here, I report that a giant water bug, Kirkaldyia (=Lethocerus) deyrolli (Heteroptera: Belostomatidae), was catching hold of a Japanese mamushi, Gloydius blomhoffii, in a pond. This is a first report of Lethocerinae eating a Viperid snake.
