Specimens of ocean skaters Halobates were collected off the south coast of Japan in the East China Sea in 1995, and from the Kumano‐nada Sea to the East China Sea in 1998 and 1999. Three species were identified: H. micans, H. germanus and H. sericeus. We found two species co‐occurring in comparable densities in different years, a phenomenon not hitherto reported in other regions of the ocean. We discuss distributions of the three Halobates species with special reference to the influence of the… 
Occurrence and density of Halobates micans (Hemiptera: Gerridae) in the eastern South Indian Ocean
From December 1992 to December 1993, Halobates was intensively sampled in the easternmost region of the South Indian Ocean, suggesting that H. micans lives in the study area at high densities comparable to those in the Atlantic and the Pacific Oceans.

Data collected during an oceanographic cruise along the southeastern Brazilian coast in March 1982 showed that the marine insect Halobates micans occurred along the Southeastern Brazilian Bight, but in lower abundance in low-temperature areas due to the intrusion and upwelling of South Atlantic Central Water, and inLow salinity areas in Coastal Water.

Distribution of the pelagic insects Halobates spp. in the western Pacific Ocean
Although insects surpass all other living organisms on the earth in species numbers, they are relatively unsuccessful in the marine realms. Out of one million extant insect species, a few thousands
Skaters of the seas – comparative ecology of nearshore and pelagic Halobates species (Hemiptera: Gerridae), with special reference to Japanese species
An updated distribution map is presented along with global current systems and sea-surface temperatures, interactions between distribution ranges and physical factors at the air–sea interface are examined and spatio-temporal variations in populations of each species are discussed.
Seasonal and decadal changes in distribution patterns of Halobates (Hemiptera: Gerridae) populations in the eastern tropical Pacific
There is substantial overlap in ranges during seasonal shifts, but very little co-occurrence of H. sobrinus and H. micans in individual net tows, suggesting biological mechanisms rather than physical factors are restricting distribution and co-Occurrence of these two species.
Distinct population histories among three unique species of oceanic skaters Halobates Eschscholtz, 1822 (Hemiptera: Heteroptera: Gerridae) in the Eastern Pacific Ocean
Key insights drawn from the results of this study, alongside future resolution of evolutionary relationships among Halobates species, will complete the understanding of how these remarkable insects conquered the high seas where no other insect could.
Genetically separate populations of the ocean‐skater Halobates sericeus (Heteroptera: Gerridae) have been maintained since the late Pleistocene
It is suggested that physical conditions and/or biotic interactions on the surface of the Pacific Ocean have provided significant barriers to gene flow since the late Pleistocene or earlier, creating biotic stability over large geographical and temporal scales in spite of a long history of global climate change.
Molecular phylogeny of sea-skaters (Halobates Eschscholtz, 1822), relationship between Halobatini and Metrocorini, and a catalogue of the subfamily Halobatinae (Hemiptera: Heteroptera: Gerridae)
It is confirmed that the limnic lifestyle of Metrocorini was ancestral in Halobatinae, and the marine lifestyle evolved only once in the common ancestor of Asclepios + Halobates, and that the open ocean was colonized at least three times inHalobates.


Oceanic diffusion and the pelagic insects Halobates spp. (Gerridae: Hemiptera)
Abstract Five pelagic Halobates species occupy a vast area from 40∘ north to 40∘ south in the three major oceans. Oceanic diffusion, constantly acting to disperse these insects, must be an important
Halobates specimens were sorted from 1,649 surface neuston samples collected from the eastern tropical Pacific Ocean. At least one specimen was captured in each of 498 samples. Only 34 samples
Distribution and environmental synchronization of the marine insect, Halobates robustus, in the Galapagos Islands
It was demonstrated that the daily bimodal rhythm of encounters is triggered by dawn and, since it is not maintained in constant light or dark, an ‘hour-glass’ mechanism is suggested.
The Current System in the Yellow and East China Seas
During the 1990s, our knowledge and understanding of the current system in the Yellow and East China Seas have grown significantly due primarily to new technologies for measuring surface currents and
Factors Limiting the Distribution of Halobates Species
The open ocean is almost devoid of insects, except for members of the genus Halobates, first described in 1822, but until the late 1970s marine biologists paid very little attention to these unique insects.

Biology of Halobates (Heteroptera: Gerridae)
Until about 10 years ago Halobates was probably known to only a handful of entomologists; outside this segment of the entomological world it was generally unknown. However, during the last 10 years
