Phylogenetic Ecology of Marine Water Striders
Summary
Marine water striders represent a striking example of insect life at the ocean’s surface, a habitat dominated by pelagic organisms. Central to this group is the genus Halobates, the only insect lineage known to inhabit the open ocean. Phylogenetic ecology integrates evolutionary history with ecological traits to reveal how water striders colonised and diversified across saline interfaces. Molecular phylogenies trace successive adaptations for fluid locomotion, desiccation resistance and salinity tolerance, while ecological studies document habitat preferences, dispersal pathways and life history strategies. Together, these approaches elucidate the global distribution of marine water striders, their resilience to environmental change and their role as indicators of ocean surface processes. Insights from this field also inform broader questions of insect evolution, long-distance dispersal and the limits of terrestrial lineages in marine realms.

Phylogenetic Ecology of Marine Water Striders publication trend
The graph below shows the total number of articles in phylogenetic ecology of marine water striders across all publications each year (not limited to Nature Index journals).
Technical terms
Phylogenetic ecology: Integration of evolutionary relationships with ecological traits to explain species distributions and adaptations.
Gerromorpha: Infraorder of semi-aquatic bugs, including water striders, that inhabit water–air interfaces from ponds to open ocean.
Halobates: The only insect genus that lives on the open ocean surface, exhibiting specialised adaptations to saline and wave-affected environments.
Long-distance dispersal (LDD): Movement of organisms across large geographic distances leading to colonisation of isolated habitats, often via rafting or wind-driven transport.
