Researcher in Illinois working on water striders. Has links to a checklist, showing some recent (?) revisions of genera. Photos of some species and some discusison on ecology.

Halobates - Oceanic Insects
These are the only pelagic (offshore in salt water) insects. Rather an extensive web site--several pages on biology, taxonomy, etc. Looks like North American species should be: 1-Halobates micans, Gulf of Mexico and southeastern Atlantic coast, and offshore. 2-H. sericeus, southern Pacific coast.
