Halobates sericeus
Pacific pelagic water strider, Silvery Sea Skater
Halobates sericeus is an oceanic sea skater in the family Gerridae, one of the few insects adapted to life on the open sea. It inhabits pelagic marine environments across the Pacific Ocean and adjacent regions. The species exhibits photoperiod-dependent aggregation behavior, with adults and late-instar larvae forming more frequent and longer-lasting groups under short-day conditions compared to long-day conditions.
