Abstract: We report the first observation of mass oviposition by the ocean-skater
Halobates sobrinus White in the eastern tropical Pacific Ocean. We netted,
in one scoop, 833 insects and a single egg mass with an estimated 70,000 eggs on
a plastic gallon (3.785-liter) milk jug. Evidently anthropogenic debris could
provide potentially important oviposition substrates for Halobates spp. in the
open ocean. Freshly laid eggs incubated at 26-32°C hatched within 8-10 days.
Eggs kept at temperatures below 22°C did not hatch even after 20 days.
