This chapter studies the eggs of stoneflies in sandy shores and evaluates the ecological importance of an ovoid egg located in a mountain stream. It explains that most of the eggs of Perloidea have highly developed structures for attachment to the substrate, but that there are ovoid eggs without these attachment structures among some species. Eggs without attachment structures are found mostly in sand at the water edge of currents near the riffle habitats. The chapter investigates the oviposition site, egg-settling sites, and the behavior and timing of female oviposition in the family group Perloidea in order to clarify the ecological significance of the egg shape in Perloidea.
