Sperm storage duration in the grasshopper Eyprepocnemis plorans Charpentier (Orthoptera, Acrididae) was found to be 58.5 days but with a wide between‐female variation (from 26 to 113 days). One copulation was enough to fertilize two to eight egg‐pods and to produce 130 eggs (28–313) and 119 embryos (28–290), on average. Sperm availability, however, decreased progressively with time, so that the majority of females spent a long final period of their lives without laying any pod. Finally, sperm storage duration was positively correlated with clutch size and total production of eggs and embryos.
