Hatching intervals of two eggs kept in contact with one another (top panel), separated by ~5 mm (middle panel) with or without a screen,or connected by a piece of wire (bottom panel) at 30°C under continuous illumination in the six indicated grasshopper species (A–F.). Different letters indicate significant differences in mean values at the 5% level by the Steel-Dwass test. Diagrams in panels show how the eggs were arranged in wells.
