Figure 2 from: Tanaka S (2021) Embryo-to-embryo communication facilitates synchronous hatching in grasshoppers. Journal of Orthoptera Research 30(2): 107-115. https://doi.org/10.3897/jor.30.63405

Figure 2 Relationship between number of eggs in a group and mean hatching times in six grasshopper species under continuous illumination and 30°C temperature. For each species, hatching times were normalized by assigning a value of 5 h to the mean hatching time of the largest group. n (number of eggs in each treatment) is given above each histogram. Different letters indicate significant differences in mean values at the 5% level using the Tukey's multiple test (A–E.) or the t- test (F.). ns indicates no significant difference.
