Phase-dependent morphometric traits of the albino strain of Schistocerca gregaria (Orthoptera: Acrididae)

Sugahara et al. (2017) reported that unlike the wild type, the albino strain of Schistocerca gregaria does not show phase-dependent shift in the morphometric ratio of F/C (= length of the hind femur/maximum width of the head [caput]). In contrast, my old, unpublished, observations clearly demonstrate that S. gregaria albinos exhibited considerable phase-dependent shift in the morphometric ratios F/C and E/F (= length of the fore-wing [elytron] divided by length of the hind femur). Considering the report of Sugahara et al. (2017), I decided to publish my old results
