Morphological staging definitions and values from quantitative time-lapse analyses at 30°C (see also Fig. 1).

aAge is given in hours after egg lay for the minimum age from a 4-hour range, as the mean ± standard deviation. Parenthetical values for percent of development are based on a total embryogenesis period of 72 hours.
bAs the complete blastoderm stage was not quantified, we do not provide a definitive staging landmark and hence do not plot this stage in Figure 1H.
cFor GBE, data were pooled from movie recordings 1 and 2. The separate values are shown in Fig. 1H.
dNote that the staging landmark definition corresponds to the “SR” plot point in Figure 1H, whereas the designations SR1–SR4 in Figure 1 micrographs subdivide the subsequent morphological progression of serosal tissue contraction and withdrawal from the embryo.
