Mortality was recorded for (A) Canton S (CS) and (B) eya2 males transferred from darkness (DD) to blue light (BL) at progressively older age indicated in the graph legend. Graphs on the left show mortality curves starting from the day when flies were transferred from DD to BL. Graphs on the right show median survival in BL added to days in DD with survival of flies raised in DD shown as reference. Stars indicate significant differences in survival in BL based on statistics by log-rank test (****p < 0.0001). (C) Lifespan of flies kept in DD or exposed to BL for 10 days, from 5- to 15-day old (blue bar on the x-axis) or from 30- to 40-day old (red bar on the x-axis). D Lifespan was measured in flies kept in constant blue LED light or constant white LED light with blue wavelengths blocked by a yellow filter (LL-BL). Statistics for mortality curves by log-rank test (***p < 0.001 ****p < 0.0001).
