Exposure to light enhances pre-adult fitness in two dark-dwelling sympatric species of ants

“…For example, in the intestinal fluke of waterfowls Echinostoma caproni , it has been observed that eggs kept in darkness for up to 56 days do not hatch unless they are exposed to light [ 17 ], and frequency of egg-hatching increases with increasing light intensity [ 18 ]. In the maple aphid Periphyllus californiensis , eggs hatch much faster under shady sites than under sunny sites, because buds which the aphids feed upon open earlier in shady areas than sunny areas [ 19 ]. In the long-horned grasshopper Metrioptera hime , eggs hatch at higher rate under 12:12 hr LD compared to LL or DD [ 20 ].…”
