About Paper:

The functionality of eyes in small flying animals is constrained by their physical dimensions. Developing and maintaining large eyes requires a high energy investment and adds weight, limiting flight efficiency but allowing high sensitivity and spatial resolution. Eye scaling strategies relative to body size vary across insects and are expected to match species-specific ecological challenges. Among mosquitoes, variation in the number and size of ommatidia has been recognized among a few species, but little is known about eye-to-body size scaling patterns in connection with ecological roles in mosquitoes. In this study, we hypothesize that ecological function determines the scaling of eye structure in mosquitoes varying between species and sexes. To test this hypothesis, we investigated the allometric scaling of compound eyes across eight mosquito species that differ in their natural history. Given that mosquitoes often have salient sexual differences in foraging behavior, we also examined the scaling pattern of the eyes of males and females for each species. We use light microscopy and photography to quantify eye size and characterize the structure of the eyes. This research contributes to broadening our understanding of the visual adaptations of mosquito eyes, emphasizing how body size influences the structure of compound eyes in insects.
