Data from: Seasonality, body size and maturation time in the neotropical grasshopper Sphenarium histrio across an altitudinal gradient
<p>In insects, male mating success and female fecundity usually increase with body size. However, natural selection favors faster maturation, reducing the risk of pre-reproductive death when the reproductive season is short in habitats located at high altitudes or far from the equator. Also, if males that mature earlier than females under these conditions increase their mating opportunities, protandry may evolve in their populations. Nonetheless, since body size is strongly correlated with maturation time in insects, a faster sexual maturation is reached at the expense of having a small body size. We analyzed the differences in the adult body size of males and females of the grasshopper Sphenarium histrio in three sites across an altitudinal gradient in southern Mexico. We also evaluated the possibility of protandry in these sampling sites using a common garden experiment. Male and female grasshoppers collected from low altitude sites in the field and reared in the laboratory were larger than those from a high altitude, suggesting genetic differentiation. Grasshoppers from a high altitude hatched earlier, had a shorter development time, presented fewer instars, and were smaller than grasshoppers from the other sampling sites. Moreover, development time in the three sampling sites was shorter in males than in females, suggesting protandry. Interestingly, the males from the three sites showed similar growth rates, but the females from low and high altitudes, respectively, had the fastest and slowest growth rates. In general, the adaptive value of the evolution of protandry has been focused on males. However, it may be that the growth rates of females in these sites could modify the degree of protandry as a response to their risk of pre-reproductive death and the potential benefits associated with multiple matings.</p> <p>The xlsx file contains the data for all the statistical analyses.</p>

Interpopulation variation in sexual dichromatism in the neotropical grasshopper Sphenarium purpurascens (Orthoptera: pyrgomorphidae).
<p>Cryptic coloration is an adaptative defensive mechanism against predators. Color patterns can become cryptic through background coloration-matching and disruptive coloration. Disruptive coloration may evolve in visually heterogeneous microhabitats, whereas background matching could be favored in chromatically homogeneous microhabitats. In this work, we used digital photography to explore the potential use of disruptive coloration and background matching in males and females of the neotropical grasshopper <em>Sphenarium purpurascens</em> in different habitats. We found chromatic differences in the three habitats and sexual dichromatism that may be explained by local adaptation. Even though females and males are sexually dichromatic, there are interpopulation differences in the magnitude of the sexual dichromatism. In an environment highly contrasting, but visually homogeneous, both males and females seem to follow mainly a disruptive strategy, whereas in highly contrasting and heterogeneous environments males and females seem to follow different color cryptic strategies, males are more disruptive than females. In contrast, females have a high background matching with less disruptive elements. The predators’ selective pressures in different microhabitats and the differences in mobility between sexes may explain the color pattern divergence between females and males.</p>
