Numerous creatures jump by using their powerful hind legs to push off the ground and glide through the air – both horizontally and vertically. A particular excellent model to study the fundamental trade-offs with saltatory locomotion are grasshoppers. These herbivorous insects have femoral leg muscle that acts as a hinge and spring. The goal of our research is to investigate the jump distance of grasshoppers in relation to sex and body mass. We investigated how the trade off between increased body mass due to pregnancy affected female grasshoppers’ ability to escape from predators through jumping. Evolutionarily, females often must compromise their own safety for that of their young. In order to understand this question, we measured the jump distance of females, males, and gravid female grasshoppers. To ensure that the grasshoppers repeatedly jumped, we clipped their wings. Afterwards, we weighed and marked them. To assess sex differences, the jumping frequency and jump distance of both male and female grasshoppers were analyzed during a 5-minute trial. We hypothesize that female grasshoppers, especially during gravid periods, will jump less frequently per minute compared to male grasshoppers, due to their larger mass. All in all, we expect to find a greater jump frequency in male grasshoppers over female grasshoppers. Understanding grasshoppers’ locomotory constraints is imperative for understanding the overall behavior of these insects. Going forward, we anticipate gathering more data trials and comparing anatomical differences in femur length, body length, and body mass in both male and female grasshoppers.
