According to sperm competition theory, sexually selected weapons compete for resources with other reproductive traits, such as the testes. Because these traits trade-off, males cannot optimally invest in both traits, and thus may maximize weapons or testes, but not both. Leaf-footed bugs (Hemiptera: Coreoidea) have been extensively researched to understand the trade-offs between their hind legs weapons and testes. However, previously published studies on reproductive trade-offs in the Coreoidea have only investigated species with these exaggerated hind legs that function as weapons, but not all species of Coreoidea use their hind legs as weapons. Thus, it is unclear if the documented trade-off is due to the roles of these traits in reproduction, because they contain costly tissues, or for another reason. We selected a Coreoidea species that does not use its hind legs as weapons, Jadera haematoloma (Rhopalidae). We determined whether males of this species reallocates resources to their testes when a hind leg is lost. We induced leg loss in young J. haematoloma and we later weighed each reproductive adult’s testes mass. These results will contribute to our fundamental understanding of resource allocation, sexual selection, and evolution of mating systems.
