DESCRIPTION:Sexual selection has resulted in some of the most captivating 
 features of animals\, including flashy colors\, bizarre structures\, and c
 omplex pheromones. These features evolve in complex environments\, where c
 onditions change over space and time. However\, only recently has ecologic
 al complexity been embraced by theory and practice in sexual selection. I 
 will discuss findings revealing that seasonal changes in plants lead to ch
 anges in mate choice and male-male competition in the leaf-footed bugs (Fa
 mily: Coreidae). I will next describe allocation tradeoffs between weapons
 \, testes\, and other traits in these species. Finally\, I will use simila
 r perspectives and approaches to examine phenotypic plasticity in mouthpar
 ts\, naturally-selected traits also closely tied to fitness. I will discus
 s how seasonally-changing resources may lead to greater feeding plasticity
  in insects\, predisposing some to become invasive.
