Physiological condition and wing pigmentation expression in a damselfly with seasonal polyphenism

摘要: Secondary sexual traits can be indicators of individual condition that may present seasonal polyphenism as a result the differential costs expression along season. Wing spots in male damselflies Calopterygidae family are secondary associated with intrasexual competition and mate choice. Hetaerina titia Drury is calopterygid damselfly where males show red black wing spots, contrasting other species genus whose only express spot. In study, we evaluate variation male's their allometric patterns. Additionally, measure form proteins, lipids, soluble carbohydrates glycogen early late seasons. Black higher than season more pigmented. Allometry positive for spot Males concentration glycogen, although there no lipid content. The results study suggest that, H. males, pigmentation replaces function to signal condition. Both traits, however, heavily affected by environmental situations (e.g. food availability).
