Abstract

In many species, males invest both in weapons used in competitions for access to mates and testes size to increase competitive chances for fertilizations. The expression of weapons and testes can be sensitive to environmental factors experienced during development. However, relatively few studies have examined the effects of discrete, natural developmental environments on the expression of these traits in wild populations. In the present study, we examined the development of these primary and secondary sexual traits for the Heliconia bug, Leptoscelis tricolor (Hemiptera: Coreidae) across two different natural host plants, Heliconia mariae and Heliconia platystachys. Development on H. platystachys resulted in increased investment in weapons and reduced investment in testes, whereas development on H. mariae resulted in the opposite pattern. © 2015 The Linnean Society of London, Biological Journal of the Linnean Society, 2015, ●●, ●●–●●.
