从大到小的平均尺寸的转变，观察到在Triatoma infestans和Rhodnius arteriticus之间的领域和国内（或实验室）的生活条件。这是更明显的女性标本，导致随后减少性别大小二型性。这一特点进行了讨论，从自然到人工栖息地发生的遗传和人口的变化，特别是那些有关人口密度。性大小二型可作为研究锥蝽亚科种对国内生态环境适应性的一个新性状。
A shift from large to small average sizes was observed in Triatoma infestans and Rhodnius domesticus between field and domestic (or laboratory) conditions of life. It was more pronounced in the female specimens, leading to a subsequent reduction of sexual size dimorphism. This feature is discussed in terms of genetic and populational changes occurring from natural to artificial habitats, in particular those related to population densities. Sexual size dimorphism is then recommended as a new character to be used in the study of species of Triatominae adapting to domestic ecotopes.
