Abstract

This study describes the natural history and multitrophic interactions of the highly restricted Andean butterfly species Catasticta truncata (Lathy & Rosenberg, 1912) from the urban and surrounding areas of Loja in southern Ecuador. The immature stages of the butterfly are described and illustrated, and the host plant is identified as Phoradendron nervosum Oliv. (Viscaceae), an aerial-stem hemiparasitic shrub that parasitizes trees of Salix humboldtiana (Willd) (Salicaceae). Multitrophic interactions that this species maintains in the urban ecosystem are described. One interaction includes a predator, Ambastus villosus Stal, 1872 (Reduvidae). In addition, and for the first time for the genus Catasticta Butler, 1870, the presence of an endoparasitoid wasp (Ichneumonidae) and a hyperparasitoid (secondary parasitoid) wasp Pediobius sp. (Eulophidae), both potentially undescribed species, are documented. Flowers from plants in the Asteraceae family are visited by adults of C. truncata.This new information highlights the ecological roles of these butterflies in the green areas within the city of Loja. Finally, due to the highly restricted distribution of this species within Loja's green areas and the striking beauty of adults, along with this butterfly being a component within 4 trophic levels in the urban ecological network, this butterfly could be a flagship for the city of Loja. Local actions that help the conservation of this species should positively affect the organisms that interact with it and positively influence the well-being of the city's inhabitants in general.

Este estudio describe la historia natural e interacciones multitroficas de la especie de mariposa andina altamente restringida Catasticta truncata (Lathy & Rosenberg, 1912), de las áreas urbanas y circundantes de Loja en el sur de Ecuador. Se describen e ilustran los estados inmaduros de la mariposa, y se identifica la planta hospedera como Phoradendron nervosum Oliv. (Viscaceae), un arbusto hemiparásito de tallo aéreo que parasita árboles de Salix humboldtiana (Willd) (Salicaceae). Se describen las interacciones multitroficas que esta especie mantiene en el ecosistema urbano. Una de las interacciones incluye un depredador, Ambastus villosus Stal, 1872 (Reduvidae). Además, y por primera vez para el género Catasticta Butler, 1870, se documenta la presencia de una avispa endoparasitoide (Ichneumonidae), y una avispa hiperparasitoide (parasitoides secundarios) Pediobius sp. (Eulophidae), ambas especies potencialmente no descritas. Los adultos de C. truncata visitan las flores de plantas de la familia Asteraceae. Esta nueva información resalta la importancia ecológica de estas mariposas en las áreas verdes dentro de la ciudad de Loja. Finalmente, debido a su distribución altamente restringida en las áreas verdes de Loja, y la belleza llamativa de los adultos, junto con su papel importante dentro de cuatro niveles tróficos en la red ecológica urbana, esta mariposa podría ser un símbolo de conservación para la ciudad de Loja. En donde las acciones locales que ayuden a su conservación deberían afectar positivamente al resto de los organismos que interactúan con ella, e influirá positivamente en el bienestar de los habitantes de la ciudad en general.
