| description | Wigandia urens (Ruiz & Pavón) H.B.K. (Hydrophyllaceae) is a common shrub at the Pedregal de San Angel reserve in Mexico City. This species has a great morphological and chemical variation on leaves and stems. It is possible to recognize two types of leaves on plants of W. urens: smooth leaves with only glandular trichomes and bristly leaves with urticant hairs and glandular trichomes. The presence and density of trichomes vary according to leaf age and environmental heterogeneity. The great variation of plants of W. urens represents a mosaic of resources to herbivores associated to them. In this study, feeding preferences and patterns of establishment of the most common herbivores on plants of W. urens in the Pedregal de San Angel were studied. Field observations and acceptability experiments were performed. In this study, we found 14 species of herbivore insects belonging to five different orders (Diptera, Hemiptera, Homoptera, Lepidoptera and Orthoptera). In general, all the species showed different degrees of specificity and preference for different parts of W. urens in the field. |

(Hydrophyllaceae) es un arbusto común en la Reserva del Pedregal de San Angel, D.F. Esta especie presenta una gran variación morfológica y química en hojas y tallos. Con base en la pubescencia, se pueden reconocer dos tipos de láminas foliares en esta planta: híspidas con tricomas urticantes y glandulares, y lisas con sólo tricomas glandulares. La presencia y densidad de estos tricomas cambian de acuerdo con la edad de las hojas y la heterogeneidad ambiental. Debido a la gran variación que presenta W. urens, se puede considerar que los individuos de esta especie representan un mosaico de recursos para los herbívoros que coexisten con ella. En tal contexto se estudiaron las preferencias alimentarias y de asentamiento de los fitófagos más comunes que viven sobre W. urens en la Reserva del Pedregal de San Angel. Esto se llevó a cabo con observaciones periódicas en el campo y con experimentos de aceptabilidad. Se encontraron 14 especies de insectos herbívoros asociados a W. urens pertenecientes a cinco órdenes (Diptera, Hemiptera, Homoptera, Lepidoptera y Orthoptera). Estos animales presentaron diferentes grados de predilección y de asentamiento sobre W. urens.
