The feeding strategy of the tadpoles of the Shaman Fringe-limbed Treefrog (Ecnomiohyla sukia), a canopy frog endemic to Costa Rica, is reported. A tree was climbed to collect three tadpoles at different stages, then the stomach contents were analyzed. Two of the three collected tadpoles had masses of eggs in their intestines. An analysis of stomach contents found evidence for the presence of around 200 eggs in one specimen. Ecnomiohyla sukia tadpoles are confirmed to be oophagous and can survive by feeding on conspecific eggs. We suggest that oophagy may also be present in other species of the genus Ecnomiohyla; they could use this strategy to supplement the limited food resources available in their microhabitats; however, more research is needed to confirm this.

La diversidad de lagartijas en el Neotrópico es notablemente alta, participan en varias interacciones ecológicas y son componentes relevantes de la red alimentaria en muchos de los ambientes donde habitan. Sphaerodactylidae es una familia muy diversa de pequeños gecos diurnos, con seis especies en Costa Rica, incluido el geco de cabeza amarilla Gonatodes albogularis. Las arañas de cuerpo grande, como algunas Trechaleidae, son capaces de depredar lagartijas, como la araña de bromelia Cupiennius coccineus. Esta no construye telas, sino que embosca y captura presas directamente de la superficie de las hojas y otras partes de las plantas que utilizan para enviar y recibir vibraciones. Reportamos el caso de un geco de cabeza amarilla depredado por una araña de bromelia como el primer reporte de esta interacción trófica en el Bosque Húmedo Tropical del norte de Costa Rica.
