%X En lagartijas la coloraci車n corporal es importanteen la comunicaci車n as赤 como en la protecci車n contra los depredadores. Con el uso de una gu赤a Pantone , se analiz車 el cambio estacional en la coloraci車n dorsal y los microh芍bitats de Aspidoscelis costata costata, una lagartija de amplio forrajeo que habita un ambiente (en el Estado de M谷xico, M谷xico) que cambia dr芍sticamente de apariencia entre sequ赤a y lluvias. Se analiz車 la dependencia de la coloraci車n dorsal de acuerdo a la estaci車n, sexo y estadio de desarrollo. Los resultados indican que la lagartija A. costata costata presenta una coloraci車n dorsal similar al sustrato en cada estaci車n: parda en sequ赤a y principalmente verde en lluvias. Este estudio sugiere: 1) Que la variaci車n en coloraci車n dorsal con funciones cr赤pticas, como la registrada en A. costata costata, puede resultar importante en la supervivencia de especies de amplio forrajeo; 2) Que el cambio en la coloraci車n dorsal en A. costata costata es a nivel individual, ya que un individuo presente en ambas estaciones manifiesta una coloraci車n dorsal parda en la estaci車n de sequ赤a y una coloraci車n dorsal verde en la estaci車n de lluvias y 3) Que la coloraci車n dorsal, con funciones cr赤pticas, est芍 subestimada en especies de amplio forrajeo. Seasonal changes in the dorsal coloration in the lizard Aspidoscelis costata costata (Squamata: Teiidae). Color and color patterns in animals are important characteristics that bring protection, by dampening the ability of predators that depend on their sight to detect their preys. In lizards, the dorsal coloration plays a key role in communication of intraspecific signals such as social cues. In this study, we evaluated the seasonal changes in the dorsal coloration of the wide foraging lizard A. costata costata, in Tonatico, State of Mexico, Mexico. The seasonal evaluation included: the rainy season from mid June to mid September (can also include the end of May to early October); and the dry season for the rest of the year. The dorsal coloration of A. costata costata and their microhabitats were evaluated by contrasting the color pattern with an identification guide and the control colors of Pantone , during 11 samplings carried out from February-October 2007. Individual lizard analysis recorded snout-vent length, sex and stage (juveniles and adults). Besides, all animals were marked by toe-clipping, allowing to distinguish dorsal coloration between seasons, sex and stage. A total of 95 lizards were analyzed (53 and 42 for the dry and rainy seasons respectively). We found that the dorsal coloration in A. cost
