Resumen:
We examined egg sac characteristics and oviposition sites ofMetepeira calamuchita (Piel, 2001) (Araneidae) at two differenthabitat types, creosote bush scrub and Prosopis spp. forestpatches, at the Ñacuñan Biosphere Reserve located in the MonteDesert of Mendoza, Argentina. At each site, we manually collectedegg sacs of M. calamuchita between November and April.We recorded egg sac location, presence of detritus on the egg sacand its colouration. At scrub sites, there was a greater number ofegg sacs anchored to the vegetation, while in forest sites mostegg sacs were suspended by web threads. In addition, more eggsacs covered with detritus were found at scrub sites, but we didnot find an association between egg sac colouration (brown/darkbrown) and habitat type. Location of the egg sac and presence ofdetritus could function as defense strategies in environmentswith different pressures of egg sac predators and parasitoids.
