Spiders of this genus are mainly Brazil and it belongs to the Anolis carolinensis species distributed in Asia, subtropical Africa and Australian group (Rodríguez-Schettino, 1999; Prates et al., 2016). region (World Spider Catalog, 2020). They build The species is well adapted to urbanised and highly specialised non-sticky webs to catch their prey, which anthropised environments where it can be found in street are typically comprised by flying insects that get trapped lampposts, fences, shrubs, trees and lawns (Prates et al., on the dense mesh (Levi, 1997) and can be restrained 2016). Their individuals are mainly insectivores, but by direct biting or immobilisation wrapping (Lubin, occasionally feed on plant material or small vertebrates 1980). A well-marked characteristic of webs built by (Rodríguez-Schettino, 1999). These characteristics Cyrtophora spiders are their strength and endurance, enable this species to be easily introduced in other which would be an adaptation to withstand strong winds areas, including the Baixada Santista region at the and rainfall in open habitats (Lubin, 1973).
