Murici Ecological Station an average of . The dominant vegetation is dense rainforest in the Atlantic Forest biome. In the best preserved areas, mostly at the higher elevations, the forest forms a fairly uniform closed canopy up to high that provides shade and retains moisture. Tree species include murici ("Byrsonima sericea"), "Schefflera morototoni", "Parkia pendula", "Tabebuia" species, "Pseudobombax" species, "Bowdichia virgilioides", "Tapirira guianensis", "Handroanthus impetiginosus" and "Protium" species. The understory contains seedlings of trees, palms such as "Euterpe catinga", and many lianas and epiphytes, such as "Araceae", "Orchidaceae" ("dimerandra" species, "Dichaea" species, "Rodriguezia" species, "Cattleya labiata", "Pleurothallis" species, "Epidendrum" species, "Oncidium" species and
Portia labiata specimens. The following table shows the hunting performance of adult females. In addition to "P. labiata", the table shows for comparison the hunting performances of "P. africana", "P. schultzi" and three regional variants of "P. fimbriata". A female "P. labiata" often hangs a capture web from pliant stems and leaves of shrubs and lower branches of trees, rather than from rocks and tree trunks. Males of "Portia" do not build capture webs. A female "P. labiata" more often pursues small jumping spiders and web spiders than larger prey. While it more often catches small jumping spiders than larger ones, it
