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 of the prey species showed no evidence of affecting the results. Insects were represented by the house fly "Musca domestica". Unlike the Queensland variant of "P. frimbriata", "P. labiata" has no special tactics when hunting other jumping spiders. "P. labiata" does not prey on ants, but is preyed on by the ants "Oecophylla smaragdina" and "Odontomachus" sp. (species uncertain). "P. labiata" will sometimes approach a translucent nest containing another spider, and will usually wait facing the prey for up to several hours. Occasionally "P. labiata" leaps at the prey in the nest, but this is ineffective. Populations from Los Baños
