Avicularia purpurea, also called purple tree tarantula, Ecuadorian purple tarantula or Ecuador purple pinktoe, is a species of spider belonging to the family Theraphosidae (tarantulas). This species can be found in very different habitats, but frequently it is present in agricultural areas, especially in the field of grazing cattle. Sometimes it can be found in holes of walls of buildings or in the spaces below the roofs.
Avicularia purpurea is primarily an arboreal spider. This climbing species builds its nests primarily in hollows in the trees, sometimes in the vicinity of epiphytic plants. These spiders eat mostly crickets, cockroaches, meal worms, waxworms and darkling beetles, but they also can catch small rodents. During mating the females become very aggressive towards the males. A few months after mating the female lays up to 120 eggs in a cocoon. Eight weeks later between 50 and 120 nymphs hatch.
