English abstract This study was carried in the Parque Municipal das Araucárias in the municipality of Guarapuava, state of Paraná, Southern Brazil. Three hundred and sixty five nests of T. lactitarse were obtained using trap-nests of 0.7, 1.0, and 1.3 cm in diameter. All of them had similar architecture, regardless of the diameter of the trap-nest. Completed nests consisted of a linear series of brood cells whose average number per nest was of 3.3, 4.0 and 3.6 for the nests with 0.7 cm, 1.0 cm and 1.3 cm in diameter, respectively. They were constructed more often during the summer. T. lactitarse had two types of life cycles: direct development (without diapause), and delayed development (with diapause during winter). Natural enemies included Chrysididae, Sarcophagidae, Dolichopodidae and Ichneumonidae. Out of 1,353 identified spider prey, 1,313 belonged to the Araneidae family
Portuguese abstract Esse estudo foi realizado no Parque Municipal das Araucárias, no Município de Guarapuava (PR), Sul do Brasil. Trezentos e sessenta e cinco ninhos de T. lactitarse foram obtidos utilizando-se ninhos armadilhas de 0,7, 1,0 e 1,3 cm de diâmetro. Todos apresentaram arquitetura similar, independente de seus diâmetros, sendo formados por uma série linear de células, cujo número médio foi de 3,3, 4,0 e 3,6 para os ninhos com 0,7, 1,0 e 1,3 cm de diâmetro, respectivamente. Os ninhos ocorreram com maior frequência no verão. T. lactitarse teve dois tipos de ciclo: um direto sem diapausa, e outro mais longo com entrada em diapausa. Seus inimigos naturais foram: Chrysididae, Sarcophagidae, Dolichopodidae e Ichneumonidae. Das 1.353 aranhas identificadas, 1.313 foram da família Araneidae
