This is a serie of scientific papers, published in different news in entomology and natural history. The mayority are investigations about life cycles and ecology, contributing to the systematic and nomenclatural topics.
New altitudinal distribution records are reported for several species. Aditionally, the life cycles of six species from two families were provided: Pieridae: (Pierini: Aporiina): Catasticta semiramis; Nymphalidae: pronophilina: Pedaliodes phaea, P. phaeinea, P. pollusca, P. phoenissa, P. empusa. The association of these species with the host plant was established. Morphologic characcteristis of each one of the preimaging stances and ethology aspects are discussed.
