Adelpha lycorias, the pink-banded sister, is a species of butterfly of the family Nymphalidae.

Adelpha lycorias has a wingspan reaching about 50 millimetres (2.0 in). The uppersides of the wings are generally deep brown, with black apex of the anterior wings. The anterior wings are crossed by a broad band of pink or crimson, irregular in its outer margin, commencing on the middle of the costa and ending at the outer margin. The undersides are chocolate colour, while the nervure, the lines between them and the submarginal line are black. The band of the anterior wings is almost white, slightly tinged with crimson.

1-4-1998 IGUAZU, ARGENTINA - RHINOCEROUS BEETLE (Enema pan)

Dynastinae beetles (Coleoptera: Scarabaeidae) are important due to their role in recycling plant material and promoting nutrient turnover. However, some species are phytophagous and can attack crop plants, thus becoming pests. Here, we provide information on the biology and behavior of the rhinoceros beetle Enema pan (F.) (Oryctini), an abundant species in the area of Cerrado-Pantanal ecotone, Aquidauana, Mato Grosso do Sul, Brazil. Adults were collected with a light trap deployed daily from January 2006 to December 2007 in the experimental farm of the Universidade Estadual de Mato Grosso do Sul (Aquidauana campus). Adults were maintained in plastic containers and observations were made daily. Temporal distribution of adults of E. pan occurred in September and October (2006) and from October to December (2007). Flight started at 1930 hours and ended at 2330 hours. Twenty-four eggs (3.28 mm in length by 2.32 mm in width) with a whitish color were ovipositioned directly in to the soil. Adult longevity averaged 22.0 d in the laboratory conditions. Cephalic horn length, body length, and width of E. pan males are greater than those of females. The weight of adults of both sexes was similar. Cephalic horn length of the males of E. pan was positively correlated with his body size. Mating occurred between 0800 and 1030 hours and lasted on average 18.1 min in the laboratory. Several fights among males and other behaviors involving males and females were observed and are reported.

1-4-1998 IGUAZU, ARGENTINA - SWALLOW TAILED MANAKIN (MALE) (Chiroxiphia caudata)

The blue manakin or swallow-tailed manakin (Chiroxiphia caudata) is a small species of bird in the family Pipridae. It is found mainly in the Atlantic Forest of south-eastern Brazil, eastern Paraguay and far north-eastern Argentina. Its typical habitat is wet lowland or montane forest and heavily degraded former forest. Males have a bright blue body, black head wings and tail and a red crown. Females and juveniles are olive-green. At breeding time, males are involved in lekking behaviour when they sing and dance to impress females. This is a common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern"
