| The seasonal characteristics of the Cerrado region strongly influence food resource predictability and vegetal tissue nutritional content. The aims of this work were to record the abundance and temporal distribution of Gonioterma exquisita Duckworth, 1964 (Lepidoptera, Elachistidae) and its relation with phenological, physical, and chemical traits of the host plant Byrsonima pachyphylla Griseb. (Malpighiaceae). Four nutritional quality parameters were determined for new and mature leaves: gross protein and nitrogen content, dry matter, and in vitro digestibility. We inspected 200 plants per month, searching for G. exquisita caterpillars. About 35.8% of the 2,400 plants inspected presented caterpillars, with an abundance peak in the wet season. Caterpillar... |

| In the present work the natural history and immature stages of Gonioterma exquisita Duckworth, 1964 of the Brazilian cerrado region are described. The caterpillars are external folivorous feeders and present a diet restricted to pubescent-leaved host plants of the genus Byrsonima Rich. (Malpighiaceae). They are solitary caterpillars and they build a hard individual shelter that looks like a planorbid shell, made from silk and frass, covered with trichomes and silk, where they develop until the last larval instar on the host plant, and remain inside it until the adult emergence on herbaceous stratum. The larval development presented eight instars. Egg, larval head capsules, instar duration, pupa, shelter, and behavior are also described. Diapause is... |
