RESUMO

The goal of this work was to describe aspects of the biology and morphology of Leucanella viridescens (Walker, 1855), a polyphytophagous species that is a pest to several crops of economical interest and whose larvae may cause erucism. Biological parameters were obtained under controlled conditions: temperature of 25 ± 1ºC, relative humidity of 70 ± 10%, and a 14 h photophase. Morphological and behavioral aspects were analyzed in each developmental phase. The larval stage had six instars, with an average growth rate of 1.396. A high degree of polyphytophagy was observed, including over 49 host plant species belonging to 25 families, especially Leguminosae, Solanaceae and Salicaceae. The considerable chromatic variability of the adults obtained from the same egg batch corroborates the need for a new taxonomic assessment of L. viridescens viridescens Walker, 1855 and L. viridescens viridior Lemaire, 1973.
