Batrachedra nuciferae Hodges is a pest of the coconut palm (Cocos nucifera L.) in Brazil. The larvae devour the pollen reducing the probability of fecundation of the female flowers and therefore the coconut production. The present paper is a contribution to the identification of this species. Characters of the external morphology of egg, first and last larval instars, pupae (<img id="_x0000_i1031" src="../../../../img/revistas/ne/v33n2/feminino.gif" align=absmiddle> and <img id="_x0000_i1032" src="../../../../img/revistas/ne/v33n2/masculin.gif" align=absmiddle>) and adults (<img id="_x0000_i1033" src="../../../../img/revistas/ne/v33n2/feminino.gif" align=absmiddle> and <img id="_x0000_i1034" src="../../../../img/revistas/ne/v33n2/masculin.gif" align=absmiddle>) are described and illustrated.
