Toward a better understanding of host use and biodiversity in riodinid butterflies (Lepidoptera)

Abstract

Over one hundred-eighty observations on the host use and ant association of ninety-eight riodinid butterflies are presented -a substantial addition to our understanding of this distinctly neotropical group. These observations are contrasted to previous work, and discussed with respect to apparent patterns of ph5rtophagy, aph3d;ophagy, caterpillar sociality, and ant association. The majority of riodinid species have unknown life histories, and thus we conclude that much more fieldwork is need before a phylogenetic approach to host use and ant association can be established.
