Abstract

The last-instar nymph of Alcmeone robustus (Butler, 1877) (Membracidae, Darninae, Darnini) is described and illustrated, and some biological and behavioral notes are provided. The nymphs were observed on Pera sp. (Euphorbiaceae) in the locality of Jacareí, state of São Paulo, Brazil, until they became adults.
