Riechia acraeoides (Guérin-Méneville, [1832])
( Fig. 9 View FIGURES 2 – 9 )
Castnia acraeoides Guérin-Méneville , [1832]
Taxonomic history. The genus was discerned thanks to its resemblance to certain species in the genus Actinote ( Nymphalidae : Acraeinae) ( Miller 1986). The species was described by Guérin-Méneville in the genus Castnia , and was eventually placed in the genus Herrichia ( Buchecker, [1880]). Since this proposed genus was found to be preoccupied, Oiticica (1955) replaced it for Riechia .
Distribution. Widely distributed in South East Brazil, this species can be also found in Northern Argentina and Paraguay ( Miller 1986; Jörgensen 1930). It resembles some species of Actinote Hübner ( Nymphalidae : Acraeinae) ( Miller 1986; Jörgensen 1930). Jörgensen (1930) cites it from San Bernardino, Cordillera Department, Paraguay.
Biology and behavior. Two males were collected by the first author on two different dates in a disturbed forest in Asunción. Both were resting under an Yvapurú tree, Myrciaria cauliflora (Mart.) O. Berg , Myrtaceae , at midday. Tillandsia sp., a possible hostplant, was observed to be quite common in this forest. The species has been detected flying during the day in December and January in some locations in Brazil ( Biezanko 1961a).
The larvae have been found feeding on Tillandsia meridionalis Baker and T. didisticha (E. Morren) Baker (Bromeliaceae) ( Miller 1986). They have been reared in Argentina under laboratory conditions using pseudobulbs of Miltonia flavescens Lindl. (Orchidaceae) (A. Tricio, pers. comm.). A female was observed ovipositing on Oncidium jonesianum Rchb. f. ( Orchidaceae ) ( Jörgensen 1930). Biezanko (1961a) mentions that the larvae feed on Tillandsia aeranthos (Loisel) L.B. Smith (Bromeliaceae) and a few Orchidaceae ( Cattleya intermedia (Graham) , C. loddigesii Lindl. and Laelia purpurata (Lindl. & Paxton) .
