    Immature stages and biology of the Neotropical skipper Artines angelica Medeiros, 2019 (Hesperiidae: Hesperiinae: Hesperiini: Moncina)
    (Instituto Nacional de Pesquisas da Amazonia, 2025)
    In this study, we describe the immature life stages and two natural host plant associations of the neotropical skipper butterfly Artines angelica Medeiros, 2019 (Hesperiidae), in southeastern Peru. This represents the first published information regarding the basic biology of this species, and only the second for the genus Artines, highlighting our general lack of knowledge of this group. Specimens were collected at the Finca Las Piedras research station in Peru’s Madre de Dios department, where immatures were found and reared on two herbaceous bamboo species, Taquara micrantha (Kunth) I.L.C. Oliveira and R.P. Oliveira and Olyra latifolia L. (both Poaceae). The life cycle of the only individual A. artines found and reared from the egg stage spanned 55 days, during which the species went through six larval instars. The life and natural history information we provide may be useful in understanding the species diversity of the skipper subtribe Moncina, which is extremely diverse yet poorly studied to date.

    Immature stages and new host plant records for eight euptychiine butterflies in southeastern Peru (Lepidoptera: Nymphalidae: Satyrinae: Satyrini)
    (Magnolia Press, 2026)
    We here report the immature stages and novel host plant records for six species in the nymphalid subtribe Euptychiina, which are documented based on populations found in the Madre de Dios department, Peru: Caeruleuptychia urania (Butler, 1867), Harjesia blanda (Möschler, 1876), Deltaya ocypete (Butler, 1867), Yphthimoides renata (Stoll, 1780), Cisandina philippa (Butler, 1867), Cisandina castanya Lamas & Nakahara, 2022. We also report new host plant records for two euptychiine species: Magneuptychia libye (Linnaeus, 1767) and Modestia harpyia (C. Felder & R. Felder, 1867). A total of eight euptychiine species are discussed in the present study and the majority of new host plant records for them belong to the family Poaceae except for M. harpyia which was found feeding on seedlings of Euterpe precatoria (Arecaceae). We provide photos of documented immature stages and host plants for species discussed herein, as well as DNA barcode data for selected taxa.

    Immature stages and host plant records for the skipper butterflies Xeniades orchamus (Cramer, 1777), Dubia dubia (Bell, 1932), and Tricrista canta (Evans, 1955) in the Peruvian Amazon (Lepidoptera: Hesperiidae: Hesperiinae: Hesperiini)
    (Magnolia Press, 2025)
    We describe the immature biology of three skipper species in the tribe Hesperiini (Hesperiidae: Hesperiinae), Xeniades orchamus Cramer in the subtribe Hesperiina, and Dubia dubia Bell and Tricrista canta Evans in the subtribe Moncina. All species were recorded feeding on Guadua weberbaueri Pilger (Poaceae: Bambusoideae: Bambuseae). One larva of each species was collected in nature at Finca Las Piedras, a biological research station located in the Amazonian lowlands of Madre de Dios, Peru. Larvae were reared to adulthood in an onsite laboratory using leaves from G. weberbaueri. We present measurements, descriptions, durations, and photographs of recorded larval instars and pupae, illustrations of larval head capsules, and details of the host plant.
