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...

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 eac...

We report here the immature stages and natural host plants for three species in the so-called "Taygetis clade" of the nymphalid butterfly subtribe Euptychiina, Taygetis echo (Cramer, 1775), Taygetis sosis Hopffer, 1874, and Pseudodebis valentina (Cramer, 1779). The study was carried out at Finca Las Piedras in Madre de Dios department, Peru. Tayget...

We describe here for the first time the complete immature life cycles and shelter structures of two Neotropical skipper butterflies in the subtribe Moncina, Troyus phyllides (Röber, 1925) and Thoon ponka Evans 1955, along with new natural host plant records for these species at Finca Las Piedras, Madre de Dios, Peru. Four eggs and a preantepenultim...

Here, we describe and name a new nymphalid butterfly species in the subtribe Euptychiina. Caeruleuptychia thaliana Nakahara & Piovesan, n. sp. is proposed by incorporating three independent sources of evidence: adult external morphology, DNA sequence data, and early stage biology. Caeruleuptychia thaliana n. sp. is known from two sites in the Amaz...

The immature stages of two euptychiine butterflies (Nymphalidae: Satyrinae), Paryphthimoides terrestris (Butler, 1867) and Magneuptychia iris (C. Felder & R. Felder, 1867), are described herein and their natural host plants are documented. Notes on the immature stages of these two species were included previously in an unpublished dissertation, alt...

We here document the immature stages of three euptychiine butterflies, Nhambikuara mima (Butler, 1867), Splendeuptychia furina (Hewitson, 1862), and Paryphthimoides brixius (Godart, [1824]), all found feeding on a species of herbaceous bamboo, Taquara micrantha (Kunth) I.L.C.Oliveira & R.P.Oliveira (Poaceae: Bambusoideae: Olyreae) in Madre de Dios,...

We here establish a new genus in the nymphalid butterfly subtribe Euptychiina, Cisandina Nakahara & Espeland, n. gen. to harbor five species hitherto placed within two polyphyletic genera, namely Magneuptychia Forster, 1964 and Euptychoides Forster, 1964. We compiled data from over 350 specimens in 17 public and private collections, as well as DNA...

Here we document the complete life cycle of the Neotropical nymphalid butterfly Taygetis cleopatra (C. Felder & R. Felder, 1862) based on two individuals collected and reared in Madre de Dios, Peru, including the morphology and duration of each life stage. We also report this species' natural hostplant at the study site, a species of herbaceous bam...

We report for the first time the complete immature stages of the Neotropical riodinid butterfly Leucochimona hyphea (Cramer, 1776), based on individuals reared in Madre de Dios, Peru. We illustrate all five larval instars, in addition to the pupa and the egg, and provide the duration of each stage. We also provide evidence for the presence of ant o...

We here report for the first time the complete immature life cycle of a Neotropical skipper butterfly, Ebusus ebusus ebusus (Cramer, 1780), with a report of a new natural hostplant based on a single individual reared at Finca Las Piedras (Madre de Dios, Peru). An egg obtained in nature passed through four larval instars and reached the adult stage,...

We here describe the immature stages of a rare Neotropical satyrine butterfly, Chloreuptychia marica (Weymer, 1911), with a report of its natural hostplant based on two individuals reared in southwestern Amazonia (Madre de Dios, Peru). Two eggs obtained in nature passed through four larval instars and reached the adult stage, and the hostplant was...

We here report for the first time the complete immature life cycle of a Neotropical skipper butterfly, Ebusus ebusus ebusus (Cramer, 1780), with a report of a new natural hostplant based on a single individual reared at Finca Las Piedras (Madre de Dios, Peru). An egg obtained in nature passed through four larval instars and reached the adult stage,...

We here report for the first time the complete life history of Magneuptychia harpyia (C. Felder & R. felder, 1867) (Satyrinae: Euptychiina), based on an individual from Madre de Dios, Peru. An egg obtained from a single female was reared on Lasiacis ligulata Hitchcock & Chase (Poaceae: Panicoideae) and the larva passed through five instars. Images...

In the present study, the immature stages of the Neotropical euptychiine butterfly Taygetis rufomarginata Staudinger, 1888 are described and illustrated in detail for the first time, from specimens collected in Madre de Dios department, Peru. The morphology of all four instars, the egg and pupa, are described and the duration of each stage is recor...

The immature stages of the Neotropical nymphalid butterfly Splendeuptychia quadrina (Butler, 1869) are documented herein based on a population found in Madre de Dios, Peru. Larval morphology is illustrated for the first time for the genus. The host plant is a species of bamboo, identified as Rhipidocladum racemiflorum (Steud.) McClure (Poaceae: Bam...

PurposeThe main goal of this study is to provide a thorough environmental sustainability analysis of the construction, traffic, and maintenance of a 45.6-km section of the ‘Manu Road’, an unpaved tropical road that is currently being built in the vicinity of Manu National Park, in the region of Madre de Dios, Peru. Methods Life cycle assessment (LC...

The construction of roads and other large-scale infrastructure projects, and the secondary impacts they precipitate, are among the key drivers of change in tropical forests. The proposed expansion of a road in the buffer zones of Peru's Manu National Park and Amarakaeri Communal Reserve, in the country's Amazon region, threatens biodiversity and in...

Background/Question/Methods A positive relationship between abundance and distribution is widely considered one of the few general rules in ecology. While such a relationship has been documented in a variety of groups, at multiple scales, and across different biogeographic regions, it is not universal. Furthermore, most studies have focused on ver...
