Inventory of the caterpillars, their food plants and parasitoids began in 1978 for today's Area de Conservacion Guanacaste (ACG), northwestern Costa Rica. This complex mosaic 120 000 ha conserved regenerating dry, cloud rain forest over 0-2000 m elevation contains at least 10 species non-leaf-mining caterpillars used by more than 5000 parasitoids. Several hundred thousand specimens ACG-reared adult Lepidoptera have been intensively extensively studied morphologically many taxonomists,...

Two species of hairstreak butterflies from the genus Calycopis are known in United States: C. cecrops and isobeon . Analysis mitochondrial COI barcodes revealed -like specimens eastern US with atypical that were 2.6% different either USA species, but similar to Central American species. To address possibility represent an undescribed cryptic we sequenced complete genomes 27 four species: , quintana bactra Some these collected up 60 years ago preserved dry museum collections, nonetheless...

Abstract Comparison of complete genomes closely related species enables research on speciation and how phenotype is determined by genotype. Lepidoptera, an insect order 150,000 with diverse phenotypes, well-suited for such comparative genomics studies if new genomes, which cover additional Lepidoptera families are acquired. We report a 729 Mbp genome assembly the Calycopis cecrops , first from family Lycaenidae largest available genome. As detritivore, shows expansion in detoxification...

Details of egg, larval, and pupal morphology are described illustrated for Calycopis caulonia (Hewitson). In particular, larval chaetotaxy is documented the first time in Calycopis. Lab methods inducing wild-caught females to lay eggs rearing larvae on artificial diet reported. These may be useful several ways resolving basic taxonomy Evidence concerning detritivory myrmecophily C. discussed.

Description and phylogenetic analysis of the Calycopidina (Lepidoptera, Lycaenidae, Theclinae, Eumaeini): a subtribe detritivores. The purpose this paper is to establish basis for new Eumaeini that includes those lycaenid genera in which detritivory has been recorded. Morphological characters were coded 82 species previously proposed "Lamprospilus Section" (19 these had coding identical another species), was performed using 63 distinct ingroup terminal taxa six outgroups belonging four...

Abstract Aim Insects feeding on seeds and fruits represent interesting study systems, potentially able to lower the fitness of their host plants. In addition true seed eaters, a suite insects feed fleshy parts fruits. We examined likelihood community convergence in whole insect assemblages attacking seeds/fruits three tropical rain forests.

Although the butterflies of North America have received considerable taxonomic attention, overlooked species and instances hybridization continue to be revealed. The present study assembles a DNA barcode reference library for this fauna identify groups whose patterns sequence variation suggest need further study. Based on 14,626 records from 814 species, barcodes were obtained 96% fauna. maximum intraspecific distance averaged 1/4 minimum nearest neighbor, producing gap in 76% species. Most...

Abstract We present the first dated molecular phylogeny of Cerurinae moths (Notodontidae), based on sequence data for 666 loci generated by anchored hybrid enrichment. Monophyly is corroborated, which includes following genera: Pararethona Janse, Pseudorethona Oreocerura Kiriakoff, stat. rev., Cerurella Notocerura Hampsonita Afrocerura Cerurina Neoharpyia Daniel, Furcula Lamarck, Neocerura Matsumura, Americerura St Laurent and Goldstein, gen. nov., Cerura Schrank, Kamalia Koçak & Kemal....

From 1992-1998, a study of up to six radio-collared packs free-ranging African wild dogs ( Lycaon pictus ) was conducted in Hwange National Park, Zimbabwe. Wild were primarily observed during the day and data collected across seasons on vocalizations social context. An analysis spectral properties, along with an examination context function, is presented. A vocal repertoire consisting 11 classes 18 subclasses identified.

We describe a new species of extinct riodinid butterfly, Voltinia dramba, from Oligo-Miocene Dominican amber (15-25 Myr ago). This appears to be the first butterfly taxonomically described amber, and adult fossil. The series five specimens represents probably best-preserved fossil record for any lepidopteran. phenomenon extant females ovipositing on arboreal epiphytes explains discovery multiple female V. dramba in amber. one many Hispaniola. northwestern Mexican distribution explicitly...

Larvae of Arawacus lincoides (Lycaenidae) reared in the lab with ants took 0.68 d longer to complete development than larvae without ants. Pupal weight was independent whether a larva had been ant-tended. A delay reaching age first reproduction represents an estimated 1.0%-2.2% lowered intrinsic rate increase for this continuously brooded species. I show that mutualism will be favored when then ratio larval survival is greater exp (dr), where additional time caused by feeding and r increase....

We propose a higher classification of the lycaenid hairstreak tribe Eumaeini - one youngest and most species-rich butterfly tribes based on autosome, Lepidopteran Z sex chromosome, mitochondrial protein-coding genes. The subtribe Neolycaenina Korb is synonym Callophryidina Tutt, Tmolusina Bálint Strephonotina K. Johnson, Austin, Le Crom, & Salazar.

Details of egg, larval, and pupal morphology are described illustrated for Calycopis bellera (Hewitson) C. janeirica (Felder), with a special emphasis on larval chaetotaxy. Wild-caught females laid eggs dead leaves in the laboratory, caterpillars successfully completed development an artificial agar diet to which no were added. Males sexually dimorphic had been previously placed different genera or species groups. chronically misidentified (and misspelled jeneirica). this appear be correctly...

Male secondary sexual characters in Lepidoptera may be present or absent species that otherwise appear to closely related, an observation has led differences of opinion over the taxonomic usefulness these structures above level. An evolutionary issue raised by this debate is whether male (1) can regained after being lost evolutionarily, (2) are not evolved, (3) ‘switched on and off’ genes regulate development. A second conditions under which might gained evolutionarily. Because thought...
