Despite the urban and landscape impact caused by Drymoea veliterna (Druce, 1885) (Lepidoptera: Geometridae) larvae on trees of the genus Croton L. (Euphorbiaceae) in the Neotropics, there is no information about its biology and reproductive traits. In this study, we describe the life cycle and reproductive traits of this species. Its life cycle lasts approximately 56 days, the larvae develop during 24 days on average and the longevity of the females is 7 days on average. Females have an average fecundity of 207 eggs. Regarding their reproductive system, the presence of previtellogenic eggs in the reproductive tract of the females is emphasized. The bursa copulatrix and a highly sclerotized signum is depicted. The number of spermatophores found in the reproductive tract of the females was quantified. Male and female genitalia were schematized.
This study aims to preliminary assess the taxonomic diversity of dragonflies and damselflies from San José del Guaviare, Guaviare Department, Colombia. A total of 47 species were collected at five localities in different freshwater ecosystems during a field trip. We highlight three new species records for the country: Erythrodiplax tenuis Borror, 1942, Micrathyria spinifera Calvert, 1909, and Perithemis rubita Dunkle, 1982. Finally, a new species of Perissoletes is described from Guaviare and Casanare, Colombia.
An updated and comprehensive checklist of wild silkmoths (Lepidoptera: Saturniidae) from Colombia is presented, including their occurrence status in each Colombian department. In Colombia, there are a total of 6 subfamilies, 55 genera, and 602 species of Saturniidae. Current distribution data shows that one genus and 310 species are endemic to Colombia. As a result of the description of many new species for the neotropics, some species names presented in the first checklist of Colombian Saturniidae (Amarillo-Suárez 2000) are obsolete. The following taxa, hitherto treated as subspecies, are raised to species status: Arsenura lemairei Racheli & Racheli, 1998 stat. nov. from A. thomsoni Schaus, 1906; Copiopteryx banghaasi Draudt, 1930 stat. nov. from C. semiramis (Cramer, 1775); and Rhescyntis norax Druce, 1897 stat. nov. from R. hippodamia Druce, 1897. A new combination is proposed in this context: Copiopteryx banghaasi andensis (Lemaire, 1974) comb. nov. In addition, Bathyphlebia aglia gschwandneri Schawerda, 1925 stat. nov. is removed from its synonymy with B. aglia Felder & Felder, 1874 and here treated as a subspecies of the latter. Furthermore, Rothschildia equatorialis bogotana Rothschild, 1907 stat. rev., comb. nov. is reinstated as a subspecies, but now from equatorialis Rothschild, 1907 and not from orizaba (Westwood, 1853). The following taxa are recognized as new synonyms: Rhescyntis hippodamia colombiana (Bouvier, 1927) syn. nov. of Rhescyntis norax Druce, 1897, Therinia transversaria columbiana (Jordan, 1924) syn. nov. of Therinia transversaria (Druce, 1887), and Rothschildia arethusa rhodina Jordan, 1911 syn nov. of Rothschildia arethusa (Walker, 1855). Old records of taxa that recently could not be found in Colombia have been removed due to new evidence. The purpose is to avoid confusion with old names and provide an updated list of Colombian species, including many recently described taxa.
A female of Automeris jucunda (Cramer, 1779) was collected during a field expedition to Otanche, Colombia. The rearing of this species was conducted in captivity, in situ and in the laboratory, on different food plants as the larvae revealed to be polyphagous. In Colombia, the larval phase lasted six weeks on Schizolobium parahyba S. F. Blake, 1919 (Fabaceae), a natural host plant of A. jucunda. Instead, in the laboratory the larval phase lasted more than eight weeks on Rubus fruticosus Linnaeus, 1753 (Rosaceae), a replacement food plant for this species. The gregarious larvae developed between five to six instars and can also cause erucism. The immature stages of A. jucunda are described together with food plants. Furthermore, short taxonomic notes on the A. hamata subgroup, which includes A. jucunda, are provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
