Egg, larva, and pupa of Gamelia anableps (C. Felder & R. Felder, 1874) are described for the first time and the chaetotaxy of the first instar provided. Eggs and selected structures of larvae and pupae were also investigated by means of scanning electron microscopy. Eggs are laid in clusters, are ellipsoidal and laterally flat. Larvae passed through eight instars in about 78 days. Pupation occurs inside a poorly organized cocoon of yellowish silk. The dark brown pupa is cylindrical in shape with appendages firmly fused together and to the body wall. The chaeotaxy is compared with other Saturniidae species belongining to Hemileucinae, Ceratocampinae, and Saturniinae and the natural history of G. anableps compared with other Saturniidae.

Arsenura and Titaea (Lepidoptera: Saturniidae: Arsenurinae): new records for the Cerrado of Northeast Brazil

et al. 2022

View full text Add to dashboard Cite

The Northeast region occupies 18.27% of the Brazilian territory with phytophysiognomies of the Amazon Forest, Atlantic Forest, Cerrado and Caatinga (exclusive to this region) biomes (Santos et al., 2020). About 46% of the native area of the Cerrado, one of the main biodiversity hotspots in the world, are converted to pasture or agricultural crops (Hofmann et al., 2021). The area protected of the Cerrado is only 2.2%, increasing the risk of species extinction, including those endemics to this biome (Ferro et al., 2010).

O gênero Chlamydastis Meyrick, 1916 (Elachistidae, Stenomatinae) possui 82 espécies descritas da região Neotropical. Chlamydastis smodicopa (Meyrick, 1915) tem local tipo o Estado de Amazonas, Brasil. No cerrado de Brasília, Distrito Federal, as lagartas de C. smodicopa são folívoras externas restritas à planta hospedeira Styrax ferrugineus Nees & Mart. (Styracaceae). De junho de 2000 a junho de 2001, foram vistoriados 243 indivíduos de S. ferrugineus, e encontradas 38 espécies de lagartas de Lepidoptera em 26% das plantas examinadas. C. smodicopa foi a espécie mais comum em S. ferrugineus mas, apesar disso, ocorreu somente em 7% das plantas. As lagartas apresentam no último ínstar cabeça castanho escuro, placa protorácica marron com faixa amarela na sua margem anterior, tegumento cinza com faixas dorsais e subdorsais marron e amarela, e atingem 30 mm de comprimento. Lagartas são solitárias e constróem abrigos ovóides com duas folhas unidas com fios de seda e com as duas extremidades abertas: uma utilizada para alimentação e a outra para deposição de fezes. Um novo abrigo é construído, à medida que as lagartas crescem ou quando as folhas tornam-se senescentes. No último instar a lagarta constrói um casulo no interior do abrigo foliar, onde ocorre o desenvolvimento da pupa que, em condições de laboratório, teve uma média de 18 dias. As lagartas tiveram a maior freqüência de agosto a setembro, no final da estação seca no cerrado.
