Lepidoptera Sphingidae:) of the Caatinga of Northeast Brazil: a Case Study in the State of Rio Grande Do Norte

Prof. Moraes Rego, s/n, Cidade Universitária, 50670-901, Recife, Pernambuco, Brasil. E-mail:[email protected] ABSTRACT: The caatinga, a thorn-shrub succulent savannah, is located in Northeastern Brazil and characterized by a short and irregular rainy season and a severe dry season. Insects are only abundant during the rainy months, displaying a strong seasonal pat- tern. Here we present data from a yearlong Sphingidae survey undertaken in the reserve Estação Ecológica do Seridó, located in the state of Rio Grande do Norte. Hawkmoths were collected once a month during two subsequent new moon nights, between 18.00h and 05.00h, attracted with a 160-watt mercury vapor light. A total of 593 specimens belonging to 20 species and 14 genera were col- lected. Neogene dynaeus, Callionima grisescens, and Hyles euphorbiarum were the most abundant species, together comprising up to 82.2% of the total number of specimens collected. These frequent species are residents of the caatinga of Rio Grande do Norte. The rare Sphingidae in this study, Pseudosphinx tetrio, Isognathus australis, and Cocytius antaeus, are migratory species for the caatinga. -
The Sphingidae (Lepidoptera) of the Philippines

Apollo, Suppl. 17: 17-132 (1998) 17 The Sphingidae (Lepidoptera) of the Philippines Willem H o g e n e s and Colin G. T r e a d a w a y Willem Hogenes, Zoologisch Museum Amsterdam, Afd. Entomologie, Plantage Middenlaan 64, NL-1018 DH Amsterdam, The Netherlands Colin G. T readaway, Entomologie II, Forschungsinstitut Senckenberg, Senckenberganlage 25, D-60325 Frankfurt am Main, Germany Abstract: This publication covers all Sphingidae known from the Philippines at this time in the form of an annotated checklist. (A concise checklist of the species can be found in Table 4, page 120.) Distribution maps are included as well as 18 colour plates covering all but one species. Where no specimens of a particular spe cies from the Philippines were available to us, illustrations are given of specimens from outside the Philippines. In total we have listed 117 species (with 5 additional subspecies where more than one subspecies of a species exists in the Philippines). Four tables are provided: 1) a breakdown of the number of species and endemic species/subspecies for each subfamily, tribe and genus of Philippine Sphingidae; 2) an evaluation of the number of species as well as endemic species/subspecies per island for the nine largest islands of the Philippines plus one small island group for comparison; 3) an evaluation of the Sphingidae endemicity for each of Vane-Wright’s (1990) faunal regions. From these tables it can be readily deduced that the highest species counts can be encountered on the islands of Palawan (73 species), Luzon (72), Mindanao, Leyte and Negros (62 each). -

About the Book the Format Acknowledgments
About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization. -

ABSTRACT—The application of synchrotron radiation X-ray tomographic microscopy (SRXTM) to the study of mesofossils of Cretaceous age has created new possibilities for the three-dimensional visualization and analysis of the external and internal structure of critical plant fossil material. SRXTM provides cellular and subcellular resolution of comparable or higher quality to that obtained from permineralized material using thin sections or the peel technique. SRXTM also has the advantage of being non-destructive and results in the rapid acquisition of large quantities of data in digital form. SRXTM thus refocuses the effort of the investigator from physical preparation to the digital post-processing of X-ray tomographic data, which allows great flexibility in the reconstruction, visualization, and analysis of the internal and external structure of fossil material in multiple planes and in two or three dimensions. -
Lepidoptera: Sphingidae
Crepuscular and nocturnal hawkmoths (Lepidoptera: Sphingidae) from a fragment of Atlantic rainforest in the state of São Paulo, southeastern Brazil Kely Cristina Rocha Vieira1, Simeão de Souza Moraes2, Pedro Ivo Chiquetto-Machado2 and Marcelo Duarte2,3* Abstract A survey of the richness, abundance and species composition of Sphingidae (Lepidoptera) was performed in a fragment of Atlantic Rainforest at the Serra do Japi Biological Reserve, Municipality of Jundiaí, state of São Paulo, Brazil. Sampling was done monthly, on 2 consecutive nights, from Dec 2011 to Oct 2012, totaling 264 hours of sampling effort. The hawkmoths were attracted by a light trap. Our results were compared with data from a survey of Sphingidae carried out in another fragment of Atlantic Rainforest, i.e., at the Boraceia Biological Station, Municipality of Salesópolis, São Paulo. Richness estimators, rarefaction curves and rank/abundance plots were used to describe the assemblage sampled in this study and to com- pare it with the data set from Boraceia. We collected 462 specimens, members of 3 subfamilies, 5 tribes, 18 genera and 39 species. Callionima parce (Fabricius) was the most abundant species, comprising 33% of the individuals. Orecta lycidas (Boisduval), an under-sampled species in the Atlantic Rainforest, was recorded for the first time in the area of Serra do Japi. The assemblage showed lower species richness and evenness than the assem- blage at Boraceia, probably due to differences in climate, vegetation and size of the forest fragment in which the reserves are situated. Nevertheless, our results emphasize the importance of the Serra do Japi Biological Reserve for the fauna of Lepidoptera of the Brazilian Atlantic Rainforest. -
