We eval- uate i) the seasonal variation of species richness and composition; and ii) the variation in composition of the local butterfly assemblage among three sampling sites and between the dry and rainy seasons. Sampling was carried out monthly between November 2012 and October 2013, using entomological nets. After a total sampling effort of 504 net hours, 311 species were recorded. One of them is endangered in Brazil, and eight are probable new species. Furthermore, two species were new records for the region and eight considered endemic of the Cerrado domain. There was no significant difference in species richness between the dry and the rainy seasons, however the species composition varies significantly among sampling sites. Due to its special, heterogeneous environment, which is home to a rich butterfly fauna, its preservation is important for the conservation of the regional butterfly fauna.

  • Predatory Behavior of Jumping Spiders
    Annual Reviews www.annualreviews.org/aronline Annu Rev. Entomol. 19%. 41:287-308 Copyrighl8 1996 by Annual Reviews Inc. All rights reserved PREDATORY BEHAVIOR OF JUMPING SPIDERS R. R. Jackson and S. D. Pollard Department of Zoology, University of Canterbury, Christchurch, New Zealand KEY WORDS: salticids, salticid eyes, Portia, predatory versatility, aggressive mimicry ABSTRACT Salticids, the largest family of spiders, have unique eyes, acute vision, and elaborate vision-mediated predatory behavior, which is more pronounced than in any other spider group. Diverse predatory strategies have evolved, including araneophagy,aggressive mimicry, myrmicophagy ,and prey-specific preycatch- ing behavior. Salticids are also distinctive for development of behavioral flexi- bility, including conditional predatory strategies, the use of trial-and-error to solve predatory problems, and the undertaking of detours to reach prey. Predatory behavior of araneophagic salticids has undergone local adaptation to local prey, and there is evidence of predator-prey coevolution. Trade-offs between mating and predatory strategies appear to be important in ant-mimicking and araneo- phagic species. INTRODUCTION With over 4000 described species (1 l), jumping spiders (Salticidae) compose by Fordham University on 04/13/13. For personal use only. the largest family of spiders. They are characterized as cursorial, diurnal predators with excellent eyesight. Although spider eyes usually lack the struc- tural complexity required for acute vision, salticids have unique, complex eyes with resolution abilities without known parallels in animals of comparable size Annu. Rev. Entomol. 1996.41:287-308. Downloaded from www.annualreviews.org (98). Salticids are the end-product of an evolutionary process in which a small silk-producing animal with a simple nervous system acquires acute vision, resulting in a diverse array of complex predatory strategies.

Yet, numerous species of Lepidoptera have evolved biology, ecology and biophysics (Beldade and Brakefield, 2002; highly transparent wings, which often possess scales of altered Prum et al., 2006; Gilbert and Singer, 1975). Lepidopteran wings morphology and reduced size, and the presence of membrane are generally covered with rows of flat, partially overlapping surface nanostructures that dramatically reduce reflection.

  • Altered Functional Properties of the Codling Moth Orco Mutagenized in the Intracellular Loop‑3 Yuriy V
    www.nature.com/scientificreports OPEN Altered functional properties of the codling moth Orco mutagenized in the intracellular loop‑3 Yuriy V. Bobkov1, William B. Walker III2 & Alberto Maria Cattaneo1,2* Amino acid substitutions within the conserved polypeptide sequence of the insect olfactory receptor co‑receptor (Orco) have been demonstrated to infuence its pharmacological properties. By sequence analysis and phylogenetic investigation, in the Lepidopteran subgroup Ditrysia we identifed a fxed substitution in the intracellular loop‑3 (ICL‑3) of a conserved histidine to glutamine. By means of HEK293 cells as a heterologous system, we functionally expressed Orco from the Ditrysian model Cydia pomonella (CpomOrco) and compared its functional properties with a site‑directed mutagenized version where this ICL‑3‑glutamine was reverted to histidine (CpomOrcoQ417H). The mutagenized CpomOrcoQ417H displayed decreased responsiveness to VUAA1 and reduced response efcacy to an odorant agonist was observed, when co‑transfected with the respective OR subunit. Evidence of reduced responsiveness and sensitivity to ligands for the mutagenized Orco suggest the fxed glutamine substitution to be optimized for functionality of the cation channel within Ditrysia. In addition, contrary to the wild type, the mutagenized CpomOrcoQ417H preserved characteristics of VUAA‑binding when physiologic conditions turned to acidic. Taken together, our fndings provide further evidence of the importance of ICL‑3 in forming basic functional properties of insect Orco‑ and Orco/OR‑channels, and suggest involvement of ICL‑3 in the potential functional adaptation of Ditrysian Orcos to acidifed extra‑/intracellular environment. Te odorant receptor co-receptor, Orco, is a unique transmembrane protein, expressed in most of the olfac- tory sensory neurons (OSNs) of insect antennae1–3 and is highly conserved in sequence and function across all insects4,5.

Kons Jr. Last Update: June 2001 Abstract A systematic check list of 489 species of Lepidoptera collected in the University of Florida Natural Area Teaching Lab is presented, including 464 species in the superfamilies Drepanoidea, Geometroidea, Mimalonoidea, Bombycoidea, Sphingoidea, and Noctuoidea. Taxa recorded in Psychidae, Yponomeutidae, Sesiidae, Cossidae, Zygaenoidea, and Thyrididae are also included. Moth taxa were collected at ultraviolet lights, bait, introduced Bahiagrass (Paspalum notatum), and by netting specimens. A list of taxa recorded feeding on P. notatum is presented. Introduction The University of Florida Natural Area Teaching Laboratory (NATL) contains 40 acres of natural habitats maintained for scientific research, conservation, and teaching purposes. Habitat types present include hammock, upland pine, disturbed open field, cat tail marsh, and shallow pond. An active management plan has been developed for this area, including prescribed burning to restore the upland pine community and establishment of plots to study succession (http://csssrvr.entnem.ufl.edu/~walker/natl.htm). The site is a popular collecting locality for student and scientific collections. The author has done extensive collecting and field work at NATL, and two previous reports have resulted from this work, including: a biodiversity inventory of the butterflies (Lepidoptera: Hesperioidea & Papilionoidea) of NATL (Kons 1999), and an ecological study of Hermeuptychia hermes (F.) and Megisto cymela (Cram.) in NATL habitats (Kons 1998). Other workers have posted NATL check lists for Ichneumonidae, Sphecidae, Tettigoniidae, and Gryllidae (http://csssrvr.entnem.ufl.edu/~walker/insect.htm).

  • Hunting Prey with Different Escape Potentials— Alternative Predatory Tactics in a Dune Dwelling Salticid
    2007 (2008). The Journal of Arachnology 35:499–508 HUNTING PREY WITH DIFFERENT ESCAPE POTENTIALS— ALTERNATIVE PREDATORY TACTICS IN A DUNE DWELLING SALTICID Maciej Bartos: University of Lodz, Department of Teacher Training and Studies of Biological Diversity, Banacha 1/3, 90-237 Lodz, Poland. E-mail: [email protected] ABSTRACT. Generalist predators hunt a wide range of prey that possess various characteristics affecting the predators’ hunting success (e.g., size, ability to detect the threat and defend against it, potential for escape). Therefore, it can be expected that the predator should flexibly react to different prey characteristics, hunting them in prey-specific ways. For a stalking predator a crucial prey feature is its ability to escape. In this study, the alternative prey-catching tactics of a dune-dwelling salticid Yllenus arenarius Menge 1868 were analyzed. Four naturally eaten prey taxa, two with a high ability to escape (Homoptera, Orthoptera) and two with a low ability to escape (Thysanoptera, larvae of Lepidoptera), were used. Numerous differences found between the tactics indicate that Y. arenarius can not only distinguish between different types of prey, but can also employ specific tactics to catch them. The tactics belong to a conditional strategy and are manifested in alternative: a) direction of approach, b) speed of approach, and c) other prey specific behaviors. Keywords: Predatory behavior, conditional strategy, spider, Araneae, Salticidae, Yllenus There are numerous examples of alternative 1992; Edwards & Jackson 1993, 1994; Bear & phenotypes expressed through animal morphol- Hasson 1997). ogy, life history, and behavior.

  • CHECKLIST of WISCONSIN MOTHS (Superfamilies Mimallonoidea, Drepanoidea, Lasiocampoidea, Bombycoidea, Geometroidea, and Noctuoidea)
    WISCONSIN ENTOMOLOGICAL SOCIETY SPECIAL PUBLICATION No. 6 JUNE 2018 CHECKLIST OF WISCONSIN MOTHS (Superfamilies Mimallonoidea, Drepanoidea, Lasiocampoidea, Bombycoidea, Geometroidea, and Noctuoidea) Leslie A. Ferge,1 George J. Balogh2 and Kyle E. Johnson3 ABSTRACT A total of 1284 species representing the thirteen families comprising the present checklist have been documented in Wisconsin, including 293 species of Geometridae, 252 species of Erebidae and 584 species of Noctuidae. Distributions are summarized using the six major natural divisions of Wisconsin; adult flight periods and statuses within the state are also reported. Examples of Wisconsin’s diverse native habitat types in each of the natural divisions have been systematically inventoried, and species associated with specialized habitats such as peatland, prairie, barrens and dunes are listed. INTRODUCTION This list is an updated version of the Wisconsin moth checklist by Ferge & Balogh (2000). A considerable amount of new information from has been accumulated in the 18 years since that initial publication. Over sixty species have been added, bringing the total to 1284 in the thirteen families comprising this checklist. These families are estimated to comprise approximately one-half of the state’s total moth fauna. Historical records of Wisconsin moths are relatively meager. Checklists including Wisconsin moths were compiled by Hoy (1883), Rauterberg (1900), Fernekes (1906) and Muttkowski (1907). Hoy's list was restricted to Racine County, the others to Milwaukee County. Records from these publications are of historical interest, but unfortunately few verifiable voucher specimens exist. Unverifiable identifications and minimal label data associated with older museum specimens limit the usefulness of this information. Covell (1970) compiled records of 222 Geometridae species, based on his examination of specimens representing at least 30 counties.
