1 It's All Geek to Me: Translating Names Of
IT’S ALL GEEK TO ME: TRANSLATING NAMES OF INSECTARIUM ARTHROPODS Prof. J. Phineas Michaelson, O.M.P. U.S. Biological and Geological Survey of the Territories Central Post Office, Denver City, Colorado Territory [or Year 2016 c/o Kallima Consultants, Inc., PO Box 33084, Northglenn, CO 80233-0084] ABSTRACT Kids today! Why don’t they know the basics of Greek and Latin? Either they don’t pay attention in class, or in many cases schools just don’t teach these classic languages of science anymore. For those who are Latin and Greek-challenged, noted (fictional) Victorian entomologist and explorer, Prof. J. Phineas Michaelson, will present English translations of the scientific names that have been given to some of the popular common arthropods available for public exhibits. This paper will explore how species get their names, as well as a brief look at some of the naturalists that named them. INTRODUCTION Our education system just isn’t what it used to be. Classic languages such as Latin and Greek are no longer a part of standard curriculum. Unfortunately, this puts modern students of science at somewhat of a disadvantage compared to our predecessors when it comes to scientific names. In the insectarium world, Latin and Greek names are used for the arthropods that we display, but for most young entomologists, these words are just a challenge to pronounce and lack meaning. Working with arthropods, we all know that Entomology is the study of these animals. Sounding similar but totally different, Etymology is the study of the origin of words, and the history of word meaning. -

Learning from the extraordinary: How the highly derived larval eyes of the Sunburst Diving Beetle can give insights into aspects of holometabolous insect visual systems A dissertation submitted to the Division of Research and Advanced Studies of the University of Cincinnati In partial fulfillment of the requirements for the degree of Doctorate of Philosophy (Ph.D.) In the department of Biological Sciences of the College of Arts and Sciences 2011 by Nadine Stecher B.S., University of Rostock, 2001 M.S., University of Rostock, 2005 Committee Chair: Elke K. Buschbeck, Ph.D. Abstract Stemmata, the eyes of holometabolous insect larvae, vary greatly in number, structure and task. The stemmata of the Sunburst Diving Beetle, Thermonectus marmoratus, are among the most sophisticated. The predatory larvae have six eyes and a potentially light-sensitive spot (eye spot) adjacent to the stemmata. The forward-pointing tubular eyes Eye 1 (E1) and Eye 2 (E2) are involved in prey capture, and possess a biconvex lens, a cellular crystalline cone-like structure, and tiered retinal tissue. A distal and a proximal retina can be distinguished, which differ not only in morphology but possibly also in function. E1 has an additional retina which runs medially alongside the crystalline cone-like structure. Using transmission electron microscopic preparations, I described the ultrastructure of the retinas of the principal eyes E1 and E2. The proximal retinas are composed of photoreceptors with predominantly parallel microvilli, and neighboring rhabdomeres are oriented approximately orthogonally to each another. This rhabdomeric arrangement is typical for eyes that are polarization sensitive. A similar organization is observed in a portion of the medial retina of E1, but not in either of the distal retinas. -

Abstract Light represents one of the most reliable environmental cues in the biological world. In this review we focus on the evolutionary consequences to changes in organismal photic environments, with a specific focus on the class Insecta. Particular emphasis is placed on transitional forms that can be used to track the evolution from (1) diurnal to nocturnal (dim-light) or (2) surface to subterranean (aphotic) environments, as well as (3) the ecological encroachment of anthropomorphic light on nocturnal habitats (artificial light at night). We explore the influence of the light environment in an integrated manner, highlighting the connections between phenotypic adaptations (behaviour, morphology, neurology and endocrinology), molecular genetics and their combined influence on organismal fitness. -
Opsin Duplication and Subfunctionalization for Short-Wavelength Sensitivity in Jewel Beetles (Coleoptera: Buprestidae) Nathan P
Lord et al. BMC Evolutionary Biology (2016) 16:107 DOI 10.1186/s12862-016-0674-4 RESEARCH ARTICLE Open Access A cure for the blues: opsin duplication and subfunctionalization for short-wavelength sensitivity in jewel beetles (Coleoptera: Buprestidae) Nathan P. Lord1*, Rebecca L. Plimpton2, Camilla R. Sharkey1, Anton Suvorov1, Jonathan P. Lelito3, Barry M. Willardson2 and Seth M. Bybee1 Abstract Background: Arthropods have received much attention as a model for studying opsin evolution in invertebrates. Yet, relatively few studies have investigated the diversity of opsin proteins that underlie spectral sensitivity of the visual pigments within the diverse beetles (Insecta: Coleoptera). Previous work has demonstrated that beetles appear to lack the short-wavelength-sensitive (SWS) opsin class that typically confers sensitivity to the “blue” region of the light spectrum. However, this is contrary to established physiological data in a number of Coleoptera. To explore potential adaptations at the molecular level that may compensate for the loss of the SWS opsin, we carried out an exploration of the opsin proteins within a group of beetles (Buprestidae) where short-wave sensitivity has been demonstrated. RNA- seq data were generated to identify opsin proteins from nine taxa comprising six buprestid species (including three male/female pairs) across four subfamilies. Structural analyses of recovered opsins were conducted and compared to opsin sequences in other insects across the main opsin classes—ultraviolet, short-wavelength, and long-wavelength. Results: All nine buprestids were found to express two opsin copies in each of the ultraviolet and long-wavelength classes, contrary to the single copies recovered in all other molecular studies of adult beetle opsin expression. -
Millipedes and Centipedes? Millipedes and Centipedes Are Both Arthropods in the Subphylum Myriapoda Meaning Many Legs
A Teacher’s Resource Guide to Millipedes & Centipedes Compiled by Eric Gordon What are millipedes and centipedes? Millipedes and centipedes are both arthropods in the subphylum Myriapoda meaning many legs. Although related to insects or “bugs”, they are not actually insects, which generally have six legs. How can you tell the difference between millipedes and centipedes? Millipedes have two legs per body segment and are typically have a body shaped like a cylinder or rod. Centipedes have one leg per body segment and their bodies are often flat. Do millipedes really have a thousand legs? No. Millipedes do not have a thousand legs nor do all centipedes have a hundred legs despite their names. Most millipedes have from 40-400 legs with the maximum number of legs reaching 750. No centipede has exactly 100 legs (50 pairs) since centipedes always have an odd number of pairs of legs. Most centipedes have from 30- 50 legs with one order of centipedes (Geophilomorpha) always having much more legs reaching up to 350 legs. Why do millipedes and centipedes have so many legs? Millipedes and centipedes are metameric animals, meaning that their body is divided into segments most of which are completely identical. Metamerization is an important phenomenon in evolution and even humans have a remnant of former metamerization in the repeating spinal discs of our backbone. Insects are thought to have evolved from metameric animals after specializing body segments for specific functions such as the head for sensation and the thorax for locomotion. Millipedes and centipedes may be evolutionary relatives to the ancestor of insects and crustaceans. -
Ordinal-Level Phylogenomics of the Arthropod Class
Ordinal-Level Phylogenomics of the Arthropod Class Diplopoda (Millipedes) Based on an Analysis of 221 Nuclear Protein-Coding Loci Generated Using Next- Generation Sequence Analyses Michael S. Brewer1,2*, Jason E. Bond3 1 Department of Environmental Science, Policy, and Management, University of California Berkeley, Berkeley, California, United States of America, 2 Department of Biology, East Carolina University, Greenville, North Carolina, United States of America, 3 Department of Biological Sciences and Auburn University Museum of Natural History, Auburn University, Auburn, Alabama, United States of America Abstract Background: The ancient and diverse, yet understudied arthropod class Diplopoda, the millipedes, has a muddled taxonomic history. Despite having a cosmopolitan distribution and a number of unique and interesting characteristics, the group has received relatively little attention; interest in millipede systematics is low compared to taxa of comparable diversity. The existing classification of the group comprises 16 orders. Past attempts to reconstruct millipede phylogenies have suffered from a paucity of characters and included too few taxa to confidently resolve relationships and make formal nomenclatural changes. Herein, we reconstruct an ordinal-level phylogeny for the class Diplopoda using the largest character set ever assembled for the group. Methods: Transcriptomic sequences were obtained from exemplar taxa representing much of the diversity of millipede orders using second-generation (i.e., next-generation or high-throughput) sequencing. These data were subject to rigorous orthology selection and phylogenetic dataset optimization and then used to reconstruct phylogenies employing Bayesian inference and maximum likelihood optimality criteria. Ancestral reconstructions of sperm transfer appendage development (gonopods), presence of lateral defense secretion pores (ozopores), and presence of spinnerets were considered. -
