The Mitochondrial Genomes of Palaeopteran Insects and Insights
www.nature.com/scientificreports OPEN The mitochondrial genomes of palaeopteran insects and insights into the early insect relationships Nan Song1*, Xinxin Li1, Xinming Yin1, Xinghao Li1, Jian Yin2 & Pengliang Pan2 Phylogenetic relationships of basal insects remain a matter of discussion. In particular, the relationships among Ephemeroptera, Odonata and Neoptera are the focus of debate. In this study, we used a next-generation sequencing approach to reconstruct new mitochondrial genomes (mitogenomes) from 18 species of basal insects, including six representatives of Ephemeroptera and 11 of Odonata, plus one species belonging to Zygentoma. We then compared the structures of the newly sequenced mitogenomes. A tRNA gene cluster of IMQM was found in three ephemeropteran species, which may serve as a potential synapomorphy for the family Heptageniidae. Combined with published insect mitogenome sequences, we constructed a data matrix with all 37 mitochondrial genes of 85 taxa, which had a sampling concentrating on the palaeopteran lineages. Phylogenetic analyses were performed based on various data coding schemes, using maximum likelihood and Bayesian inferences under diferent models of sequence evolution. Our results generally recovered Zygentoma as a monophyletic group, which formed a sister group to Pterygota. This confrmed the relatively primitive position of Zygentoma to Ephemeroptera, Odonata and Neoptera. Analyses using site-heterogeneous CAT-GTR model strongly supported the Palaeoptera clade, with the monophyletic Ephemeroptera being sister to the monophyletic Odonata. In addition, a sister group relationship between Palaeoptera and Neoptera was supported by the current mitogenomic data. Te acquisition of wings and of ability of fight contribute to the success of insects in the planet. -

This formation records a gigantic eolian sand sea (erg), formed under an arid climate in the south-central part of Gondwana. This trackway is composed of two track rows, whose internal width is less than one-quarter of the external width, with alternating to staggered series, consisting of three elliptical tracks that can vary from slightly elongated to tapered or circular. The trackways were found in yellowish/reddish sandstone in a quarry in the Araraquara municipality, São Paulo State. Comparisons with neoichnological studies and morphological inferences indicate that the producer of Paleohelcura araraquarensis isp. nov. was most likely a pterygote insect, and so could have fulfilled one of the Submitted 6 November 2019 ecological roles that different species of this group are capable of performing in dune Accepted 10 March 2020 deserts. -
Fossil Record of Stem Groups Employed In
www.nature.com/scientificreports OPEN Fossil record of stem groups employed in evaluating the chronogram of insects (Arthropoda: Received: 07 April 2016 Accepted: 16 November 2016 Hexapoda) Published: 13 December 2016 Yan-hui Wang1,2,*, Michael S. Engel3,*, José A. Rafael4,*, Hao-yang Wu2, Dávid Rédei2, Qiang Xie2, Gang Wang1, Xiao-guang Liu1 & Wen-jun Bu2 Insecta s. str. (=Ectognatha), comprise the largest and most diversified group of living organisms, accounting for roughly half of the biodiversity on Earth. Understanding insect relationships and the specific time intervals for their episodes of radiation and extinction are critical to any comprehensive perspective on evolutionary events. Although some deeper nodes have been resolved congruently, the complete evolution of insects has remained obscure due to the lack of direct fossil evidence. Besides, various evolutionary phases of insects and the corresponding driving forces of diversification remain to be recognized. In this study, a comprehensive sample of all insect orders was used to reconstruct their phylogenetic relationships and estimate deep divergences. The phylogenetic relationships of insect orders were congruently recovered by Bayesian inference and maximum likelihood analyses. A complete timescale of divergences based on an uncorrelated log-normal relaxed clock model was established among all lineages of winged insects. The inferred timescale for various nodes are congruent with major historical events including the increase of atmospheric oxygen in the Late Silurian and earliest Devonian, the radiation of vascular plants in the Devonian, and with the available fossil record of the stem groups to various insect lineages in the Devonian and Carboniferous. Over half of all described living species are insects, and they dominate all terrestrial ecosystems1. -

Wisconsin Bee Identification Guide
WisconsinWisconsin BeeBee IdentificationIdentification GuideGuide Developed by Patrick Liesch, Christy Stewart, and Christine Wen Honey Bee (Apis mellifera) The honey bee is perhaps our best-known pollinator. Honey bees are not native to North America and were brought over with early settlers. Honey bees are mid-sized bees (~ ½ inch long) and have brownish bodies with bands of pale hairs on the abdomen. Honey bees are unique with their social behavior, living together year-round as a colony consisting of thousands of individuals. Honey bees forage on a wide variety of plants and their colonies can be useful in agricultural settings for their pollination services. Honey bees are our only bee that produces honey, which they use as a food source for the colony during the winter months. In many cases, the honey bees you encounter may be from a local beekeeper’s hive. Occasionally, wild honey bee colonies can become established in cavities in hollow trees and similar settings. Photo by Christy Stewart Bumble bees (Bombus sp.) Bumble bees are some of our most recognizable bees. They are amongst our largest bees and can be close to 1 inch long, although many species are between ½ inch and ¾ inch long. There are ~20 species of bumble bees in Wisconsin and most have a robust, fuzzy appearance. Bumble bees tend to be very hairy and have black bodies with patches of yellow or orange depending on the species. Bumble bees are a type of social bee Bombus rufocinctus and live in small colonies consisting of dozens to a few hundred workers. Photo by Christy Stewart Their nests tend to be constructed in preexisting underground cavities, such as former chipmunk or rabbit burrows. -
New Insects from the Earliest Permian of Carrizo Arroyo (New Mexico, USA) Bridging the Gap Between the Carboniferous and Permian Entomofaunas

Carrizoneura carpenteri gen. et sp. nov. (Syntonopteridae) demonstrates traits in hindwing venation to Lithoneura and Syntonoptera, both known from the Moscovian of Illinois. Carrizoneura represents the latest unambiguous record of Syntonopteridae. Martynovia insignis represents the earliest evidence of Mar- tynoviidae. Carrizodiaphanoptera permiana gen. et sp. nov. extends range of Diaphanopteridae previously restricted to Gzhelian. The re-examination of the type speciesDiaphanoptera munieri reveals basally coa- lesced vein MA with stem of R and RP resulting in family diagnosis emendation. Arroyohymen splendens gen. et sp. nov. (Protohymenidae) displays features in venation similar to taxa known from early and late Permian from the USA and Russia. A new palaeodictyopteran wing attributable to Carrizopteryx cf. arroyo (Calvertiellidae) provides data on fore wing venation previously unknown. Thus, all these new discoveries show close relationship between late Pennsylvanian and early Permian entomofaunas. Keywords Ephemeropterida; Diaphanopterodea; Megasecoptera; Palaeodictyoptera; gen. et sp. nov; early Asselian; wing venation Introduction The fossil record of insects from continental deposits near the Carboniferous-Permian boundary is important for correlating insect evolution with changes in climate and in plant ecosystems. -

Published online at www.senckenberg.de/arthropod-systematics on 30.viii.2017. Editors in charge: Christian Schmidt & Klaus-Dieter Klass Abstract The female cephalothorax of Xenos vesparum (Strepsiptera, Xenidae) is described and documented in detail. The female is enclosed by exuvia of the secondary and tertiary larval stages and forms a functional unit with them. Only the cephalothorax is protruding from the host’s abdomen. The cephalothorax comprises the head and thorax, and the anterior half of the first abdominal segment. Adult females and the exuvia of the secondary larva display mandibles, vestigial antennae, a labral field, and a mouth opening. Vestiges of maxillae are also recognizable on the exuvia but almost completely reduced in the adult female. A birth opening is located between the head and prosternum of the exuvia of the secondary larva. A pair of spiracles is present in the posterolateral region of the cephalothorax. -

Phylum Arthropod Silvia Rondon, and Mary Corp, OSU Extension Entomologist and Agronomist, respectively Hermiston Research and Extension Center, Hermiston, Oregon Member of the Phyllum Arthropoda can be found in the seas, in fresh water, on land, or even flying freely; a group with amazing differences of structure, and so abundant that all the other animals taken together are less than 1/6 as many as the arthropods. Well-known members of this group are the Kingdom lobsters, crayfish and crabs; scorpions, spiders, mites, ticks, Phylum Phylum Phylum Class the centipedes and millipedes; and last, but not least, the Order most abundant of all, the insects. Family Genus The Phylum Arthropods consist of the following Species classes: arachnids, chilopods, diplopods, crustaceans and hexapods (insects). All arthropods possess: • Exoskeleton. A hard protective covering around the outside of the body (divided by sutures into plates called sclerites). An insect's exoskeleton (integument) serves as a protective covering over the body, but also as a surface for muscle attachment, a water-tight barrier against desiccation, and a sensory interface with the environment. It is a multi-layered structure with four functional regions: epicuticle (top layer), procuticle, epidermis, and basement membrane. • Segmented body • Jointed limbs and jointed mouthparts that allow extensive specialization • Bilateral symmetry, whereby a central line can divide the body Insect molting or removing its into two identical halves, left and right exoesqueleton • Ventral nerve -

Is Ellipura Monophyletic? a Combined Analysis of Basal Hexapod
