The Streaked Bombardier Beetle (Brachinus Sclopeta) Is One of the UK’S Most Threatened Invertebrates with Modern Records Restricted to London’S Brownfields
© Benoit Martha The Streaked bombardier beetle (Brachinus sclopeta) is one of the UK’s most threatened invertebrates with modern records restricted to London’s brownfields. This easily identifiable beetle is 5-7.5mm long and has a metallic blue-green elytra with a distinctive orange-red streak, and a slim orange-red body. Similar to all bombardier species, when threatened it can spray a boiling, chemical mixture of hydroquinones and hydrogen peroxide from the tip of its flexible abdomen to deter predators. Life cycle Habitat Very little is known of their ecology, but adults have been Streaked bombardier in the UK are now exclusively recorded throughout the year in an apparently active state.

Bronson, Commissioner of Agriculture Argentine Ant, Liniepithema humile Mayr (Hymenoptera: Formicidae) David Westervelt, [email protected], Apiary Inspector and Researcher, Florida Department of Agriculture and Consumer Services, Division of Plant Industry Eric T. Jameson, [email protected], Apiary Inspector, Florida Department of Agriculture and Consumer Services, Division of Plant Industry INTRODUCTION: The Argentine ant, Linepithema humile (Mayr) (Hymenoptera: Formicidae), was introduced into Louisiana in 1890 on coffee ships from Brazil. It has since spread to most of the southern United States where it has become a nuisance pest in the urban environment. It can and does disrupt ecosystems by directly displacing other ant species and other insects. Argentine ants utilize a wide variety of food sources that include protein (live or dead insects) and substances rich in sugars such as honeydew secretions from aphids. Foraging worker ants will also search for food indoors. Argentine ants form large colonies that can include numerous nesting sites that can cover a large area. The Argentine ant can be a serious pest of commercial honey bee hives. This ant challenges the front entrance of the bee hive causing the European honey bee (EHB), Apis mellifera Linnaeus, to guard it. The ants then invade the colony in large numbers through the top or other unguarded openings in the hive (Fig. 1), causing the EHB to abscond, abandoning the honey and brood for the ants to take back to their nest. -
How Bombardier Beetles Survive Being Eaten – and Other Amazing Animal Defence Mechanisms
07/02/2018 How bombardier beetles survive being eaten – and other amazing animal defence mechanisms Academic rigour, journalistic flair How bombardier beetles survive being eaten – and other amazing animal defence mechanisms February 7, 2018 12.03am GMT Author Luc Bussiere Lecturer in Biological Sciences, University of Stirling What goes in must come out. Sugiura & Sato, Kobe University, Author provided (No reuse) In Disney’s film version of Pinnochio, the boy-puppet rescues his creator Geppetto by lighting a fire inside Monstro the whale, who has swallowed them both. The fire causes the whale to sneeze, freeing Pinnochio and Geppetto from their gastric prison. Before you dismiss this getaway as incredible fantasy, consider that new research shows that a kind of fire in the belly can actually be an effective strategy for escaping predators in the real world. In fact, the animal kingdom is full of amazing examples of unusual defence mechanisms that help small creatures avoid a nasty fate. In a new paper in Biology Letters, scientists at Kobe University in Japan describe how bombardier beetles can survive being eaten by a toad by releasing a hot chemical spray that makes the hungry amphibian vomit. Bombardier beetles are so-named because, when threatened, they emit a boiling, irritating substance from their backsides with remarkable accuracy, to deter potential predators. They produce the caustic mixture by combining hydrogen peroxide, hydroquinones and chemical catalysts in a specially reinforced chamber at the base of their abdomen, which shields the beetle’s own organs from the resulting explosive reaction.

The Evolution and Phylogeny of Beetles

Charles R. Darwin Abstract Here we review Charles Darwin’s relation to beetles and developments in coleopteran systematics in the last two centuries. Darwin was an enthusiastic beetle collector. He used beetles to illustrate different evolutionary phenomena in his major works, and astonishingly, an entire sub-chapter is dedicated to beetles in “The Descent of Man”. During his voyage on the Beagle, Darwin was impressed by the high diversity of beetles in the tropics and expressed, to his surprise, that the majority of species were small and inconspicuous. Despite his obvious interest in the group he did not get involved in beetle taxonomy and his theoretical work had little immediate impact on beetle classification. The development of taxonomy and classification in the late 19th and earlier 20th centuries was mainly characterised by the exploration of new character systems (e.g., larval features, wing venation). In the mid 20th century Hennig’s new methodology to group lineages by derived characters revolutionised systematics of Coleoptera and other organisms. As envisioned by Darwin and Ernst Haeckel, the new Hennigian approach enabled systematists to establish classifications truly reflecting evolution. -
Phylogeny and Evolution of Myrmecophily in Beetles, Based on Morphological Evidence (Coleoptera: Ptinidae, Scarabaeidae)
Phylogeny and Evolution Of Myrmecophily In Beetles, Based On Morphological Evidence (Coleoptera: Ptinidae, Scarabaeidae) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Glené Mynhardt Graduate Program in Evolution, Ecology and Organismal Biology The Ohio State University 2012 Dissertation Committee: Johannes Klompen, Advisor Marymegan Daly Norman Johnson T. Keith Philips Copyright by Glené Mynhardt 2012 Abstract Ant-associated behavior has evolved rampantly among various groups of Arthropoda, and has arisen in at least 34 families of beetles. Due to the amazing morphological modifications and different kinds of interactions that occur within myrmecophilous (ant-associated) beetles, authors have predicted that myrmecophily has evolved in a step-wise fashion from casual, facultative associations to closely integrated, obligate interactions. In this dissertation, myrmecophily within the Coleoptera is reviewed, and known behaviors, ant-beetle interactions, and associated morphological adaptations are discussed. In order to better understand how myrmecophily has evolved, two groups of beetles are studied in a phylogenetic context. A cladistic analysis of 40 species of the myrmecophilous scarab genus, Cremastocheilu s Knoch is presented. Characters related to a myrmecophilous habit are largely informative, especially those characters related to the glandular trichomes (clusters of setae typically associated with exocrine glands). Two of the five previously recognized subgenera, C. (Myrmecotonus ) and C. (Anatrinodia ) are synonymized with the subgenus C. (Cremastocheilus ). Even though behavioral information is only known for a few species, the resulting phylogeny indicates that monophyletic subgenera are largely associated with the same ant hosts, although specific interactions with ant hosts can vary even in closely-related taxa. -
GENERAL HOUSEHOLD PESTS Ants Are Some of the Most Ubiquitous Insects Found in Community Environments. They Thrive Indoors and O
GENERAL HOUSEHOLD PESTS Ants are some of the most ubiquitous insects found in community environments. They thrive indoors and outdoors, wherever they have access to food and water. Ants outdoors are mostly beneficial, as they act as scavengers and decomposers of organic matter, predators of small insects and seed dispersers of certain plants. However, they can protect and encourage honeydew-producing insects such as mealy bugs, aphids and scales that are feed on landscape or indoor plants, and this often leads to increase in numbers of these pests. A well-known feature of ants is their sociality, which is also found in many of their close relatives within the order Hymenoptera, such as bees and wasps. Ant colonies vary widely with the species, and may consist of less than 100 individuals in small concealed spaces, to millions of individuals in large mounds that cover several square feet in area. Functions within the colony are carried out by specific groups of adult individuals called ‘castes’. Most ant colonies have fertile males called “drones”, one or more fertile females called “queens” and large numbers of sterile, wingless females which function as “workers”. Many ant species exhibit polymorphism, which is the existence of individuals with different appearances (sizes) and functions within the same caste. For example, the worker caste may include “major” and “minor” workers with distinct functions, and “soldiers” that are specially equipped with larger mandibles for defense. Almost all functions in the colony apart from reproduction, such as gathering food, feeding and caring for larvae, defending the colony, building and maintaining nesting areas, are performed by the workers. -

Previous studies have reported infection of honey bee viruses in ants, raising the concern of ants serving as a reservoir host. Most of these studies, however, are restricted to a single, local ant population. We assessed the status (geographical distribution/prevalence/viral replication) and phylogenetic relationships of honey bee viruses in ants across the Asia–Pacific region, using deformed wing virus (DWV) and two widespread invasive ants, Paratrechina longicornis and Anoplolepis gracilipes, as the study system. -
