VELVET ANT Class Order Family Genus Species Insecta Hymenoptera Mutillidae Dasymutilla Spp. Range: Warmer Regions of the Southe
VELVET ANT Class Order Family Genus Species Insecta Hymenoptera Mutillidae Dasymutilla spp. Range: Warmer regions of the southern and western United States Habitat: Usually found in pastures and fields and other open, sandy areas Niche: Diurnal mostly, some species nocturnal Diet: Wild: Adults feed on nectar and pollen; larva is a parasite of a particular bee or wasp species Zoo: Nectar, pollen, sugar water Special Adaptations: The males are somewhat larger, are densely covered with hair and have two pairs of wings but the females are wingless. The antennae and legs are black. The females are slightly smaller and have a long, needle-like stinger concealed at the tip of the abdomen. The female invades a nest of wasps or bumblebees and lays eggs in the cells of the host. The velvet ant larvae kill and eat the host bee pupa. Other: The velvet ant is not really an ant, but is a hairy parasitic wasp. They differ from true ants as they have dense, brightly colored hair. Females can inflict a painful sting if handled and make a squeaking noise when captured. Because of the severe sting of the female, these are often called “cowkillers.” The winged males are harmless. RED HARVESTER ANT Class Order Family Genus Species Insecta Hymenoptera Mutillidae Pogonomyrmex barbatus Range: Southwest United States; Kansas and Oklahoma through western Texas into Mexico and southward through New Mexico and Arizona Habitat: Grasslands, open areas Niche: Omnivorous, terrestrial, Diet: Wild: seeds, dead insects Zoo: Special Adaptations: This species has a red colored body with a row of hairs on the underside of the head (psammaphore). -

A Review of Natural Joint Systems and Numerical Investigation of Bio-Inspired GFRP-To-Steel Joints
materials Article A Review of Natural Joint Systems and Numerical Investigation of Bio-Inspired GFRP-to-Steel Joints Evangelos I. Avgoulas and Michael P. F. Sutcliffe * Department of Engineering, University of Cambridge, Trumpington Street, Cambridge CB2 1PZ, UK; [email protected] * Correspondence: [email protected]; Tel.: +44-1223-332-996 Academic Editor: Frank Müller Received: 25 April 2016; Accepted: 1 July 2016; Published: 12 July 2016 Abstract: There are a great variety of joint types used in nature which can inspire engineering joints. In order to design such biomimetic joints, it is at first important to understand how biological joints work. A comprehensive literature review, considering natural joints from a mechanical point of view, was undertaken. This was used to develop a taxonomy based on the different methods/functions that nature successfully uses to attach dissimilar tissues. One of the key methods that nature uses to join dissimilar materials is a transitional zone of stiffness at the insertion site. This method was used to propose bio-inspired solutions with a transitional zone of stiffness at the joint site for several glass fibre reinforced plastic (GFRP) to steel adhesively bonded joint configurations. The transition zone was used to reduce the material stiffness mismatch of the joint parts. A numerical finite element model was used to identify the optimum variation in material stiffness that minimises potential failure of the joint. The best bio-inspired joints showed a 118% increase of joint strength compared to the standard joints. Keywords: natural joints; adhesive joints; biomimetics; bio-inspiration; composites 1. Introduction In recent years, the use of composite materials in automotive and aerospace industries has shown an upward trend due to their good stiffness-to-weight (E/r) and strength-to-weight (s/r) ratios. -
Dispersal and Survivorship in a Population of Geolycosa Turricola
1991 . The Journal of Arachnology 19:49–5 4 DISPERSAL AND SURVIVORSHIP IN A POPULATION O F GEOLYCOSA TURRICOLA (ARANEAE, LYCOSIDAE ) Patricia R. Miller:' Department of Entomology, Mississippi Entomological Museum , Mississippi State University, Mississippi State, Mississippi 39762 US A Gary L. Miller: Department of Biology, The University of Mississippi, University, Mis- sissippi 38677 USA Abstract. A population of the burrowing wolf spider Geolycosa turricola in Mississippi was monitored over a period of 4 years. Weekly censuses of the number of burrows that were active, open but not active, or inactive were taken . The timing of the dispersal o f spiderlings was examined by use of caging experiments . A habitat manipulation experiment was used to assess burrow site preferences . This population reproduced on a 2-year cycle; no young were produced in even years . The results suggest that some dispersing spiderling s construct burrows immediately after leaving their mother's burrow while others overwinte r and build their first burrow during the spring . Two dispersing groups are identified and are shown to have different survivorship properties . The importance of this dispersal strategy in terms of subsocial behavior is discussed .

Archons (Commanders) [NOTICE: They Are NOT Anlien Parasites], and Then, in a Mirror Image of the Great Emanations of the Pleroma, Hundreds of Lesser Angels
A R C H O N S HIDDEN RULERS THROUGH THE AGES A R C H O N S HIDDEN RULERS THROUGH THE AGES WATCH THIS IMPORTANT VIDEO UFOs, Aliens, and the Question of Contact MUST-SEE THE OCCULT REASON FOR PSYCHOPATHY Organic Portals: Aliens and Psychopaths KNOWLEDGE THROUGH GNOSIS Boris Mouravieff - GNOSIS IN THE BEGINNING ...1 The Gnostic core belief was a strong dualism: that the world of matter was deadening and inferior to a remote nonphysical home, to which an interior divine spark in most humans aspired to return after death. This led them to an absorption with the Jewish creation myths in Genesis, which they obsessively reinterpreted to formulate allegorical explanations of how humans ended up trapped in the world of matter. The basic Gnostic story, which varied in details from teacher to teacher, was this: In the beginning there was an unknowable, immaterial, and invisible God, sometimes called the Father of All and sometimes by other names. “He” was neither male nor female, and was composed of an implicitly finite amount of a living nonphysical substance. Surrounding this God was a great empty region called the Pleroma (the fullness). Beyond the Pleroma lay empty space. The God acted to fill the Pleroma through a series of emanations, a squeezing off of small portions of his/its nonphysical energetic divine material. In most accounts there are thirty emanations in fifteen complementary pairs, each getting slightly less of the divine material and therefore being slightly weaker. The emanations are called Aeons (eternities) and are mostly named personifications in Greek of abstract ideas. -

A Sacrificial Millipede Altruistically Protects Its Swarm Using a Drone
www.nature.com/scientificreports OPEN A sacrificial millipede altruistically protects its swarm using a drone blood enzyme, mandelonitrile Received: 05 January 2016 Accepted: 29 April 2016 oxidase Published: 06 June 2016 Yuko Ishida1,2, Yasumasa Kuwahara1,2, Mohammad Dadashipour1,2, Atsutoshi Ina1,2, Takuya Yamaguchi1,2, Masashi Morita1,2, Yayoi Ichiki1,2 & Yasuhisa Asano1,2 Soldiers of some eusocial insects exhibit an altruistic self-destructive defense behavior in emergency situations when attacked by large enemies. The swarm-forming invasive millipede, Chamberlinius hualienensis, which is not classified as eusocial animal, exudes irritant chemicals such as benzoyl cyanide as a defensive secretion. Although it has been thought that this defensive chemical was converted from mandelonitrile, identification of the biocatalyst has remained unidentified for 40 years. Here, we identify the novel blood enzyme, mandelonitrile oxidase (ChuaMOX), which stoichiometrically catalyzes oxygen consumption and synthesis of benzoyl cyanide and hydrogen peroxide from mandelonitrile. Interestingly the enzymatic activity is suppressed at a blood pH of 7, and the enzyme is segregated by membranes of defensive sacs from mandelonitrile which has a pH of 4.6, the optimum pH for ChuaMOX activity. In addition, strong body muscle contractions are necessary for de novo synthesis of benzoyl cyanide. We propose that, to protect its swarm, the sacrificial millipede also applies a self- destructive defense strategy—the endogenous rupturing of the defensive sacs to mix ChuaMOX and mandelonitrile at an optimum pH. Further study of defensive systems in primitive arthropods will pave the way to elucidate the evolution of altruistic defenses in the animal kingdom. Swarm-forming animals have unique defense systems for protection. -
