The other Suborder contains the damselllies. Although damselflies are frequently referred to, mistakenly, as dragonflies, the two groups are easily distinguished (SeeTable). Odonatans are usually diurnal (daytime) predators which rely on eyesight. They feed on other insects which they capture on the wing. Some speciescruise continuously in search of prey or mates. Others spend much of their time at rest, watching for passing victims. After mating many speciescontinue to fly in 'tandem' as the female lays eggs either inserted into aquatic vegetation or dropped freely onto water. We usually associate dragonflies with water. In Australia their lawae always live One of lhe few specieswilh o common nome islhe emperordrogonfly in fresh water, where they are (Hemionoxpopuensis). voracious predators of other A mole Agriocnemis kunjino. aquatic animals.

For example, within one day of the fust storm in nearly a year, I found eight speciesof dragonflies patrolling a creek in the hills behind Karratha. The sheam had flowed for a few hours, leaving a series of pools which lasted no more than ten days. On another occasiory Charlie Nicholson of the Department of Conservation and Environment encountered hundreds of dragonflies of three speciesalong about three kilometres of the N.W. CoastalHighway between Whim Creek and Port Hedland. The insectswere flying back and forth over spinifex growing on flat, dry, red, sandy plains.

Investment Horizons: Western Balkans, a study of foreign direct investment costs and conditions for two industrial sectors in five countries, was conducted by the Multilateral Investment Guarantee Agency (MIGA) of the World Bank Group. The study was designed in conjunction with the ongoing European Investor Outreach Program (EIOP), a MIGA initiative focused on the Western Balkans and funded through a grant from the Austrian Government. MIGA was established in 1988 to promote the flow of private foreign direct investment to developing member countries. MIGA offers political risk insurance coverage to eligible investors for qualified investments in developing member countries. MIGA also offers technical assistance programs to develop and implement effective strategies for attracting and retaining foreign direct investment. This hands-on technical assistance focuses on three primary areas: dissemination of information on investment opportunities and business operating conditions in developing member countries through online services; capacity building of the organizations and institutions involved in the promotion of foreign investment; and investment facilitation activities supporting the efforts of developing countries to identify and attract investment.

  • Megalagrion Nigrohamatum Nigrolineatum (Perkins 1899) Blackline Hawaiian Damselfly Odonata: Zygoptera: Coenagrionidae
    Megalagrion nigrohamatum nigrolineatum (Perkins 1899) Blackline Hawaiian damselfly Odonata: Zygoptera: Coenagrionidae Photo credit Hawaii Biological Survey Profile prepared by Celeste Mazzacano, The Xerces Society for Invertebrate Conservation SUMMARY Megalagrion nigrohamatum nigrolineatum is endemic to the Hawaiian island of Oahu. This subspecies was found historically in the mountain ranges of Koolau and Waianae, and is currently known from 16 stream sites at high altitudes in the Koolau Range. Its limited habitat and small scattered populations may affect long-term stability. The species is susceptible to the effects of habitat loss and introduced species. Research should focus on habitat management and protection, and control of invasive species. CONSERVATION STATUS Rankings: Canada – Species at Risk Act: N/A Canada – provincial status: N/A Mexico: N/A USA – Endangered Species Act: Candidate USA – state status: S2 Imperiled NatureServe: G4T2 Apparently secure; Subspecies imperiled IUCN Red List: VU Vulnerable SPECIES PROFILE DESCRIPTION Megalagrion n. nigrolineatum is in the family Coenagrionidae (pond damsels). Adults are medium-sized, from 35-45 mm (1.4-1.8 in.) in length with a wingspan of 43-50 mm (1.7-2.0 in.). Adults of both sexes can be recognized by the lime green to blue-green coloration on the lower Species Profile: Megalagrion nigrohamatum nigrolineatum 1 half of the face and eyes (Polhemus & Asquith 1996), and the top portion of the eyes is bright red.

Females have a similar pattern but the patch on the thorax may be yellow to light blue, and final segment of the abdomen is dull orange.

  • Ecosystem Services Provided by the Little Things That Run the World
    Chapter 13 Ecosystem Services Provided by the Little Things That Run the World Olga Maria Correia Chitas Ameixa,Chitas Ameixa, António Onofre Soares,Onofre Soares, Amadeu M.V.M. SoaresM.V.M. Soares and andAna AnaI. Lillebø I. Lillebø Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.74847 Abstract Highest extinction risk and consequently biodiversity loss are predicted to occur in inver- tebrates, specifically insects, and these declines are expected to cascade onto ecosystem functioning and human well-being. Although this knowledge is intrinsically present in more traditional communities, in more urban environments, mapping ecosystem ser - vices can be an important tool to raise people’s awareness on the importance of pre - serving insect diversity. After an extensive revision of the available literature, we used a rule-based approach to assess the provisioning, regulating and maintenance, and cul - tural services delivered by insects. We followed the Common International Classification of Ecosystem Services (CICES) and identified several potential indicators that may help underpin the mapping and valuation of the services delivered by insects. From our search, we extracted a total of 73 indicators, divided as 17 Provisional indicators, 27 Regulation and Maintenance indicators, and 29 Cultural indicators. We concluded that insects are providers of services in the three major ‘Sections’ of ecosystem services defined by CICES. Despite the lack of recognition of provisioning and cultural services, the indicators provided may help to raise awareness on the importance of the little things the run the world, in order to preserve traditional and technological uses of insects and their services.

Booklet.qxd 11.07.2003 10:59 AM Page 3 Introduction to Dragonfly and Damselfly Watching By Mark Klym and Mike Quinn Acknowledgement This work would not have been possible without the input of Bob Behrstock, John Abbott and Sid Dunkle who provided technical information on the Order Odonata in Texas. This is not the first book about this order of insects, and the work of Sid Dunkle in Dragonflies Through Binoculars was a great help in assembling and presenting the material. Pat Morton was a great help in reviewing the material and keeping the work on track. Booklet.qxd 11.07.2003 10:59 AM Page 4 INTRODUCTION Background Dragonflies and Damselflies are members of the insect order Odonata, derived from the Greek word odonto meaning tooth. They are insects meaning that they have three body regions — a head, a thorax to which their four wings and six legs are attached and an abdomen. They are characterized by two pairs of net-veined wings and large compound eyes. Their wings are not linked together, allowing each wing to operate independently of the others. Damselflies have narrowly rectangular heads and eyes separated by more than their own width while dragonfly eyes are never separated by more than their own width. Both are preda- tors throughout their lives and valuable in destroying mosquitoes, gnats and other insects though they can become pests near beehives and may take other beneficial insects like butterflies.
