Dragonfly Myths • Dragonflies are called snake doctors because they can bring snakes back from the dead • Dragonflies have stingers which some people are severally allergic to • Dragonflies used to sneak into bad children’s bedrooms and sew their lips together Dragonfly facts . A dragonfly’s wings beat a lot slower than a bees . Huge dinosaur dragonflys lived 300 million years ago . Dragonfly’s eyes have around 30,000 lenses in their eves. Though they can’t see detail well, they can see all the way around. After a dragonfly egg hatches, it can live anywhere from 6 months up to 6 years. Most of it’s life is spent in nymph form. Some species of dragonflies migrate Dragonflies species In all countries accept Antarctica, there are dragonflies.

Appendix A: Common and Scientific Names for Fish and Wildlife Species Found in Idaho
APPENDIX A: COMMON AND SCIENTIFIC NAMES FOR FISH AND WILDLIFE SPECIES FOUND IN IDAHO. How to Read the Lists. Within these lists, species are listed phylogenetically by class. In cases where phylogeny is incompletely understood, taxonomic units are arranged alphabetically. Listed below are definitions for interpreting NatureServe conservation status ranks (GRanks and SRanks). These ranks reflect an assessment of the condition of the species rangewide (GRank) and statewide (SRank). Rangewide ranks are assigned by NatureServe and statewide ranks are assigned by the Idaho Conservation Data Center. GX or SX Presumed extinct or extirpated: not located despite intensive searches and virtually no likelihood of rediscovery. GH or SH Possibly extinct or extirpated (historical): historically occurred, but may be rediscovered. Its presence may not have been verified in the past 20–40 years. A species could become SH without such a 20–40 year delay if the only known occurrences in the state were destroyed or if it had been extensively and unsuccessfully looked for. The SH rank is reserved for species for which some effort has been made to relocate occurrences, rather than simply using this status for all elements not known from verified extant occurrences. G1 or S1 Critically imperiled: at high risk because of extreme rarity (often 5 or fewer occurrences), rapidly declining numbers, or other factors that make it particularly vulnerable to rangewide extinction or extirpation. G2 or S2 Imperiled: at risk because of restricted range, few populations (often 20 or fewer), rapidly declining numbers, or other factors that make it vulnerable to rangewide extinction or extirpation. G3 or S3 Vulnerable: at moderate risk because of restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors that make it vulnerable to rangewide extinction or extirpation.

SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

The Dragonflies and Damselflies (Odonata) of Canadian Grasslands
231 Chapter 8 The Dragonfl ies and Damselfl ies (Odonata) of Canadian Grasslands Robert A. Cannings Royal British Columbia Museum, 675 Belleville Street Victoria, British Columbia, V8W 9W2 [email protected] Abstract. The Odonata are energetic aerial predators of other insects; the aquatic larvae are voracious predators of invertebrates and small vertebrates. As of 2010, 5,952 species of the order were described worldwide; 211 species are known from Canada. Grasslands across the country support about 59% of the national fauna. A checklist and systematic overview of 124 species in nine families are presented. Species totals in these families are as follows: Calopterygidae, 2; Lestidae, 7; Coenagrionidae, 31; Aeshnidae, 16; Gomphidae, 15; Cordulegastridae, 1; Macromiidae, 2; Corduliidae, 13; and Libellulidae, 37. The geographical ranges of the species are defi ned and summarized; according to the defi nitions herein, 20 species have boreal ranges, 17 are transition species, 12 are Cordilleran, 1 is Pacifi c coastal, 10 are western, 4 are more or less restricted to the Great Plains, 16 have southern ranges, 38 are considered eastern, and 6 are widespread species. A summary of studies on grassland Odonata and recommendations for inventory and taxonomic research are provided. The geographical scope of the Canadian grassland fauna is described briefl y with respect to lotic and lentic habitats in grasslands of the Cordillera, the Great Plains, and southern Ontario. Résumé. Les odonates sont de féroces prédateurs aériens d’autres insectes ; leurs larves aquatiques sont aussi des prédateurs voraces d’autres invertébrés et petits vertébrés. En 2010, 5 952espèces d’odonates avaient été décrites dans le monde.

The Dragonflies (Insecta: Odonata) of Northern British Columbia: Field Surveys, Collections Development and Public Education
The Dragonflies (Insecta: Odonata) of Northern British Columbia: Field Surveys, Collections Development and Public Education 2000-2005 Somatochlora brevicincta ♂ Robert A. Cannings Royal British Columbia Museum Leah R. Ramsay British Columbia Conservation Data Centre Sydney G. Cannings NatureServe Yukon Claudia R. Copley Royal British Columbia Museum INTRODUCTION As part of the Living Landscapes Project in northern British Columbia (BC), the Royal British Columbia Museum (RBCM) and the Ministry of Environment’s British Columbia Conservation Data Centre (CDC) joined forces, beginning in 2000, to study the dragonflies (Insecta: Odonata) of the region. The study area includes the province north of about 52º N, approximately the latitude of Williams Lake. Within this area, many wetlands such as streams, springs, marshes, peatlands, ponds and lakes are being sampled. Once ecosystem classification is complete, some of these ecosystems might be considered threatened or endangered by the CDC. Sites east of the Rockies and along the Alaska Highway corridor east of Lower Post were sampled in 1997. Northern BC was sampled in several stages. Figure 1 shows the annual survey areas. The first survey, which began in 2000, focused on the Upper Fraser Basin, centred on Prince George: field work covered the regions around the city and those far to the east and south, that is, the western slopes of the Rockies from Tête Jaune Cache north to Pine Pass, the northeastern Chilcotin Plateau (Nazko area) and the northern Cariboo Mountains (Likely, Quesnel Lake). Sporadic collecting also occurred along Highway 20 to the eastern boundary of Tweedsmuir Park. In 2001 the Vanderhoof-Omineca-Williston regions were examined; in 2002 it was the North Tweedsmuir-Babine-Bulkley-Skeena regions and, in 2003, the far Northwest, including the Hwy 37 corridor, Atlin area, Skagway and Haines roads were studied.
