Spatiotemporal Pattern of Phenology Across Geographic Gradients in Insects
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2017 Spatiotemporal pattern of phenology across geographic gradients in insects Khelifa, Rassim Abstract: Phenology – the timing of recurrent biological events – influences nearly all aspects of ecology and evolution. Phenological shifts have been recorded in a wide range of animals and plants worldwide during the past few decades. Although the phenological responses differ between taxa, they may also vary geographically, especially along gradients such as latitude or elevation. Since changes in phenology have been shown to affect ecology, evolution, human health and the economy, understanding pheno- logical shifts has become a priority. Although phenological shifts have been associated with changes in temperature, there is still little comprehension of the phenology-temperature relationship, particularly the mechanisms influencing its strength and the extent to which it varies geographically. Such ques- tions would ideally be addressed by combining controlled laboratory experiments on thermal response with long-term observational datasets and historical temperature records. Here, I used odonates (drag- onflies and damselflies) and Sepsid scavenger flies to unravel how temperature affects development and phenology at different latitudes and elevations. The main purpose of this thesis is to provide essential knowledge on the factors driving the spatiotemporal phenological dynamics by (1) investigating how phenology changed in time and space across latitude and elevation in northcentral Europe during the past three decades, (2) assessing potential temporal changes in thermal sensitivity of phenology and (3) describing the geographic pattern and usefulness of thermal performance curves in predicting natural responses. -
Monitoring of Odonata in Britain and Possible Insights Into Climate Change

In: Ott J (Ed) (2010) Monitoring Climatic Change With Dragonfl ies. BioRisk 5: 127–139. doi: 10.3897/biorisk.5.846 Abstract Th e history of recording and monitoring of Odonata in Britain is briefl y described. Results are then pre- sented which suggest that the country’s Odonata fauna is currently in a period of fl ux, in a manner consist- ent with the actions of a high-level regulatory factor such as climate change. Th e ranges of many resident species are shifting. Leucorrhinia dubia has recently been lost from southern England, but many species are presently expanding their ranges to the north and west, some (such as Aeshna mixta and Anax imperator) with considerable speed. In addition to these changes, a number of ‘southern’ species have started to ap- pear in Britain for the very fi rst time. Th ese include Lestes barbarus, Erythromma viridulum (which has now become a locally-common resident in southeast England), Anax parthenope and Crocothemis erythraea. -

Subarctic Darner Aeshna Subarctica
Natural Heritage Subarctic Darner & Endangered Species Aeshna subarctica Program State Status: Endangered www.mass.gov/nhesp Federal Status: None Massachusetts Division of Fisheries & Wildlife DESCRIPTION OF ADULT: The Subarctic Darner is a stunning insect species in the order Odonata, suborder Anisoptera (the dragonflies), and family Aeshnidae (the darners). The adult is a large dragonfly magnificently colored with greens, blues, and rich browns. The thorax (winged and legged segment behind the head) is mostly brown, with two green to blue dorsal stripes and two blue-green to yellowish lateral stripes. The abdominal segments are predominantly brown with green to blue markings. The Subarctic Darner has black legs and transparent to amber-tinged wings. The face is yellow with a thin black cross-line, and the eyes are dull blue- gray to green in color. Subarctic Darners range from 2.6 to almost 3 inches (66-76 mm) in overall length, with the females averaging somewhat larger. Wingspread ranges from 3.1 to 3.6 inches (78-92 mm). SIMILAR SPECIES: Ten species of blue darners (genus Aeshna) occur regularly in Massachusetts and the Subarctic Darner closely resembles many of them in appearance. The slight differences in pattern and and can be distinguished from other Aeshna using coloration distinguish the various species. The face of characteristics as per the keys in Walker (1958). the adult Subarctic Darner is yellow with a black cross- line. In addition, the lateral thoracic stripes are bent HABITAT: Sphagnum bogs and deep fens with wet forward in their upper halves, with the top of the stripe sphagnum. -

DRAGONFUES 1 Tj
Family Corduliidae. Medium-sized hawkers with distinctly metallic bodies _ usually bronze or green. Triangles of the two wings differ in shape, that of the forewing having front and basal sides about equal. Claspers usually well DRAGONFUES 1 developed in both sexes. Male abdomen distinctly narrowed in the front half. 85 Downy Emerald Cordulia aenea. Shiny green thorax, densely clothed with golden hair. Abdomen dark bronze with sides of 2nd segment clear yellow in male. Inferior anal appendage of male deeply forked and resembling an extra pair of claspers. Hindwing triangle undivided. Female stouter than male. Flies swiftly over lakes and ponds and rarely settles. 4-8. Most of Europe, but rare in S. 8 Brilliant Emerald Somatochlora metallica. Thorax much less hairy than Cordulia and abdomen much brighter green - detectable even in flight. Claspers much longer than in Cordulia, especially in female. Inferior anal appendage of male unforked. Triangle of hindwing 2-celfed. Female stouter than male and easily identified by a sharp spine under the abdomen just before the tip. Still and slow-moving water in lowlands and mountains. Flies rapidly. 6-9. Most of Europe, but not Iberia. Two distinct populations in B: one in SE England and one in NW Scotland. B n Northern Emerald S.arctica, a similar but more northerly species, has strongly curved claspers in male and no abdominal spine in female. Family Libellulidae. A large family of darters in which triangles are of different shapes in the two wings: that of the forewing has front side very much shorter than basal side.
