Tobago
Tobago () is an island and ward within the Republic of Trinidad and Tobago. It is located northeast of the larger island of Trinidad and about off the northeastern coast of Venezuela. It also lies to the southeast of Grenada. The official bird of Tobago is the cocrico. Etymology Tobago was named ''Belaforme'' by Christopher Columbus "because from a distance it seemed beautiful". The Spanish friar Antonio Vázquez de Espinosa wrote that the Kalina (mainland Caribs) called the island ''Urupina'' because of its resemblance to a big snail, while the Kalinago (Island Caribs) called it ''Aloubaéra'', supposedly because it resembled the ''alloüebéra'', a giant snake which was supposed to live in a cave on the island of Dominica. The earliest known record of the use of the name ''Tabaco'' to refer to the island is a Spanish royal order issued in 1511. That name was inspired by the resemblance of the shape of the island to the fat cigars smoked by the Taíno inhabitant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann August Hagen
Hermann August Hagen (30 May 1817 – 9 November 1893) was a German entomologist who specialised in Neuroptera and Odonata. He had established himself as one of Europe's preeminent entomologists by 1867 when he accepted a position at Harvard University to curate the Museum of Comparative Zoology. In 1870 he became the first entomologist in the United States to hold the formal title, Professor of Entomology. Biography Hagen was born 30 May 1817 in Königsberg, Prussia. He was the son of Anna (Linck) Hagen and Carl Heinrich Hagen. His father was a senior government counselor and a professor of political science at the University of Königsberg and his grandfather, Karl Gottfried Hagen, was a professor of chemistry at the same university.Henshaw (1894) Young Hagen graduated from a gymnasium in 1836 and began to study medicine at the University of Königsberg. His course of studies was greatly influenced by his zoology professor, Martin Heinrich Rathke and together they toured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized by a pair of large, multifaceted compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural colouration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or ...

Libellulidae
The skimmers or perchers and their relatives form the Libellulidae, the largest dragonfly family in the world. It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded (as Silsby does), there remains a family of over 1000 species. With nearly worldwide distribution, these are almost certainly the most often seen of all dragonflies. The genus '' Libellula'' is mostly New World, but also has one of the few endangered odonates from Japan: '' Libellula angelina''. Many of the members of this genus are brightly colored or have banded wings. The related genus '' Plathemis'' includes the whitetails. The genus ''Celithemis'' contains several brightly marked species in the southern United States. Members of the genus '' Sympetrum'' are called darters (or meadowhawks in North America) and are found throughout most of the world, except Australia. Several Southern Hemisphere species in the ...

Erythemis Collocata
''Erythemis collocata'', the western pondhawk, is a dragonfly of the family Libellulidae, native to western Canada, the western United States, and Mexico. Food Resources ''Erythemis collocata'' is known to feed on the western malaria mosquito, ''Anopheles freeborni ''Anopheles freeborni'', commonly known as the western malaria mosquito, is a species of mosquito in the family Culicidae.

This predation primarily occurs at dusk, when ''A. freeborni'' aggregate into swarms in order to mate. Due to the reliance of ''E. collocata'' on visual stimuli to attack its prey, the frequency of attacks decreases as the sky gets darker.
