Firecracker Skimmer
The flame skimmer or firecracker skimmer (''Libellula saturata'') is a common dragonfly of the family Libellulidae, native to western North America. Description Male flame skimmers are known for their entirely red or dark orange body, this includes eyes, legs, and even wing veins. Females are usually a medium or darker brown with some thin, yellow markings. This particular type of skimmer varies in size but is generally measured somewhere between long. The naiads are known for being rather large and chubby-looking due to their rounded abdomen. They are covered with hair but, unlike most young dragonflies, they lack hooks or spines.

Philip Reese Uhler
Philip Reese Uhler (June 3, 1835 – October 21, 1913) was an American librarian and entomologist who specialized in Hemiptera, an insect order commonly known as true bugs. He was considered America's foremost expert on this group and was widely sought out for identification of species in this order. Biography Uhler was born in Baltimore, Maryland, the son of George Washington Uhler and Anna Reese Uhler. His father was a prosperous merchant and his great-grandfather, Erasmus Uhler, emigrated to America and served in the Revolutionary War. Uhler's private schooling provided a strong background in Latin and German. He attended Latin School in Baltimore and then Baltimore College. Uhler's youthful interest in entomology started when he began collecting insects at the family farm near Reisterstown, Maryland, Reisterstown. His pursuit was encouraged by a family friend, John Gottlieb Morris, an amateur naturalist and the first librarian for the Peabody Institute. Although his father se ...

Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterised 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 coloration, 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, al ...

Libellulidae
The chasers, darters, skimmers, and perchers and their relatives form the Libellulidae, the largest family of dragonflies. 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 the most commonly encountered 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 tropical species in the genera '' Tr ...

Hot Springs
A hot spring, hydrothermal spring, or geothermal spring is a Spring (hydrology), spring produced by the emergence of Geothermal activity, geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through fault (geology), faults to hot rock deep in the Earth's crust. Hot spring water often contains large amounts of dissolved minerals. The chemistry of hot springs ranges from acid sulfate springs with a pH as low as 0.8, to alkaline chloride springs saturated with silica, to bicarbonate springs saturated with carbon dioxide and carbonate minerals. Some springs also contain abundant dissolved iron. The minerals brought to the surface in hot springs often feed communities of extremophiles, microorganisms adapted to extreme conditions, and it is possible that life on Earth had its origin in hot springs. Humans have made use of hot springs for bathing, relaxation, or medical therapy for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Libellula Saturata Nymph Needham 1904
''Libellula'' is a genus of dragonfly, dragonflies, called chasers (in English) or skimmers (in American), in the family Libellulidae. They are distributed throughout the temperate zone of the Northern Hemisphere. Many have showy wing patterns. Overview The taxa ''Ladona'' (corporals) and ''Plathemis'' (whitetails) have been considered as synonyms of ''Libellula'', subgenera, or separate genus, genera by different authorities. Recent phylogenetic analysis has supported their status as either subgenera or full genera.
