Hydrometra stagnorum, the common water-measurer, is a species of aquatic bugs in the family Hydrometridae, the water measurers. [1] [2] [3] [4] [5]
This species is found in numerous European countries, including Hungary and Austria. [6] In Great Britain it is quite common in Leicestershire and Rutland. [7]
Hydrometra stagnorum is normally wingless, but sometimes has full wings. It is often dark greyish or even black in colour, and grows to approximately 13mm. The head and body are long and thin. Its antennae appear similar to a fourth pair of legs. [7]
This species lives at the vegetated margins in slow moving streams, as well as ditches and ponds. It lives close to the emergent stems of plants, upon which it lays its eggs. [7]
As adults, rows slowly over the surface of the water in search of prey. It seeks mosquito larvae and water fleas directly below the surface film. It catches these by spearing them through the surface of the water. [7]
This species can jump if disturbed. [7]
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion.
Hemiptera is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera.
The Hula painted frog is a species of frog endemic to the Lake Hula marshes in northern Israel. It is the only living member of the genus Latonia, which is otherwise known from fossils from Europe spanning from the Oligocene through Pleistocene. The Hula painted frog was thought to be extinct as a result of habitat destruction during the 1950s until the species was rediscovered in 2011.
The pumpkinseed, also referred to as sun perch, pond perch, common sunfish, punkie, sunfish, sunny, and kivver, is a small to medium–sized freshwater fish of the genus Lepomis, from the sunfish family (Centrarchidae) in the order Centrarchiformes. It is endemic to eastern North America.
The broadnose sevengill shark is the only extant member of the genus Notorynchus, in the family Hexanchidae. It is recognizable because of its seven gill slits, while most shark species have five gill slits, with the exception of the members of the order Hexanchiformes and the sixgill sawshark. This shark has a large, thick body, with a broad head and blunt snout. The top jaw has jagged, cusped teeth and the bottom jaw has comb-shaped teeth. Its single dorsal fin is set far back along the spine towards the caudal fin, and is behind the pelvic fins. In this shark the upper caudal fin is much longer than the lower, and is slightly notched near the tip. Like many sharks, this sevengill is counter-shaded. Its dorsal surface is silver-gray to brown in order to blend with the dark water and substrate when viewed from above. In counter to this, its ventral surface is very pale, blending with the sunlit water when viewed from below. The body and fins are covered in a scattering of small black & white spots. In juveniles, their fins often have white margins.
Hydrometridae is a family of semiaquatic insects, known as marsh treaders or water measurers. They have a characteristic elongated head and body which makes them resemble a yardstick for measuring the water surface.
Nymphargus grandisonae is a species of frog in the family Centrolenidae. It is found in Andes of Colombia and Ecuador. Its natural habitat is tropical moist montane forest ; larvae develop in streams and still-water pools. Its habitat is threatened by habitat loss, introduced fish, and agricultural pollution, but it is still a common species not considered threatened by the IUCN.
The ebony jewelwing is a species of broad-winged damselfly. One of about 150 species of Calopterygidae, it is found in the eastern U.S. and southeastern Canada, ranging west to the Great Plains. Other common names include black-winged damselfly.
In the 10th edition of Systema Naturae, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". True bugs and thrips were brought together under the name Hemiptera.
Aquarius remigis, known as the common water strider, is a species of aquatic bug. It was formerly known as Gerris remigis, but the subgenus Aquarius was elevated to generic rank in 1990 on the basis of phylogenetic analysis. Aquarius remigis is found throughout North America, but is most prevalent in the mid-west of the United States.
Oebalus pugnax, the rice stink bug, is a flying insect in the shield bug family Pentatomidae native to North America that has become a major agricultural pest in the Southern United States. It has been a known pest since at least the time of Johan Christian Fabricius, who described the species in 1775.
Lestes congener is a species of damselfly in the family Lestidae, the spreadwings. It is known by the common name spotted spreadwing.
Panulirus penicillatus is a species of spiny lobster that lives on shallow rocky and coral reefs in the tropical Indo-Pacific region. Common names for this spiny lobster include variegated crayfish, tufted spiny lobster, spiny lobster, Socorro spiny lobster, red lobster, pronghorn spiny lobster, golden rock lobster, double spined rock lobster and coral cray. It has a very wide range and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Hydrometra australis is a species of water measurer in the family Hydrometridae. It is found in the Caribbean Sea, Central America, and North America.
Hydrometra is a genus of water measurers in the family Hydrometridae. There are more than 120 described species in Hydrometra.
Hydrometra martini is a species of water measurer in the family Hydrometridae. It is found in North America.
Microvelia macgregori is a species of true bug in the family Veliidae. It is semi-aquatic, living on the surface of water in freshwater habitats in New Zealand.
Hydrometra gracilenta, the lesser water-measurer, is a species of aquatic bugs in the family Hydrometridae.
