Corydalus Cornutus
The eastern dobsonfly, ''Corydalus cornutus'', is a large insect in the Corydalidae family. It is found in eastern North America in regions with fast-flowing streams where its aquatic larvae develop. These are known as hellgrammites and are among the top invertebrate predators in the streams in which they live. They are used by anglers as bait. Distribution The eastern dobsonfly is found in most of eastern North America. It is usually found near the swift flowing, unpolluted streams in which its larvae develop. Common names The origin of the word "dobsonfly" is unclear. John Henry Comstock used the term in reference to this species in his 1897 book ''Insect Life'',Comstock, John Henry (1897). Insect Life. Cornell University Library. Online. but did not explain it.

American Robin
The American robin (''Turdus migratorius'') is a migratory bird of the true thrush genus and Turdidae, the wider thrush family. It is named after the European robin because of its reddish-orange breast, though the two species are not closely related, with the European robin belonging to the Old World flycatcher family. The American robin is widely distributed throughout North America, wintering from southern Canada to central Mexico and along the Pacific Coast. It is the state bird of Connecticut, Michigan, and Wisconsin. According to the Partners in Flight database (2019), the American robin is the most abundant bird in North America (with 370,000,000 individuals), ahead of red-winged blackbirds, introduced European starlings, mourning doves and house finches. It has seven subspecies, but only one of them, the San Lucas robin (''T. m. confinis'') of Baja California Sur, is particularly distinctive, with pale gray-brown underparts.

Hydra Viridissima
''Hydra viridissima'' is a species of cnidarian which is commonly found in still or slow-moving freshwater in the Northern temperate zone. ''Hydra viridissima'' is commonly called green hydra due to its coloration, which is due to the symbiotic green algae ''Chlorella vulgaris'' which live within its body. These creatures are typically 10 mm long and have tentacles that are about half of their length. They are strictly carnivorous and typically feed on small crustaceans, insects and annelids. ''Hydra'' are normally sessile and live on aquatic vegetation. They secrete mucous to attach to substrate using their basal disc. Anatomy ''Hydra'' are multi-cellular organisms. They are made up of two layers of epithelial cells and have a hypostome or mouth opening. Circling the mouth are tentacles that contain nematocysts or stinging cells to help in prey capture. The mouth and tentacles are called the hydranth. The rest of the ''Hydra'' is known as the column and is divided into four ...

Synanthedon Scitula
''Synanthedon scitula'', the dogwood borer or pecan borer, is a moth that is a pest of many plants including the dogwood and pecan. It is notorious due to the severity of damage it can cause and its widespread geographical distribution. Description and ecology Eggs ''Synanthedon scitula'' eggs are a light chestnut brown color and are 0.4 to 0.6 millimeters across. They are marked with a hexagonal pattern of lines. The eggs are laid singly by the mother and take 8–9 days to hatch. Larvae ''Synanthedon scitula'' larvae are cream colored with a red head. They pass through six instars ranging in length from 1 millimeter to 15 millimeters or more at the last instar. Soon after hatching they burrow into the burrknot tissue or areas around bark scales. As the dogwood borer larvae feed red frass is pushed to the surface. It collects and is pushed to the surface and held together by silk. Larvae overwinter in their feeding tunnel, and resume eating whenever the temperature exceeds 45 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic (inhabiting sea waters), some are benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult and then, after more molts, achieves adult development. The nauplius form is so ...

Rotifer
The rotifers (, from the Latin , "wheel", and , "bearing"), commonly called wheel animals or wheel animalcules, make up a phylum (Rotifera ) of microscopic and near-microscopic pseudocoelomate animals. They were first described by Rev. John Harris in 1696, and other forms were described by Antonie van Leeuwenhoek in 1703. Most rotifers are around long (although their size can range from to over ), and are common in freshwater environments throughout the world with a few saltwater species. Some rotifers are free swimming and truly planktonic, others move by inchworming along a substrate, and some are sessile, living inside tubes or gelatinous holdfasts that are attached to a substrate. About 25 species are colonial (e.g., ''Sinantherina semibullata''), either sessile or planktonic. Rotifers are an important part of the freshwater zooplankton, being a major foodsource and with many species also contributing to the decomposition of soil organic matter. Most species of the r ...
