Pherbellia Melanderi
''Pherbellia'' is a genus of fly, flies in the family Sciomyzidae, the marsh flies or snail-killing flies. They occur throughout the world, except for the Subantarctic region. Like many Sciomyzidae, species of this genus have larvae that are predators or parasitoids of snails. The larva of ''P. albovaria'', for example, eats land snails such as ''Anguispira alternata'' and ''Anguispira fergusoni, A. fergusoni'', and then puparium, pupates in the empty shell. The ''P. albocostata'' larva eats up to five snails and then pupates in the ground litter next to the last empty shell. The larva of ''P. inflexa'' attacks the glass snail ''Zonitoides arboreus''. ''P. punctata'' is a parasitoid on the amber snail ''Succinea putris''. ''P. anubis'' larvae feed on several types of freshwater snails along the edges of ponds and marshes. Several ''Pherbellia'' are predators of the pond snail ''Stagnicola palustris''. While most snail-killing flies target land and freshwater pulmonata, pulmonate ...

Pherbellia Cinerella
''Pherbellia cinerella'' is a species of fly in the family Sciomyzidae. It is found in the Palearctic . ''P. cinerella'' is a dark and very characteristic ''Pherbellia'' and easy to recognise in the field by its long mid-frontal stripe and darkened anterior wing margin. The larva is predatory on a variety of terrestrial and aquatic snails including Helicidae, ''Galba truncatula'', ''Helix'', ''Helicella'', ''Succinea'' and ''Lymnaea''.There is little or no host preference. It is found in a wide range of habitats but it is most often found in warm and dry habitats such as coastal dunes and calcareous grassland where it can reach high numbers. It is also encountered in moist vegetation though in lesser numbers.Bratt, A. D., L.V. Knutson, B. A. Foote, and C. O. Berg, 1969 Biology of ''Pherbellia''(Diptera: Sciomyzidae).''Cornell Univ.

Marsh
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. This biological productivity means that marshes contain 0.1% of global sequestered terrestrial carbon. Moreover, they have an outsized influence on climate resi ...

Camillo Rondani
Camillo Rondani (21 November 1808 – 17 September 1879) was an Italian entomologist noted for his studies of Diptera. Early life, family and education Camillo Rondani was born in Parma when the city was part of the French Empire Napoleon having crowned himself King of Italy. The Rondani family were wealthy landowners and of "rich and of ancient origins" with ecclesiastical connections preliminary. Camillo's early education was in a seminary. He then passed into the public school system where, encouraged by Macedonio Melloni his physics and chemistry teacher in the preparatory course for the University of Parma, he did not attend the law lessons though his family had insisted. He attended mineralogy classes given by a Franciscan priest Father Bagatta and was taught natural history, a complementary course to botany for Medicine and Pharmacy. The Reader of Botany to the Athenaeum Parmesan was Professori Giorgio Jan, assistant at the Imperial Museum in Vienna and holder of the ...

Valvatidae
''Valvatidae'', the valve snails, is a taxonomic family of very small freshwater snails with an operculum, aquatic gastropod mollusks. Taxonomy The family Valvatidae has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). Genera The type genus of this family is ''Valvata'' O.F. Müller, 1774.

Operculum (gastropod)
The operculum (; ) is a corneous or calcareous anatomical structure like a trapdoor that exists in many (but not all) groups of sea snails and freshwater snails, and also in a few groups of land snails; the structure is found in some marine and freshwater gastropods, and in a minority of terrestrial gastropods, including the families Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc. The operculum is attached to the upper surface of the foot and in its most complete state, it serves as a sort of "trapdoor" to close the aperture of the shell when the soft parts of the animal are retracted. The shape of the operculum varies greatly from one family of gastropods to another. It is fairly often circular, or more or less oval in shape. In species where the operculum fits snugly, its outline corresponds exactly to the shape of the aperture of the shell and it serves to seal the entrance of the shell. Many families have opercula that are reduced in size, and which a ...
