Pherbellia
''Pherbellia'' is a genus of 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 '' A. fergusoni'', and then 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 pulmonate snails, ''P. prefixa'' preys on the mossy ...

Pherbellia Schoenherri
''Pherbellia schoenherri'' is a species of fly in the family Sciomyzidae. It is found in the Palearctic . The females lay eggs on the shells of Succineidae including '' Succinea putris''. The resultant larvae consume the animal and pupate within the shell.Bratt, A. D., L.V. Knutson, B. A. Foote, and C. O. Berg, 1969 Biology of ''Pherbellia'' (Diptera: Sciomyzidae).''Cornell Univ. Agric. Exper. Sta., New York State Coll. Agric. Ithaca, N.Y. Mem.'' 404, pp. 1-247; 184 figures. ''P. schoenherri'' is a very common and widespread species with a very long flight period. It flies mainly from April to October, but in most European countries, it occurs all year round and in a very wide variety of both dry and moist habitats.

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.

Sciomyzidae
The family Sciomyzidae belongs to the typical flies (Brachycera) of the order Diptera. They are commonly called marsh flies, and in some cases snail-killing flies due to the food of their larvae. Here, the Huttoninidae, Phaeomyiidae and Tetanoceridae are provisionally included in the Sciomyzidae. Particularly the latter seem to be an unequivocal part of this group and are ranked as tribe of subfamily Sciomyzinae by most modern authors, while the former two are very small lineages that may or may not stand outside the family and are provisionally ranked as subfamilies here. Whether the Salticellinae and the group around ''Sepedon'' warrant recognition as additional subfamilies or are better included in the Sciomyzinae proper is likewise not yet entirely clear. Altogether, the main point of contention is the relationship between the "Huttoninidae", "Phaeomyiidae", Sciomyzidae '' sensu stricto'', and the Helosciomyzidae which were also once included in the Sciomyzidae.

Succinea Putris
''Succinea putris'' is a species of small air-breathing land snail in the family Succineidae, the amber snails. Description The 10-17 (27) x 6-8 mm has 3-4 whorls. These are relatively flat and with shallow sutures. The body whorl is massive and the aperture is much greater than 50% of shell height. The spire is small. In color the shell is amber yellow. The visible soft parts are yellow with a reddish hue, which becomes lighter downwards to the sides. The animal can also be dark grey.

Parasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
