Diversity of the Scuttle Fly (Diptera: Phoridae) Communities in the Plantations of Moist Pine Forests of the Białowieża Primeval Forest and the Tuchola Forest (Poland)

Scuttle fly communities of pine plantations were investigated in 1986 and 1987 in two sites, Bia?owie?a Primeval Forest and Tuchola Forest. Flies were collected using yellow plastic bowls placed on the ground. Up to now 108 species were identifined, and 46 occurred on both sites. Although the number of species was very similar in Tuchola Forest (77) and Bia?owie?a Primeval Forest (75) species diversity was considerably lower on the former site (p<0.05). Ten dominant species were common: Megaselia brevicostalis, M. giraudii, M. manicata, M. nigriceps, M. pleuralis, M. pulicaria-complex, M. pumila, M. verralli, Metopina oligoneura and Triphleba opaca. Five of these were characteristic of both communities (Megaselia verrali , M. brevicostalis, M. pumila, Metopina oligoneura and Triphleba opaca). Similarity of qualitative composition for dominants was rather high (Sø = 0.67), but the quantitative similarity was low (Mo = 0.26). During two study seasons in the community of the Bia?owie?a Primeval Forest the dominance structure did not change markedly and Megaselia verralli was the dominant (over 20%). M. verralli was also the dominant (ca. 30%) in the communities in the Tuchola Forest in 1986, but next year M. pulicaria-complex (ca.50%) dominated. Most of the dominant species are multivoltines and generalists. In Tuchola Forest the disturbances caused by the chemical treatment against Neodiprion sertifer might be the main factor changing the dominance structure in the phorid community in 1987 (extremely high dominance of Megaselia pulicaria-complex).     

An unusually rich scuttle fly fauna (Diptera,Phoridae) from north of the Arctic Circle in the Kola Peninsula,N. W. Russia

64 species of Phoridae, in 6 genera, are reported from the Kola Peninsula, north of the Arctic Circle. The new species Megaselia elenae and Megaselia kozlovi are described. 33 species of Megaselia, only known from females, are given code numbers. Keys to the species of all the females of Megaselia and Phora are provided; and also a key to the males European Megaselia species with a notopleural cleft.     

Two new species of Phoridae (Diptera) whose larvae associate with large spiders (Araneae: Theraphosidae)

Two new species of Megaselia Rondani, M. dinwrphica Disney and M. praedafura Disney, are described from South America. Their larvae crawl around on the bodies and exuviae of Theraphosidae. Larvae of M. praedafura were observed moving on to the spider's prey while it was engaged in feeding from the same prey.     

New host record for three scuttle flies, Megaselia flava, M. kanekoi and M. gotoi (Diptera: Phoridae), on the poisonous fungus Amanita ibotengutake (Agaricales: Amanitaceae)

We identified three species of fungivorous scuttle fly –Megaselia flava, M. kanekoi and M. gotoi– from eight fruit bodies of a fungus, Amanita ibotengutake, which has not previously been recorded as the host of these flies.     

Taxonomy and First Records of Two <Emphasis Type="Italic">Megaselia</Emphasis> Rondani Species (Diptera: Phoridae) Preying upon Eggs of <Emphasis Type="Italic">Phyllomedusa iheringii</Emphasis> Boulenger (Anura: Phyllomedusidae)

Non-aquatic reproductive modes have evolved among frogs possibly favored by some advantages such as the avoidance of aquatic predators. These reproductive modes, however, make the egg clutches susceptible to terrestrial predators, among which Diptera larvae are some of the most harmful. The present work reports the predation by phorid flies of 22 egg clutches of Phyllomedusa iheringii Boulenger in the South of Brazil. Phorid specimens were identified as Megaselia bruchiana (Borgmeier & Schmitz) and Megaselia necrophaga (Enderlein), species that were reported previously to be associated with ants and dead beetles, respectively. Frog-feeding in these species is hypothesized to be use of an alternative seasonal food source. We amend the diagnoses of both Megaselia species and provide new illustrations to facilitate their identification. We also describe the male of M. bruchiana for the first time and associate males with females of both species.     

Occurrence of oriental flies associated with indoor and outdoor human remains in the tropical climate of north Malaysia

Flies attracted to human remains during death investigations were surveyed in north Peninsular Malaysia. Six families, eight genera, and 16 species were identified from human remains, with the greatest fly diversity occurring on remains recovered indoors. The total relative frequency of species was led by Chrysomya megacephala (Fabricius, 1794) (46%), followed by Chrysomya rufifacies (Macquart, 1842) (22%), Sarcophaga (Liopygia) ruficornis (Fabricius, 1974) (5%), Sarcophaga spp. (4%), Synthesiomyia nudiseta Wulp, 1883 (6%), Megaselia spp. (3%), Megaselia scalaris (Loew, 1866), (2%), Megaselia spiracularis Schmitz, 1938 (2%), and Chrysomya villeneuvi Patton, 1922 (2%). Hemipyrellia tagaliana (Bigot, 1877), Desmometopa sp., Megaselia curtineura (Brues, 1909), Hemipyrellia ligurriens Wiedemann 1830, Ophyra sp., Sarcophaga princeps Wiedemann 1830, Piophila casei (Linnaeus, 1758), and unidentified pupae each represented 1%, respectively.
