“…Keywords Wetland Á Sciomyzidae Á Hydroperiod Á Vegetation structure Á Stochastic sampling variables Introduction There has been much interest in the ecology of flies of the family Sciomyzidae (Berg and Knutson 1978), largely as a result of the obligate malacophagy observed in the majority of their larvae (Berg 1953). This gives them potential as bio-control agents of snail-borne trematode diseases of humans (Barker et al 2004;Appleton et al 1993) and livestock (Gormally 1988;Mc Donnell et al 2005) and of some gastropod agricultural pests (Coupland and Baker 1995).…”

Factors affecting Sciomyzidae (Diptera) across a transect at Skealoghan Turlough (Co. Mayo, Ireland)

Sciomyzid flies, which have potential as bio-indicators, were sampled by sweep-net surveys at a turlough in the west of Ireland. Turloughs are ephemeral wetlands (unique to Ireland), which flood from groundwater in winter and empty in the summer, during that time, they are frequently grazed.The weekly survey consisted of ten linear sweeps (5 m 9 1 m) in each of six homogeneous and contiguous vegetation zones throughout the summer of 2004. The fauna was dominated by univoltine species with Ilione albiseta being particularly abundant, though species displaying a range of phenologies and life histories were also present. Species richness and total abundance were significantly higher in the two zones with the highest hydroperiods. Mantel tests showed that the species matrix was significantly co-structured with permanent features of the physical environment, but not with stochastic sampling variables related to weather conditions. Mantel correllograms displayed typical patterns of autocorrelation for hydroperiod, soil moisture and soil pH in each zone and vegetation height, vegetation length and Ellenberg moisture index (weighted for vegetation composition) in each sweep-path. No patterns of autocorrelation were evident for distance among zones, area of patch of vegetation zone sampled, area of the vegetation zone on the whole turlough, soil mass-loss-on-ignition and Ellenberg N and reaction indices. These results provide strong evidence for high microhabitat specificity in Sciomyzidae at this site and indicate a major influence of vegetation structure and hydrological regime on their ecology.

“…No known sciomyzid larva occurs regularly underground or beneath mat vegetation such as Sphagnum. The larvae of the approximately 200 species of Sciomyzidae that have been reared are predators or parasitoids of Mollusca in nature (Berg & Knutson 1978). Only Salticella fasciata (Meigen) has been observed to feed on non-molluscan organisms in the laboratory, but in nature the adults oviposit on the shells of living snails, and the larvae feed on those snails (Knutson et al 1970).…”

Biology and immature stages of Helosciomyza subalpina (Diptera: Helosciomyzidae), an ant-killing fly from New Zealand

Biological features of adults and immature stages of Helosciomyza subalpina Tonnoir & Malloch are discussed. Information on habitat, geographical distribution, larval behaviour and feeding habits, natural enemies, and phenology are presented. The species is found in marshy areas in the South Island and on the Chatham Islands. In the laboratory, newly hatched larvae feed on a variety of freshly killed insects, and apparently lap up liquids from the integument of live ant larvae. Older fly larvae feed on decaying as well as freshly killed insects, and are overt predators of ant larvae. In the field, fly larvae and puparia have been found in association with ant nests; many puparia have also been found well away from ant nests. The egg, three larval instars, and the puparium are described. The taxonomic position of the Helosciomyzidae is discussed in the light of these new data on biology and morphology.

“…Newly hatched first-instar larvae do not float just beneath the surface film of a body of water while maintaining spiracular contact with the air, as do most reared species of Tetanocerini (Berg & Knutson 1978). Instead, they pass through the surface film and, like the fingernail clams (Bivalvia: Sphaeriidae) that they prey on, remain fully submerged.…”

Taxonomy of the New Zealand genusEulimnia, and biology and immature stages ofE. philpotti(Diptera: Sciomyzidae)

The endemic New Zealand genus Eulimnia and its two species are redescribed. Data are presented on the life cycle of E. philpotti Tonnoir & Malloch, and the habitat, geographical distribution, phenology, and biological features of adults and immature stages are discussed. Adults are found in permanently wet marshes, where the larvae prey on fingernail clams (Bivalvia: Sphaeriidae) while completely submerged. Mature larvae form puparia among vegetation or debris above the water level. The immature stages of E. philpotti are described. The genus is placed in tribe Tetanocerini, and its taxonomic position is discussed.
