“…Species of Graphomyia are aquatic or semi-aquatic and have larvae that are saprophagous in decaying plant material. Some species of Coenosia, Lispe, Lispoides, and Spilogona have aquatic larvae that prey on a wide variety of small invertebrates in wetland habitats (95,111,158). Larvae of species of Schoenomyza are stem borers of sedges (158).…”

Although studies of freshwater entomofauna frequently do not include the biodiversity and ecological roles of higher Diptera, cyclorraphous flies are often numerous and species rich in wetlands. Seventeen families are commonly found in freshwater wetlands, with Ephydridae, Chloropidae, Sciomyzidae, Sphaeroceridae, and Scathophagidae being among the most important in terms of population size and species richness. Difficulty with sampling cryptic larval habitats and species identification challenges may account for the exclusion of acalyptrate and other dipterans from wetlands ecology studies. Large populations are facilitated by the high productivity of freshwater wetlands and the high intrinsic rate of increase characteristic of many species. Higher dipterans exist in all freshwater wetland types, are microhabitat selective, and play significant roles in food webs. The varied strategies for food acquisition and patterns of spatial and temporal distribution limit ecological overlap among the higher Diptera.

Adults of the anthomyiid Coenosia tigrina (Fab.), which are predators of flying insects including pest Diptera such as the onion maggot fly, feed on earthworms in the larval stage. The bionomics of C. tigrina females were studied in the laboratory at 15, 20, and 25°C, under different mating regimes. Adult female longevity slightly exceeded 1 month at 25°C and was close to 2 months at 15°C. Oviposition started 1–3 weeks after emergence, the delay tending to decrease with increased male presence. Females laid eggs at intervals of 1 to several days, in batches averaging 10–30 eggs depending on temperature. Fecundity reached an average of 230 eggs at 25°C with the sustained presence of males. Egg hatch decreased with the mother’s age, except when males were present for most of the female’s lifetime. Females exhibited maximal daily rate of predation at 25°C, but maximal lifetime predation was observed at 20°C. Male predation was less than females’, and female predation decreased with age. The time to eclosion decreased from 11 to 5 days as the temperature of egg incubation increased from 15 to 25°C. Larval weight at eclosion decreased with mother’s age. Postembryonic development and larval growth were studied at 15, 20, and 25°C, larvae being fed on four lumbricids. Development times decreased with increasing temperature between 15 and 25°C: from 35 to 15 days for larval development, and 28 to 12 days for pupal development. Males developed at a slower rate than females, but females weighed more at emergence. Larval survival was 30–60% on worm sections, and dropped to 17% on live mature Eisenia foetida (Sav.); but survival reached 90% on live, immature E. foetida 1–2 cm long. The larvae of C. tigrina penetrate the epidermis of earthworms, and feed internally with a preference for circulatory and chlorogogonous tissues.

Earthworm mucus stimulates oviposition in a predatory fly (Diptera: Anthomyiidae)

Coenosia tigrina larvae feed on earthworms. We hypothesized that earthworm mucus contains a kairomone that stimulates oviposition behavior in adultC. tigrina females, thus minimizing the search area in the soil required for newly eclosed larvae to find earthworms. In bioassays, adult females responded with extension of the ovipositor 25-43% of the time to earthworm-mucus-soaked filter paper disks compared to 6-7% in response to water-soaked disks. Ovipositor extension on mucus-soaked disks was followed by egg-laying 29% of the time and 0% of the time on water-soaked disks. Egg-laying byC. tigrina followed a diurnal periodicity, with most eggs laid in the latter half of the photophase even in the absence of earthworm mucus. More eggs were deposited from 1600 to 1800 hr by females given access to earthworm mucus during that period than were deposited by females not given access. There was no difference in the number of eggs deposited from 0600 to 0800 hr, by females given access to earthworm mucus or not. This is a time of day when few eggs are normally laid. This paper is the first report of an earthworm-produced kairomone in an insect-earthworm interaction. The kairomone may have potential for enhancing biological control of the onion maggot,Delia antiqua, which is a prey of adultC. tigrina.
