Cannings: A review of the distribution and natural history of Apiocera barri and Nemomydas pantherinus (PDF-Datei; 2,4 MB) Aldrich, J.M. The most desirable territory, as measured by frequency of occupancy or male-male encounter rate, had the highest female visitation rate. Mating duration of large and small males was about 11 min even after numerous matings. (1968) Family My, Papavero, N. & Ibáñez-Bernal, S. (2001) Contributions to a history of Mexican Dipterology—Par. However, unusually large males are not concentrated at the peaktop, suggesting again that mating opportunities are no greater here than at lower-elevation hilltops. Patrolling in P. canadensis is an outcome of relatively high male density along the ridge, rendering territories in short supply, as shown by the observation that experimentally vacated territories are seized rapidly by formerly patrolling males. Die Mydidae sind eine Familie der Zweiflügler (Diptera) und gehören hier zu den Fliegen (Brachycera). SHIELDS, O.
Pan-Pac. The study of flies has figured prominently in major advances in the fields of molecular evolution, physiology, genetics, phylogenetics, and ecology over the last century.

Following sperm transfer (~87 min) and genital separation (~5 min), the female deposited and ingested two droplets containing spermatozoa (~6 min). Whereas most aspects of the copulation-oviposition cycle of P. litigata are characteristic of other necrophagous or scatophagous flies, the manner in which P. litigata females expel and ingest ejaculate materials after copulation has not been reported in any other-species of Diptera. Lamas , CJE and V. American genera and illustration of spermathecae. Territorial defense reduced interference from conspecific males during courtship.
Harten (ed. Bull US Natl Mus., 224(2): 433–907. Die erwachsenen Tiere leben meist auf offenem Sandboden in trockenwarmen Gebieten und nehmen Wasser und Honigtau auf, besuchen aber nur selten BlÃ¼ten.

The average duration of residence by a male wasp was 8 days for all occupants of 18 trees followed over the breeding period.
Alternatively, they may abandon territoriality altogether to patrol a series of trees along a ridge. This genus was originally erected to group four Neotropical species, namely G. apicalis (Wiedemann, 1830), G. autuorii Janeiro, Itatiaia.
Mississippi and especially from California. Der umgangssprachliche Name geht in erster Linie auf die Gattung Rhaphiomidas zurÃ¼ck, die nun allerdings nicht mehr zu der Familie gezÃ¤hlt wird. We are thrilled to invite you to apply for the Sao Paulo School of Advanced Sciences on Vaccines, an exciting course that will provide participants with a critical and comprehensive view of the state of the art in vaccine research. Males often wrestled for possession of females, but take-overs were rare.
The reindeer nose bot fly Cephenemyia trompe aggregates on hilltops/mountaintops to mate. The Dolichopodidae recorded from Colombia are listed based on literature data only and currently comprise 30 species in 14 genera (six subfamilies). Mellinger , GB. Gauromydas Wilcox, Papavero & Pimentel, 1989 are giant flies, and include the largest fly known, G. heros (Perty, 1833).
Some species are, linear and adjacent to a central callus (except in Megascelinae and Rhaphiomidinae); antenna with elongate, postpedicel, often with basal stalk and apical thickened club; palpus one-seg, often prolonged on apical spine; wing with apical branches of M peculiarly curved anteriorly, parallel to distal, Megascelinae and Rhaphiomididae); male hypopyg, The majority of the species occur in warmer clim, The adults are essentially flower feeders (Drury 1773; Zikán 1942, 1944; Rogers & Mattoni 1993; Williams.

To evaluate possible suppression of the fly population by killing males (by insecticides or traps) at such sites, the density of sites and the number of males at each site were monitored in a summer grazing area of the semidomestic reindeer host (Rangifer tarandus) in Finnmark, northern Norway.

Gerstaecker, A. D. scctrts McAtee (1921) was discovered in the White hits., New I-Iampshire; Strickland recorded the species from Alta. Individual males are active on mountain ridges for periods averaging about 3 weeks for those wasps captured in the first half of the flight season.
Meanwhile, the female emigrated to a part of the antler where density of single males was lower.
