Seventeen of these were common to both the Kiuic and the Tabi areas: Tabanidae, Stratiomyidae, Asilidae, Culicidae, Mycetophilidae, Tachinidae, Muscidae, Tipulidae, Anthomyiidae, Bombyliidae
, Tanypezidae, Syrphidae, Sciaridae, Pipunculidae, Chironomidae, Dolichopodidae, and Conopidae.
Members of the subfamily Usiinae (Bombyliidae
) are readily separated from those of closely related bombyliid subfamilies by the flagellum which has a subapical sulcus bearing a style and without dorsal or ventral prongs, and by the absence of vein M2 (i.e., with three posterior cells); furthermore, members of the genus Parageron Paramonov, 1929 are separated from those of other usiine genera by the flagellum which has the subapical sulcus containing only a style and the spine-like arista (spine-like second flagellomere) is absent or fused and bumplike on apical margin of flagellum, also by the female spermathecal reservoir which is obpyriform (Evenhuis, 1990; Greathead and Evenhuis, 2001).

Ashman and Stanton (1991) detected significantly higher pollen-deposition rates by Bombus bifarius than Bombyliidae
. These authors also documented temporal variation in components of pollination effectiveness, as was found for pollinating moths by Pettersson (1991) and for pollinators of A.
The authors thank David Notton (BMNH), Neal Evenhuis (Bishop Museum, Hawaii, USA), curator of the USNM Bombyliidae
collection, and Claudio Jose Barros de Carvalho (DZUP), for loaning us specimens of Heterostylum.

Parasitism was observed in 17 cells (20.00%), of which six (7.06%) were attacked by Sarcophagidae, five (5.88%) by Bombyliidae
, two (2.35%) by Chrysididae, one (1.18%) by Eulophidae and three (3.53%) by non identified parasites.
Flies of the family Bombyliidae
and Syrphidae exploit flowers as a source of food.
Flies (particularly Bombyliidae
) occasionally have been reported to visit cactus flowers (Johnson, 1992; McIntosh, 2005; Strong, 2005), but they have not been considered as potential pollinators most likely because they do not fit the bee-pollination syndrome proposed by earlier investigators (Grant and Grant, 1979x, 1979b; Grant and Hurd, 1979; Grant et al., 1979).
The parasitoids from the families Bombyliidae
(Diptera) and Chalcididae (Hymenoptera), were identified by Carlos Jose Einicker Lamas (Museu de Zoologia, Universidade de Sao Paulo, Sao Paulo-SP, Brazil), and Marcelo Teixeira Tavares (Universidade Federal do Espirito Santo, Vit6ria-ES, Brazil), respectively.
