Moscas-das-flores (sirfídeos)
Syrphidae
Mosca
Registro em nível de família das moscas que imitam vespas e abelhas, que estão entre as visitantes de flores mais frequentes nos jardins da América do Norte e, depois das abelhas silvestres, são frequentemente consideradas o segundo grupo mais importante de polinizadores. Os adultos se alimentam de néctar e pólen e preferem flores rasas e acessíveis - umbelas de topo achatado de Apiaceae (zízia-dourada, funcho, endro) e flores compostas abertas de Asteraceae - que suas peças bucais curtas conseguem alcançar. As larvas de cerca de 40 por cento das espécies são predadoras de pulgões e de outros insetos de corpo mole, com uma única larva consumindo até várias centenas de pulgões ao longo de seu desenvolvimento de duas a três semanas, o que as torna importante controle natural de pragas ao lado de seu papel polinizador.
Conservação
Nenhuma espécie de sirfídeo está listada sob a Lei de Espécies Ameaçadas dos EUA, e a família como um todo é amplamente distribuída e comum. Estudos observam que a diversidade e o número de espécies especialistas caem acentuadamente em áreas de uso intensivo da terra, de modo que a ausência de listagens formais pode refletir em parte a pesquisa limitada, e não a inexistência de ameaças. Fornecer uma longa sucessão de flores abertas, ricas em néctar e pólen, é a ação de jardim canônica para apoiá-las.

Hoverflies are the visitor group most often overlooked on this kind of flower and are among the most numerous on it. A shallow open cyme with exposed nectaries suits a short mouthpart perfectly, and hoverflies are active in cool, part-shaded woodland-edge conditions where bee activity drops off - which is precisely the habitat this plant occupies. The larvae of many syrphids are aphid predators, so the same insects are working on the pest side of the garden as well.
Corniso-sedoso
De apoio / Plantas que esta espécie poliniza
Wikipedia names flies alongside bees among the pollinators, and the flower architecture explains why: a flat-topped cyme with tiny open flowers is the classic short-tongued-insect platform. Hoverflies are the most numerous of those visitors on shrub dogwoods, and their larvae are aphid predators, so the same plant is feeding an adult pollinator and subsidising pest control in the beds around it.

The open, accessible umbels are a classic hoverfly flower, freely visited for nectar and pollen.
Hoverflies are among the insects drawn to the open, nectar-rich flowerheads in summer, working them alongside the bees and butterflies.
Goldenrod flowers draw hoverflies and other flies among their pollinators; genus-level inference.
Hoverflies take nectar from the small, accessible flowers; their larvae are useful aphid predators, so the bloom helps draw beneficial insects into the border.
Hoverflies are common visitors to early, open, accessible flower clusters like these.
Hover flies and other generalist flower visitors also feed at the open golden heads early in the season.
Hoverflies are constant visitors to the flat, open daisy flower, taking both nectar and pollen from the exposed disc; their larvae are useful aphid predators in the garden.
Hoverflies are frequent visitors to the small, open, easily accessed flowers, and their larvae also prey on the spindle's aphid colonies - a double link to this shrub.
Hoverflies (whose larvae eat aphids) are drawn to the open, flat flower heads - a key reason yarrow is grown as a beneficial-insect 'insectary' plant.
Hoverflies are frequent visitors to small, open, easily accessed tree flowers like these in spring.
Short-tongued hoverflies readily feed at the open, shallow florets of the pincushion heads; their larvae are useful aphid predators in the surrounding meadow or border.
Hoverflies visit the open flowers for nectar and pollen; their larvae are useful aphid predators, so the long bloom supports beneficial insects as well as bees.
Hoverflies (Syrphidae) are among the documented visitors to Astrantia major's open, accessible florets alongside the beetles noted as primary pollinators in Wikipedia.

Hoverflies are common visitors to the broad, easily accessed cistus blooms.
Syrphidae are named on the Wikipedia visitor list, together with dance flies in the Empididae, which have no entry in this wildlife catalog and are recorded here in prose instead. Hoverflies are pollen feeders as adults and predators of aphids as larvae, so a flowering viburnum in a shaded bed feeds both halves of that life cycle - Wikipedia also notes that the plant attracts aphids.
Hoverflies feed at exactly this kind of flat exposed cyme and are abundant in May, which puts them among the likely visitors. The entry earns its place for a second reason: syrphid larvae are aphid predators, so the same flowers that feed the adults help keep the shrub layer around them clean.
Hoverflies are part of the documented European visitor community, with the long-snouted Rhingia rostrata specifically recorded - Rhingia is the one syrphid genus built to reach nectar at the bottom of a deep tube, and it does not yet have its own entry in this catalog, so it is named here rather than wired. The North American picture is the part worth carrying away: a yellow flag monoculture is not a pollinator planting. It replaces a diverse marsh flora with one clone of one species flowering for about six weeks, and the correct wildlife-value comparison is against what it displaced, not against bare ground.
