Hoverfly feeding, SEM Featured 20 Aug 1999 Image

Hoverfly feeding, SEM

Hoverfly feeding. Coloured scanning electron micrograph (SEM) of a hoverfly (Rhingia campestris) feeding on a bugle flower (Ajuga reptans). Its long mouthparts are seen reaching into the flower to suck its nectar. Some flowers may also be pollinated by feeding hoverflies. Its large compound eyes are red. At far right, one of its halteres (paddle-shaped) is visible. These tiny projections aid in the fly's balance. Hoverflies are so named for their ability to hover in the air by beating their wings (silver, centre right) rapidly. This is usually done, as here, to allow them to feed on flowers without alighting.
