Teasel (Dipsacus fullonum) being pollinated by marmalade hoverflies (Episyrphus balteatus). The teasel flowers open in a band around the centre of the egg shaped flowerhead which expands both up and down until all the flowers have emerged. The large plant produces several heads that dry out and persist over winter, the seeds of which are a favourite food of goldfinches. The marmalade hoverfly is common in Europe, North Asia and North Africa. Its larvae prey on aphids and the fly is quite an important flower pollinator. It hibernates in cold weather but can be seen on warm days throughout the year in Britain. Photographed in the UK.
