Fly orchid (Ophrys insectifera)
A number of orchid species use mimicry to attract their pollinators. Insect mimics have evolved to give themselves an advantage, as they don't have to compete to be pollinated like generalists but rather only need to attract a particular insect. O. insectifera is one such species, even impersonating the antennae and sheen on the folded wings of its pollinator. Flowering in May to June, it can be found in a number of calcareous grassland environments in the South Downs National Park.
