genus of orchids, family Orchidaceae, containing approximately 30 species of plants native to Eurasia and North Africa. All have metallic-coloured, hairy flowers that resemble insects. Each plant is less than 30 cm (1 foot) tall and bears several flowers on a single spike. Male insects attempt to copulate with the flowers, which resemble females of their own species. During this process, pollen sacs become attached to the insect's body and are transferred to the next flowers visited. The fly orchid (O. insectifera) and the bee orchid (O. apifera) are common European species. Some species of Ophrys are known as spider orchids (spider orchid) because their flower lips resemble the bodies of spiders.
