Apparently perennial, this species is almost exclusively parasitic upon Centaurea scabiosa, and is mainly found in chalk and limestone grassland. It may also form substantial populations in man-made habitats such as road verges, railway banks and quarries. Lowland.
There appears to have been a gradual contraction in the range of O. elatior, especially in areas outside its core range where populations tend to be small. Most losses are probably due to habitat destruction. The distribution is stable in its core areas.
Eurosiberian Temperate element, with a continental distribution in W. Europe.
