The Ophrys frelon or bumblebee is a small Ophrys in size (often 10 to 20 cm, sometimes up to 30 cm and exceptionally 40 cm). The shape is stocky and the flowers are generally few in number (2 to 10). The labellum has a characteristic trapezoid shape, and it is covered with variable hairs and patterns. Note the two atrophied petals generally concolorous (pink) with the sepals at the back. Petals and sepals can be white but always concolorous. The lateral sepals are sometimes "pointed" but can also be very rounded, so this is not an important criterion for identification. The sepals are less extensive than for the Ophrys abeille but there is little risk of confusing them due to the general appearance of the flower. Also note the very visible yellow appendage at the tip of the labellum.

This Ophrys is more easily seen in eastern France but it is present in other French departments (a little over half). In the Alps, it is found below 1400 meters. Grows on fresh to dry land. It is found on sufficiently drained embankments or roadsides, in wasteland and sometimes in very shaded meadows.
