Stem-mine: An external mine on stem or leaf stalk. Pupation either at leaf base or beneath epidermis of main stem (Spencer, 1972b: 31).

Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.

Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).

Posterior spiracles agree closely with those of O. orbiculata on Pisum (Spencer, 1972b: 31).

Hosts in Great Britain and Ireland:

Heracleum       Robbins, 1991: 67
Heracleum sphondylium Hogweed British Wild Flowers by John Somerville et al. Spencer, 1972b: 121

Hosts elsewhere:

Heracleum       Spencer, 1990: 160

Time of year - mines: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Widespread in south, but not common. Surrey (Bookham), Middlesex (Scratch Wood) and Berkshire (Silwood Park) (Spencer, 1972b: 31).

Distribution elsewhere: Widespread in continental Europe including Czech Republic, Estonia, French mainland, Lithuania, Poland, Slovakia and Spanish mainland (Fauna Europaea).
