Phytomyza spondylii/pastinacae agg.

Description

The larvae of Phytomyza spondylii and Phytomyza pastinacae produce identical conspicuous, whitish linear mines on the leaves of their larval food plants, especially Hogweed. The mines cannot be reliably separated to species level and for this reason we have created this page which treats them as an aggregate. It is necessary to rear through the adult and subject it to detailed examination in order to identify it to species level.  If this has not taken place you should add your records to this aggregate page.

Identification difficulty

Adult Leafmine (if recorded to aggregate level - cannot be identified to species level with certainty from the leaf mine.)

Habitat

Around larval food plants, especially Hogweed.

When to see it

Mines can be seen from May to November.

Life History

Larva exits the mine through the lower surface and falls from the leaf on pupation.

UK Status

Widespread and fairly frequent in Britain.

VC55 Status

Status in Leicestershire and Rutland not known.
