Mine: July, Nov-Dec

Pupa: Inside the leaf gallery as shown. The initial pupa formed is dark brown - see top photograph(and may be yellowish), but tends to blacken over the winter (as shown in the lower photograph). The posterior spiracles are distinctive - consisting of a long curving part which has two smaller bulbs entwining its base.

Notes: The mine is a long gallery which is formed mostly in the apical parts of the leaf.  Formerly Dizygomyza caricicola.

A close up of the gallery is here. Mines confirmed from adults (det.David Gibbs, reference collection) which emerged 6.iii.2005 indoors. Female adult retained, coll. Rob Edmunds
