Chromatomyia saxifragae (Hering, 1924)

Diptera, Agromyzidae

mine

Broad, tortuous corridor, usually upper-surface. The corridor may run several times through the leaf, crossing itself, and create a secondary blotch. Frass grains in groups along the sides of the corridor. Pupation mostly within the mine, in which case the front spiracula penetrate the epidermis.

hostplants

Saxifragaceae, monophagous

Saxifraga rotundifolia.

phenology

Larvae in May and July (Hering, 1957a).

BENELUX

Not known from the Benelux countries (Fauna Europaea, 2009).

distribution within Europe

Germany, Switzerland, Austria; Romania, Bulgaria (Fauna Europaea, 2009).

larva

Described by de Meijere (1926a, 1938a, 1941a) and Griffiths (1972a). Mandibles with two teeth, alternating. Both front and rear spiraculum two-armed, with about 26 and 22 papillae, respectively.

The description of the larva by Beri (1971e) is based on material from a plant of a widely different family (Acanthaceae) and has nothing to do with saxifragae.

puparium

Brownish yellow.

synonyms

Phytomyza saxifragae.

notes

Mountain species.
