Fraxinus angustifolia subsp. oxycarpa, Moldova; from Hering (1932g)

mine

Fine, not too tortuous, upper-surface, quickly widening gallery. Frass as small rods regularly at either side. Pupation external (picture above).

hostplants

Oleaceae, monophagous

Fraxinus angustifolia subsp. oxycarpa (= “F. pannonica”), pallisiae.

Hering (1932g) attributes the mine to F. excelsior, but his picture shows that the leaflets have as many thoothlets as lateral veins, which indicates angustifolia.

phenology

Larvae until August (Hering, 1957a), but Skuhravá & Roques (2000a) report adults in April.

distribution within Europe

Moldova and Bulgaria (Fauna Europaea, 2010); mentioned by Hering (1960a) from Romania, and found by Süss (1999a) in Sicily; France (Reymonet & Ellis, 2019a).

larva

Posterior spiraculum with three papillae; mandible with two teeth, the distal one on the longest, right mandible quite long, reminding a Liriomyza (Hering, 1960a). See also Papp & Černý.

synonyms

Aulagromyza, Paraphytomyza fraxini.

notes

Until the description of the adult by Beiger known only as mine.
