Phytomyza angelicivora Hering, 1924

mine

Untidy, irregularly lined corridor. The mine begins as an indistinctly visible lower surface epidermal corridor; later it turns into a short, broad upper-surface corridor along the leaf margin. Frass partly in pearl chains. Mine in the freshly unfolded leaves (Hering, 1957a). Hering (1924b) gives a picture of the mine.

host plants

Apiaceae, narrowly monophagous

Angelica palustris.

Although Hering (1924b) states in the original description that he bred the species from A. sylvestris, and among other the botanist Buhr (1932a) mentions sylvestris as the only hostplant, Hering later (1955b, 1957a) asserts that the only host plant is A. palustris. This is confirmed by Griffiths (1973c).

phenology

Larvae in May-June (Hering, 1957a).

BENELUX

Not known from the Benelux countries (Fauna Europaea, 2008).

distribution within Europe

With certainty known only from Germany (Fauna Europaea, 2008).

larva

Described by de Meijere (1938a:94-95, as Phytomyza sp.). Possibly also the description of “angelivora” by de Meijere (1926a:244-245) does indeed refer to this species too.

notes

In 1926 de Meijere (1926a) reports having bred Phytomyza obscurella from Angelica sylvestris. Later (1937a) het reconsiders his identification, and believes that Ph. angelicivora is concerned. Now it seems to emerge that the only host plant of the species is A. palustris, a Central-European species that does not come further to the west than Central Germany, we must concluded that de Meijere was mistaken. Judging by his illustrations of the rear spiraculum he had P angelicastri or P. archangelicae in front of him. For the moment there is no reason to maintain angelicivora on the Dutch list.
