The leaf and stem mines of British flies and other insects

(Coleoptera, Diptera, Hymenoptera and Lepidoptera)

ANAGALLIS. Pimpernels and Chaffweed. [Primulaceae]

Two species, two subspecies and one sterile hybrid of Anagallis are recorded in Britain. These include Scarlet Pimpernel (A. arvensis), Garden Pimpernel (A. monelli), Bog Pimpernel (A. tenella) and Chaffweed (A. minima).

Only one British miner is recorded on Anagallis.

A key to the European miners recorded on Anagallis is provided in Bladmineerders van Europa.

insects (Diptera and non-Diptera) recorded on Anagallis

1 > Leaf-miner: Rather narrow corridor, untidy and sometimes branched, starting from the base of the leaf, in particular the midrib. Sides of the corridor irregularly eaten out, not really parallel. Frass mostly present, and then in a central line. The larva is capable of leaving the mine and start a new one elsewhere. These later mines are much broader, and the frass is scattered irregularly..

Host plants unknown in Britain. On numerous genera and species in several plant families, including Anagallis, elsewhere. Recorded in southern England. Widespread in continental Europe.
