gall

Several orange larve together in a gall, that may be hairy; several overlapping generations. Part of the larvae pupates in the gall, in a white cocoon; another part hibernates in the ground and pupates in spring.

host plants

Plantaginaceae, monophagous

Veronica anagallis-aquatica, arvensis, bachofenii, beccabunga, catenata, chamaedrys, fruticans, longifolia, micrantha, montana, officinalis, polita, serpyllifolia, spicata, urticifolia.

larva

prosternum with spatula (from Möhn, 1955a)

synonyms

Cecidomyia, Dichelomyia, Perrisia, veronicae.

notes

The larvae of Dasineura similis and Jaapiella veronicae cannot be separated macroscopically, and their galls strongly overlap. Abnormally hairy gals of leaf buds and petioles probably invariably are caused by J. veronicae, smooth ones (mostly?) by D. similis. Both species may also occur in galled flowers, and can only tentatively be identified by association with vegetative galls.

inquilines

Macrolabis incolens.
