EUPHRASIA.
Eyebrights. [Scrophulariaceae]
|
Twenty-one
species of Euphrasia are recorded in Britain. All except
one are native. The BSBI provide a downloadable plant crib for Euphrasia.
Only one British miner is recorded on Euphrasia.
The
agromyzid Phytomyza
affinis is recorded in Co. Clare and elsewhere feeding in
the seeds of Euphrasia.
A key to the European miners recorded on Euphrasia is provided in Bladmineerders van Europa.

Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Euphrasia
|
1 > Leaf-miner: Oviposition takes place in an upper leaf and a short mine is formed
either in the leaf or stem, but the larva feeds primarily in the
stem. Pupating in the stem (Spencer,
1976: 487 (fig. 857), 488).
Short
and narrow corridor in the leaves, bracts or even calyx, ending
in a thick vein. From there the larva descends as a borer. Infested
plants largely die off. Pupation and hibernation within the mine. |
On Odontites, but not yet on Euphrasia, in Britain and Euphrasia, Melampyrum, Odontites and Rhinanthus elsewhere. Distribution in Britain unknown.
Widespread in continental Europe. Also recorded in Canada.
