Leaf-mine: An
initially linear mine, which at second instar develops into a large
whitish blotch with conspicuous black frass. The early linear mine
is frequently entirely enveloped by the blotch but is detectable
by the alternate irregular strips of frass. Pupation external (Spencer,
1976: 158).
The
first part of the mine consists of a long, slender upper-surface
corridor. After the first moult this changes into a large primary
blotch without feeding lines. Frass in the corridor in short, somewhat
angular thread fragments, towards the end even in grains. Frass
arranged less closely along the sides than in A.
lamii. Pupation outside the mine (Bladmineerders van Europa).
The frass is conspicuous in the mine and the mine is initially linear, then develops into a white blotch, often enveloping this early mine (British leafminers).
Larva:
The larva is described by de Meijere (1934) and illustrated in Bladmineerders van Europa.
Puparium:
Reddish-brown, deeply segmented; posterior spiracles on short conical
projections, each with 3 bulbs (Spencer,
1976: 158).
Comments:
Stachys officinalis is treated
as Betonica officinalis
(Betony) by Stace (2010).
