AJUGA. Bugles. [Lamiaceae]

Five species of Ajuga are recorded in Britain. These include the native Ground-pine (A. chamaepitys (L.) Schreb.), Pyramidal Bugle (A. pyramidalis L.) and Bugle (A. reptans L.). Ground pine is protected under Schedule 8 of the Wildlife and Countryside Act, 1981. Pyramidal Bugle is protected in Northern Ireland under Schedule 8 of the Wildlife (Northern Ireland) Order, 1985. Three dipterous miners, the agromyzids Amauromyza labiatarum, Amauromyza morionella and Trypeta zoe, are recorded on Ajuga in Britain. The agromyzids Liriomyza trifolii, a polyphagous pest species of ornamental and vegetable crops occasionally intercepted at UK points of entry, is recorded on Ajuga. It has been found under glass in England and Wales. All populations have been and continue to be eradicated. Elsewhere, in addition to the Lamiaceae-feeding agromyzids Amauromyza labiatarum and Amauromyza morionella, the polyphagous agromyzids Liriomyza bryoniae, Liriomyza strigata and Liriomyza trifolii are recorded mining Ajuga. Two non-dipterous miners are recorded on Ajuga in Britain (see below).

Key for the identification of the known Diptera mines in Britain.

1> Corridor mine following the mid-rib, with lateral offshoots. Pupation external. Puparium yellow Mine of Trypeta zoe on Artemisia vulgaris. Image: Willem Ellis (Source: Nederlandse bladmineerders) Trypeta zoe Meigen [Tephritidae]. -> 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. Puparium reddish-brown. Distinguishable from Amauromyza lamii only by the male genitalia. Mine of Amauromyza morionella on Ballota nigra. Image: Willem Ellis (Source Ellis (2002-7) Amauromyza (Amauromyza) morionella (Zetterstedt) [Agromyzidae]. -> A linear-blotch mine, first instar mine is linear, later developing into a conspicuous white blotch. Frass greenish diffused. Rubus fruticosus Filipendula ulmaria Mines of Amauromyza labiatarum. Images: Willem Ellis (Source: Nederlandse bladmineerders) Amauromyza (Trilobomyza) labiatarum (Hendel) [Agromyzidae].
