SOLIDAGO. Golden Rods. [Asteraceae]

Twelve species of Solidago are recorded in Britain. These include the native Goldenrod (S. virgaurea) and eleven introduced Goldenrods including Canadian Goldenrod (S. canadensis) and Early Goldenrod (S. gigantea). Ten dipterous miners, the agromyzids Liriomyza eupatorii, Liriomyza pusilla, Liriomyza strigata, Nemorimyza posticata, Ophiomyia maura, Phytomyza solidaginis, the anthomyiids Pegomya depressiventris and Pegomya nigrisquama and the tephritid Cornutrypeta spinifrons, are recorded on Solidago in Britain. The agromyzids Liriomyza sativae and Liriomyza trifolii, polyphagous pest species of ornamental and vegetable crops occasionally intercepted at UK points of entry, are recorded on Solidago. Liriomyza trifolii has been found under glass in England and Wales. All populations have been and continue to be eradicated. Elsewhere the agromyzids Calycomyza humeralis, Liriomyza eupatorii, Liriomyza sativae, Liriomyza strigata, Liriomyza trifolii, Nemorimyza posticata, Ophiomyia maura, Phytoliriomyza arctica, Phytomyza solidaginis and Phytomyza virgaureae, the anthomyiids Pegomya depressiventris and Pegomya nigrisquama, and the tephritids Cornutrypeta spinifrons and Trypeta zoe are recorded mining Solidago. One non-dipterous leaf-miner is recorded on Solidago in Britain (see below).

#> Details of mine unknown. Pegomya depressiventris (Zetterstedt) [Anthomyiidae]. #> Details of mine unknown. Pegomya nigrisquama (Stein) [Anthomyiidae]. #> Details of mine unknown. Puparium yellow Mine of Cornutrypeta spinifrons on Senecio ovalis. Image: Willem Ellis (Source: Nederlandse bladmineerders) Cornutrypeta spinifrons (Schroeder) [Tephritidae]. 1> Mine primarily associated with the mid-rib. A distinctive mine with irregular short lateral offshoots into leaf blade. Pupation external.     Mines of Liriomyza strigata on Sonchus. Image: Crown copyright - courtesy of CSL Liriomyza strigata (Meigen) [Agromyzidae] -> Mine not primarily associated with the mid-rib. 2. 2> A linear mine commencing with a conspicuous regular spiral and then continuing a considerable distance more or less straight. Mine of Liriomyza eupatorii on Eupatorium cannabinum. Image: Willem Ellis (Source: Nederlandse bladmineerders) Liriomyza eupatorii (Kaltenbach) [Agromyzidae]. -> An irregular linear mine, which in small leaves can form a secondary blotch. Puparium orange Bellis perennis Solidago gigantea Mines of Liriomyza pusilla. Images: Willem Ellis (Source: Nederlandse bladmineerders) Liriomyza pusilla (Meigen) [Agromyzidae]. -> A large, brownish blotch, with conspicuous feeding lines. Pupation external. Puparium reddish-brown Mine of Nemorimyza posticata on Solidago gigantea. Image: Willem Ellis (Source: Nederlandse bladmineerders) Nemorimyza posticata (Meigen) [Agromyzidae]. -> A long, winding leaf-mine on the upper surface of the leaf, with frass widely-spaced in conspicuous black lumps. Pupation internal, at the end of mine. Puparium black or whitish-grey Mine of Ophiomyia maura on Solidago virgaurea. Image: Willem Ellis (Source: Nederlandse bladmineerders) Ophiomyia maura (Meigen) [Agromyzidae]. -> A conspicuous white mine with frass in more or less connected strips, older mines can show a conspicuous reddish-violet discolouration. Puparium black. Mine of Phytomyza solidaginis on Solidago virgaurea. Image: Willem Ellis (Source: Nederlandse bladmineerders) Phytomyza solidaginis Hendel [Agromyzidae]. -> A whitish linear mine, with frass predominantly in separate grains, rather than connected strips. Puparium black Phytomyza virgaureae Hering [Agromyzidae].
