Hitchhiker. Has been found on apple fruit packages exported from New Zealand.


Brassica spp., Medicago sativa (alfalfa), Trifolium dubium, T. pratense, T. repens (clovers), and Poaceae such as: Avena sativa (oat), Bromus, Hordeum sativum (barley), Lolium, Secale cereale (rye), Triticum aestivum (wheat). The following weeds have been reported as hosts: Anagallis arvensis, Calandrinia caulescens, Capsella bursa-pastoris, Cassinia leptophyla, Chenopodium album, Coronopus didymus, Hieracium, Polygonum aviculare, Rumex acetosella, Senecio inaequidens, Silene gallica, Soliva sessilis, Spergularia rubra, and Stellaria media. It is also suggested that the presence of mosses (e.g. Ceratodon, Sphagnum, Polytrichum spp.) may be crucial for the overwintering period.
