Related species

Almost 80 species from around the world are currently placed in Anaphothrips, but only two are established in Britain, with a further five species recorded from elsewhere in Europe (zur Strassen, 2003). There are 17 Anaphothrips species known from North America, all living on grasses (Nakahara, 1995), and 43 from Australia, mostly living on plants other than grasses (Mound & Masumoto, 2009). This Australian species differs from the two native British species in lacking a comb on the posterior margin of tergite VIII.

Biological data

Feeding and breeding on leaves of Anigozanthos species, and possibly other members of Haemodoraceae from Australia.

Distribution data

Not a British species, but native to Western Australia, this has been taken once only in Britain. A single adult female was found under glass at the Royal Botanic Gardens, Kew, on Anigozanthos rufus recently imported from Australia (Collins, 2010a).
