35.028 Brachmia blandella (Fabricius, 1798)

Status and Distribution

Widespread and common over much of southern, central and eastern England, eastern Wales and the Channel Islands. Local over the rest of Wales and more southern parts of northern England. There were some indications that the species was pushing northward during the late 1990s and the first few years of the 21st century but any expansion of range seems to have faltered. Apparently absent from Ireland, Northern Ireland, Isle of Man and Scotland. A single 1970s record from central Scotland requires verification.

    Foodplant and Larval Feeding Signs

    Ulex europaeus (common gorse), see plant distribution map, and occasionally as a gall inquiline or in the seed-heads of Cirsium palustre.

    Within detached, withered gorse flowers lying amongst the spines of the bush, appearing to feed on the stamens.

    Utilises a wide range of habitats including grassland and woodland.

    Finding the Moth

    Larva: in a spinning on detached, withered gorse flowers lying amongst the spines of large old bushes. It has, on single occasions, been reared from collected insect galls on grand fir and from marsh thistle seed-heads. The final instar larva is similar to early instars of Agonopterix nervosa and, as with the Agonopterix larva, can wriggle in a rather violent manner, unusual in gelechiids. B. blandella larva are paler, a slightly different tone of brown to A. nervosa and do not grow longer than about 8mm. More details can be found in Heckford and Sterling, 2005 - see published papers. Additionally Anarsia spartiella and Blastobasis adustella larva have also been found feeding in decaying gorse flowers.

    Adult: can be beaten from old, large gorse bushes, flies at dusk and comes readily to light.

    Similar Species

    When at rest, the rather triangular shape with pointed wings and the mottled pale-brown appearance make this a distinctive species.
