Davey, P., 2009: A very rare immigrant species seen less than fifty times in Britain, headquartered in eastern Europe, in North Africa and southern Iberia, and an occasional transitory resident in central and southern Europe. The larva feeds on field wormwood (Artemesia campestris) and goosefoot (Chenopodium spp.). In Dorset, the moth has been seen on one occasion. "One in my garden. It was feeding in bright sunshine on a flowering plant, and although only about three feet from me, was very wary, it went into the next garden. I went in for a net, but though I followed it into the next garden, it would not give me a chance to net it." (W Parkinson Curtis): Branksome, by day on 23 July 1945. Of the British all-time total, thirty were seen in south-west England in May 1943 together with huge numbers of Striped Hawk1990; southern Iberia or Morocco were likely sources for this evidently spectacular immigration.
