72.087 [B&F: 2460] Passenger (Dysgonia algira) (Linnaeus, 1767)

 

Very rare immigrant from southern Europe, appearing in south-eastern England. Until 1980 there had been just two records: near Dover, Kent in August 1967 and at Bradwell-on-Sea, Essex in September 1969, but recorded nine times in Britain between 1981 and 2005, with an unprecedented 12 further records in 2006. In our area first recorded at Totland, Isle of Wight on 12 September 2006, with another on the island in 2018; the first for the mainland was in the same year, on 4 September in Wickham Common. Wingspan 44-48 mm. The most likely confusion species is Geometrician Prodotis stolida has forewing antemedian fascia without central compression and the postmedian fascia doubly curved; hindwing with a clear white spot above termen (MBGBI Vol 10). Observers are reminded that the very similar D. torrida (see Lepiforum) is a potential migrant although not reported from the British Isles to date. Larva feeds on Bramble and Sallow, no evidence of breeding in the UK.
