Morley's Final Catalogue : The species is periodical and sometimes common during September and late August, just like the above M. stellatarum though it flies to flowers at dusk and not by day; it is regarded as usually migrating from the Continent for no very apparent reason, while the latter Hawk is cuddled as indigenous. An interesting point emphasised by our records is the small proportion of coast localities, which hardly supports the immigrant theory. Three in Stowmarket garden during 1847 and none through next decade (B); rather plentiful around Ipswich and two in Aldeburgh during 1859 (Fison, Ent. Wk. Int. vi, 194-5 ; cf. 187); abundant in Bury during 1868 (Suff. Inst, 4ly J. 1869, 23) and one in cemetery (Ent 1885, 295); Brandon, Stutton, Westerfield and common at Henley in 1898 (Sparke); frequent at Stutton and Ipswich in 1901 (Ent., Nov.); Waldringfield in 1906 (Wlr); Framlingham (Vinter, Ent. 1917, 260); a score at Benhall in 1920 (Gray); two at Gorleston in twenty years (D); fairly common at Needham in 1922 (Platten); one at Monks Soham in 1930 (in coll. Mly) ; Southwold in 1918,1922,1930 and 1931 (Collings). Unobserved occurrences are doubtless innumerable.
