Morley's Final Catalogue: This hawk's Suffolk headquarters are, or were before their recent contamination, the broad marshes of the Gipping valley; here Baylis found many larvae at Ipswich, Crewe 'once took about thirty on a small patch of Galium palustre' at Stowmarket (Nat. 1857), and it was quite abundant on that plant at Bramford in 1894 (Mly) and mid-August 1917 (Vinter).
Recent Suffolk Status: A widespread and sometimes abundant species in the county. One of Suffolk's commonest hawk moth species.
Life history: Single brooded in the summer.
Identification: Similar to Small Elephant hawk, but larger with greenish markings.
