Morley's Final Catalogue: Somewhat scarce, and doubtless decling with our felled woodlands. Larvae in tolerable plenty in woods round Ipswich, and in woods near Stowmarket (Crewe, Nat. 1858, 37); but at neither Playford nor Brandeston (Gr). Sporadic at Copdock in 1896 (Hkg), Belstead; Bentley Woods singly in 1893-4 (Mly), 1895 (Baylis) and 1899 (Platten); Blaxhall, Needham, Ickworth, Downham (one larva on oak: Norgate); Mildenhall in 1936 (Gd) and Brandon.
