Ophion undulatus Gravenhorst, 1829: 697. Ophion arcuatus Brullé, 1846: 146. Status
A very rarely collected species, found on southern coastal heaths where it has been reared from Lasiocampa trifolii(Denis & Schiffermüller, 1775) (Lasiocampidae). The host is now very local and E. undulatushas not been found in Britain since 1971.
Material examined ENGLAND: 1 ♀, 1 Ƌ, Dungeness ( VC15), ex Lasiocampa trifoliicoll. as larva 6 Jun. 1945(G. V. Bull) ( BMNH); 1 ♀, 1 Ƌ, Ilfracombe ( VC4), Jul. 1971(I.D. Gauld); 1 ♀, Lowestoft ( VC25), Jul. 1971(I.D. Gauld) (latter two records taken from Gauld, 1974; specimens not in BMNH). Additional material in NMS SPAIN: 1 ♀, Zaragoza, Montes de Torrero, 230 m, 24 May 1998(G.E. King).
Remarks Enicospilus inflexushas been separated from E. undulatuson the basis of differences in head shape ( Gauld 1974) which seem to be consistent, based on the limited material in BMNH. Although there may be a difference in host use, this is based on only two rearings of E. undulatus, from one place and date; although Lasiocampa trifoliiis rather smaller than L. quercus, E. inflexusand E. undulatusdo not differ significantly in size.
