Host
Reared from Anteon pubicorne (Dalman, 1818) (Waloff 1975, as Anteon lucidum (Haliday, 1828); Perkins 1976, as Chelogynus lucidus (Haliday, 1828)) and Lonchodryinus ruficornis (Dalman, 1818) (Dryinidae) (Waloff 1975, as Preanteon sp.; Olmi 2000), all from the United Kingdom. Moreover, one specimen was labelled as reared from a female of Streptanus sordidus Zetterstedt, 1828 (Cicadellidae) by V.H. Chambers.
Notes
Ismarus rugulosus is unusual in that almost all specimens are female, and it is possible that it is normally thelytokous. Only one male specimen, from Germany, was seen during this study.
