Thorpe, W.H. 1934 The biology and development of Cryptochaetum grandicorne (Diptera), an internal parasite of Guerinia serratulae (Coccidae).. Quarterly Journal of Microscopical Science. London 66: 273-304.

Notes: C. grandicorne appears to be confined to a single host, G. serratulae. Oviposition has been manipulated to occur on Icerya purchasi, but development was not completed. Other records, on Icerya seychellarum and Warajicoccus (Drosicha) corpulentus, are doubtful.
