Remarks
- Biology: Develops one annual generation on Ribes grossularia in Poland; hibernation is in the second instar nymph; young female and adult males appear in April - May; oviposition begins in June (Lagowska, 1994).
- Economic Importance: Lagowska (1984) found that the frequency and infestation rate on fruit trees in Lublin, Poland was higher in unprotected orchards than in protected ones.
- General Remarks: Good description and illustration of the adult female given by Tang (1991). Good description of the adult female given by Borchsenius (1957).
