Corythuca arcuata var. This series was determined as C. cydoniae in 1954 by R.F. Hussey. With the exception of Hillsborough County, all Florida records are from the northern part. Adults are needed for confirmation since diagnostic keys do not exist for egg and nymphal stages of C. cydoniae and related species. Field identification of adults is difficult because thre are several similar species.
Specimens are small and pigmentation is variable within a species.
The most valuable diagnostic character is the straight hind margin of the apical, elytral crossbar. There are several records for June, July, September, and October. There are only two November records and one for August. Nymphs have been reported as early as 7 June and as late as 10 October. He found that the life cycle takes five to seven weeks, depending on the weather, and there was only one full generation per year.
