Males cannot be determined to species via dissection, so will be a "group id" comprising hohenwartiana, parvulana and fulvana. Females, in addition to the annotated notes on the comparison image, the relative lengths of the apophyses can also be used to get to species. For hohenwartiana the anterior length is 72% that of the posterior, for parvulana it is 93% and fulvana 116% (this % may vary slightly). Wing length is 15-22mm for hohenwartiana, 14-19mm for parvulana and 19-25mm for fulvana and fulvana is paler.
