General comments:
Most species of Parnornix can be named reliably from their larval mines but in cases of difficulty the adults should be reared through for examination. However, almost wild-caught adults will be worn, to at least some degree, and in most cases we will insist on genitalia examination to obtain the correct species name.

Widespread and potentially ubiquitous. Usually abundant, though with occasional years with reduced numbers of larval cones. The conical folds are likely to be found on every hawthorn bush in the county and in the case of this species cannot be confused with anything else. Adults sometimes come to light traps.
