Introduction

The St. Johnswort Inchworm was introduced in Canada in the 1980's as a potential biological control for the common St. Johnswort (Hypericum perforatum). "This species varies considerably in size (wingspan 37–43 mm) and colouration but is generally grey with three characteristic dark fascia across each forewing. The hindwings are pale grey or buff...The larva is also very variable, being green to reddish brown with alternating darker and lighter stripes." (Wikipedia 2012).
