Common NameHonest PeroSeasonalityIn Alberta from late May to late June, with the peak flight in mid June.IdentificationThe robust body and dissimilar fore- and hindwing pattern of Pero species are more reminiscent of noctuids than geometrids. Forewing light grey-brown with a broad wavy dark brown median band and a white discal spot. Hindwing light grey with a pale bordered, slightly darker basal half and a row of small black terminal dots. Wing margins slightly serrate.
Very similar to P. morrisonaria, but with less overall speckling and the median band with a less pronounced paler area near the costal margin. The outer margin of the median band is straight near the anal margin and angled more towards the body in honestaria, while morrisonaria has a tooth-like indent near the anal margin (at the anal vein). In the southern mountains in Alberta, where P. behrensaria occurs with honestaria, these two should be distinguished by genitalic morphology (see McGuffin,1987).

Life History
The larvae, described in detail by McGuffin (1987), are light brown with brown lines and mimic twigs in colour, posture and shape. Pupae hibernate.
Conservation
Not of concern.
Diet Info
Reported larval hosts that occur in Alberta include chokecherry (Prunus virginiana) (Ferguson 1954).
Range
Southern interior BC east to Nova Scotia and south to FL and TX (McGuffin 1987).
