|scientific name Olethreutes punctana |
Brushy or wooded areas with Red Osier Dogwood (Cornus stolonifera) and Chokecherry (Prunus virginiana).
Alberta material has been collected from June 20 to July 27.
A Tortricid moth of the subfamily Olethreutinae and tribe Olethreutini. Formerly in the genus Exartema along with the related species inornatana and quadrifidus but now in the large genus Olethreutes. These three species all have wings that are olivaceous brown in color with somewhat darker apical and mid costal patches, wingspans in the 16-20 mm range, fly at the same time and have similar food plants. The fore wings of punctana have a dark basal patch as well as a dark discal spot, while the other two species lack these features. Like inornatana, the male genitalia have a digitus projecting from the neck of the harpe near the sacculus, whereas quadrifidus has a digitus near the cucullus. The male genitalia are illustrated in both Heinrich (1926) and Miller (1987). Alberta material does not match O. connectus, described by McDunnough (1935) from Ontario, even though some regard the two as synonymous.
Comes to light.
Apparently not widespread, but probably of no concern.
Cornus (Heinrich 1926), of which it is a leaf tier.
New York, New Jersey, Massachusetts, New Hampshire, Ontario, Quebec and California (Heinrich 1926). McDunnough (1935) cites material from British Columbia. Miller (1987) reports it from Michigan and Wisconsin. It is also known from Quebec and Labrador (Handfield 1997). In Alberta, it is known from the Edmonton area.
