Calledapteryx dryopterata, also known as the Brown Scoopwing, is one of two species occurring in the Ottawa area that belong to the Epiplemidae family of moths, which has now been reclassified as a subfamily of Uraniidae.

Calledapteryx dryopterata has brown wings, often slightly reddish in color.  The median of the forewing is defined by dark brown lines in the upper part of the wing, with some brown shading between them; these lines face out in the lower half of the wing, but there is a dark brown semi-circle at the midpoint of the inner margin.  The upper half of the outer margin of the forewing is deeply scooped out, edged with dark brown.  The hindwing is crossed by two darker lines, but without significant shading in the median.  The outer margin of the hindwing has several irregular inward scallops, giving it a somewhat ragged appearance.  The wingspan ranges from 1.8 to 2.2 cm (Covell, 1984).

According to Handfield (1999), the larvae of Calledapteryx dryopterata have been reported to feed on two species of viburnum that do not occur in my area or in the areas where this species has been collected in Quebec.  It is possible, therefore, that another species of viburnum serves as host plant at my location. For my general area, Handfield indicates an adult flight season from early June to slightly after mid-August.

My records to date for Calledapteryx dryopterata (each date representing "the night of") are in the table below:
