scripta is one of two very similar species of Habrosyne known to
occur in Ottawa (J.D. Lafontaine, pers. comm., 2001).
of Habrosyne scripta is brownish gray, strikingly patterned in white
and black with shading in reddish brown, and a very sleek, smooth
appearance. When the wings are closed in the resting position, the
gray-brown lower part of the basal area is so smooth and plain as to remind
one of an empty cartouche where one would have the monogram engraved on a
piece of ornate silver. The postmedial line appears as a looping
zigzag of fine black parallel lines, clearest at the midpoint of the
wing. The thorax is surmounted by a very architectural crest or ruff;
the bottom right photograph gives some sense of the three-dimensional
complexity of this feature. Covell (1983) indicates a wingspan of 3.0
to 3.9 cm.
The larvae of Habrosyne scripta
feed on various species of birch and on Rubus species such as black
raspberry, purple-flowering raspberry, etc. (Handfield, 1999).
Handfield indicates two generations per year for this species in my general
area, with flight seasons from late May to the beginning of July, and from
early July to the end of August.
I have recorded this species in
2001 on 18 and 26 June, and on 8 July; in 2002, on 30 June; in 2003, on 7
July; in 2004, on 23 May, on 17 June, and on 12 July.
