Lacanobia subjuncta is one of four species of Lacanobia
recorded from the Ottawa area (J.D. Lafontaine, pers. comm., 2001), two of which
are illustrated on this website. My thanks to Mr. J.T. Troubridge of Agriculture Canada for confirming my identification of the bottom specimen illustrated above.
The forewing of Lacanobia subjuncta has a purplish gray
ground color, shaded with reddish brown. The upper half of the basal area
is light reddish brown above a black basal dash. The double, scalloped
antemedial and postmedial lines are filled with the ground color of the wing,
and typically most clearly marked in the lower half of the wing towards the
inner margin. The claviform spot appears as a somewhat darker loop
extending outward from the am line; a black dash runs from its outer end to the
pm line. The orbicular and reniform spots are outlined in black and filled
with dull gray-brown, with near black filling in the lower end of the reniform
spot. The area between the pm line and the whitish subterminal line is
often somewhat paler than the rest of the wing, but not so much as to present a
sharp visual contrast. The st line angles sharply outward to form two
points extending to the middle of the outer margin, in a shape resembling a
W. The hindwing is dirty yellowish gray in color, with some darker shading
towards the outer margin. Covell (1984) indicates a wingspan ranging from
3.4 to 5.0 for this species.
The larva of Lacanobia subjuncta is known as the Speckled
Cutworm. According to Handfield (1999), the varied host plants reported for Lacanobia
subjuncta include alder, willow, various plants in the cabbage family,
blueberry, maple, asparagus, strawberry, corn, viola, potato, dandelion,
poplar and meadow-rue. For my general area, he indicates two
generations per year, with adult flight seasons from late May into early July
and from near mid-July into early September.
