Feltia jaculifera, the Dingy Cutworm Moth, is one of
three species of Feltia occurring in the Ottawa area; a fourth species, Feltia
subgothica, was formerly recorded from Ottawa, but the very similar Feltia
tricosa (Hodges 10675) seems now to have extended its range and become the
more prevalent species in our area (J. D. Lafontaine, pers. comm., 2001;
Handfield, 1999).
Covell (1984) describes the forewing of Feltia jaculifera
as being of a dirty whitish color with gray and blackish shading. When I
look at it, however, the inverse description comes to mind: a
predominantly black forewing, frosted with white, gray and tan streaks and
shades. Two sets of streaks extend from a point at the
base outward to skim the upper and lower ends of the reniform spot. The
uppermost streak, closer to the costa, terminates at the costa shortly before
the apex; the lower streak branches before reaching the lower end of the
reniform spot, with the lower branch meeting a pale gray and brown streak that
extends along the inner margin from base to anal angle. At the lower end
of the reniform spot, there are usually two highly visible double streaks that
stop just short of the outer margin a short distance above the anal angle.
The orbicular spot is represented as a rounded triangle extending down from the
pale costal streak. The reniform spot is pale beige to brown with a paler
outline. The curved postmedial line is often followed by pale streaks or
shading, with patches of black along the outer margin. There is also a
dark patch in the subterminal area near the apex of the forewing. The
hindwing is whitish, with some gray-brown shading, a dark terminal line and pale
fringe. The thorax and tegulae are various shades of gray-brown, with the
tegulae usually paler and appearing whitish in some lighting conditions.
Covell (1984) indicates a wingspan ranging from 3 to 4 cm.
Feltia jaculifera has some similarities to other Feltia
species occurring at my location, but overall exhibits a more delicate and
complex pattern with high contrast and clear boundaries between most of the dark
and light areas. When I first encountered this genus, I found it very
confusing to differentiate the three species. Now that I am more familiar
with these moths, I look first for the clear double prong springing outward from
the lower end of the reniform spot in Feltia jaculifera, for the pale
merged streak extending along the inner margin right through the postmedial line
to the anal angle in Feltia tricosa (Hodges 10675), and for an abrupt end
to the prominent pale streak at the postmedial line in Feltia herilis
(Hodges 10676)
According to Handfield (1999), the larva of Feltia jaculifera,
the Dingy Cutworm, feeds on plants cultivated in market gardens, tobacco,
bluegrass, cereal rye, and other crops, as well as a variety of non-cultivated
plants. He indicates an adult flight season from
the the second week of July into early September for my general area.
