Parapoynx allionealis is one of four species of Parapoynx
recorded from the Ottawa area (J.D. Lafontaine, pers. comm., 2001), all of which
are illustrated on this web site. My initial identification of Parapoynx
allionealis was based on Munroe, E., The Moths of North America North of
Mexico, Fascicle 13.1, Pyraloidea Pyralidae (Part) (London: E.W. Classey,
1972-1974) and specimens in the Canadian National Collection in Ottawa.
From the descriptions of Munroe, it is likely that the specimens illustrated
above are all of the subspecies Parapoynx allionealis itealis, which
occurs in northeastern North America.
Parapoynx allionealis itealis exhibits sexual
dimorphism, the male being moderately patterned, whereas the female is much
paler, with markings that are faint to absent.
The forewing of the male Parapoynx allionealis itealis is generally
whitish, variably overlaid with brown, and with markings that are variably
distinct. Dark spots consistently present in the center of the forewing at
about 1/3 and 2/3 the length of the wing; the hindwing has one dark spot, at
about the center of the wing. Both forewing and hindwing are crossed by
lines and bands. clearest towards the outer end of the wing, becoming less
distinct towards the basal end. Beginning at the outer margin, the
following lines are generally visible: a yellow-brown line along the outer
margin, sometimes with a row of dark dots immediately preceding the fringe; a
dark brown to black line that is mostly smooth on the forewing, somewhat
scalloped on the hindwing; a wider yellow-brown line, generally edged with dark
brown on either side; a dark gray-brown line of variable thickness, usually
including or near the inner dark spot on the wing. Even when the wings
have a heavier brown overlay, as in the left photo in the third row, these lines
can generally be distinguished, especially on the hindwing.
The female Parapoynx allionealis itealis is generally
very pale to immaculate white. Traces of
pattern similar to that of the male may be faintly present on the wings, and the
dark spots seen on the wings of the male are also present, though they may be
pale gray and inconspicuous.
According to Munroe (1972), the host plant for Parapoynx
allionealis itealis is not certainly known, but studies suggest the larvae feed on
floating pondweed.
