My identification of
this moth was initially based on Hodges, R.W., The Moths of North America
North of Mexico, Fascicle 6.2, Gelechioidea Oecophoridae (London: E.W.
Classey, 1974). My thanks to Dr. Jean-François Landry of Agriculture
Canada, who subsequently agreed with this identification for two specimens I
collected for the Canadian National Collection.
inornata is unquestionably the plainest of the five species of Semioscopis
known to occur in the Ottawa area. Hodges notes that it can be
separated from the other species by the slightly blue-gray cast of the
forewing, and the eight specimens I have photographed at my location have
all exhibited this coloration, although it has not always been evident in my
photographs, depending on the lighting conditions. In addition, Hodges
notes the presence of a pair of black dots at half the length of the cell in
many specimens, a feature that is marginally evident in both the photos
above. He also notes that some specimens exhibit a very faint curved
line at the end of the cell, but this has been absent from most of the
specimens I have photographed. The wing length of this species ranges
from 10.5 to 15 mm.
Hodges indicates that larvae of S. inornata
have been reared on several species of poplar and willow. The adult
moth flies in the spring.
I have photographed this species in 2002, on
6 May; in 2003, on 21 April and on 4, 5 and 9 May.
