10 May 2003 (specimen captured 8 May 2003) (bottom right) The
photos at top left and bottom right are of the same specimen. My
thanks to Dr. J. Donald Lafontaine of Agriculture Canada for identifying the
actual specimen pictured at bottom left, thereby enabling me to recognize
the other specimens. Since published photographs of many dark-colored
moth species often do not show enough detail to enable a certain
identification, and since my own photographs sometimes present the same
problems, it has proven worthwhile in many situations to capture the moth
for a closer examination and additional photographs. Homoglaea
hircina, also known as the Goat Sallow, is a very dark gray-brown in
color. Covell (1983) notes that it has a very hairy body, and this is
evident in the photo at top right. The antemedial and postmedial lines
are double, filled with a paler gray-brown. The reniform and orbicular
spots are not always obvious, but may be at least partially outlined in the
same pale gray-brown as the am and pm lines. The medial line is
indistinct, but a darker line across the median can be seen in the bottom
right photo. The subterminal line appears somewhat paler, marked by
dark dots. The hindwing is a lighter gray-brown than the forewing. The
larvae of Homoglaea hircina feed primarily on poplar. According
to Handfield (1999), this moth hibernates as an adult, with flight seasons
in my general area from about mid-April to mid-May, and from late September
to the beginning of November. I have photographed this species in
2003, on 19 and 20(22) April, and on 8(10) May. |
