3 August 2000 12:38AM EST (bottom right) The bottom
left and bottom center photographs are of the same individual. Schizura
badia is one of about half a dozen species of Schizura that may occur
in my general area, most of which are illustrated on this web site.
Covell (1984) has termed this the Chestnut Schizura, presumably because
of the warm chestnut-colored areas on the forewing. Overall, I would
describe the ground color of the forewing as yellowish tan, lighter and
grayer toward the costa. The reniform spot is marked by a curved black
line with a blackish shade beyond, which extends and widens toward the outer
margin. There is a white patch at the apex. In the basal area
and in the terminal area towards the anal angle, there are areas of reddish
chestnut brown. Covell describes the hind wing as dark brownish, but
in the photo at top right, the hind wing looks to be yellowish tan shaded
with brown toward the outer margin.
At rest, Schizura badia usually holds its wings in a
"tent" position, sometimes partly rolled
around its body.
The larvae of Schizura badia feed on viburnum species; Covell
(1984) specifically mentions "northern wild-raisin", while
Handfield (1999) notes Viburnum cassinoides. According to
Handfield, the flight season in my general area is from late June to about
the end of July.
I have photographed this species in 2000 on 14 July and 3 August; in
2001, on 18, 21, 22 and 23 July; in 2002, on 19, 22, 15 and 29 June, and on
3, 20, 27 and 31 July. |
