Schizura leptinoides 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) calls Schizura leptinoides the Black-Blotched
Schizura, in view of its reniform spot, which is black followed by a
blackish shade. Overall, the forewing is medium to dark gray, somewhat
lighter and tinged with brown towards the inner margin. The antemedial
and postmedial lines are double and somewhat indistinct. There is a
prominent squarish light gray-white patch at the apex. What can be
seen of the hind wing in the first two photos above is a somewhat dirty
white color. Covell notes that the female has a dark gray hind wing.
At rest, Schizura leptinoides often holds its wings in a
"tent" position, sometimes partly rolled around its body.
Occasionally, however, it may hold its wings in a more flattened position as
in the top two photos.
The larvae of Schizura leptinoides feed on a variety of deciduous
trees and shrubs, including apple, beech, birch, oak, poplar, butternut and
other species. According to Handfield (1999), the flight season in my general
area is from early June to late July, although he mentions one occurrence in
mid-August. My own experience with this species has been quite
different, with the majority of my observations to date in August.
I have photographed this species in 2000 on 22 August; in 2001, on 16
June; in 2002, on 8 June, on 24 July, and on 4, 5, 10 and 22 August. |
