The top and center left images
are of the same individual; the center right image is of a second specimen
present at the same time.
Live specimens of Hyperaeschra georgica
may be seen at rest with its wings held close
to the body in the shape of a peaked roof (center right), or in a more
flattened position (center left). Covell (1984) describes the forewing as
yellowish with gray overlay and black streaks; thanks to the streaks and the
zig-zags of the antemedial and postmedial lines, I see it as a bit of a
patchwork pattern. The am and pm lines are accented with white on the
side away from the medial area. The specimens I have photographed are
generally consistent in having a very noticeably lighter-colored
"patch" on the forewing in the center of the basal area inside a
large zig in the am line, still noticeable even in darker specimens (bottom
photo). When the moth spreads its wings, you can clearly see a black
tuft projecting from halfway along the inner margin of the forewing
(top). When the moth rests in a "tent" position, the tufts
project upwards from the peak; you can see the shadow of the tufts in the
center right photo.
The larvae of Hyperaeschra georgica generally feed on oak,
especially red oak. In my general area, according to Handfield (1999), the
adult may be observed from late May to late July.
I have photographed this species in 2002 on 2, 5, 9, 11, 19, 20 and 25 June.
