Sphecodina abbottii, or Abbott's Sphinx, has a dark
brown forewing with a lighter brown to tan median. In some lighting
conditions, the dark brown may have a grayish cast, as in the photo at bottom
left. The outer edge of the medial area swoops outward towards the middle
of the outer margin with bands of tan and dark brown, then forms deep narrow
zigzags to the costa, giving a somewhat streaky appearance to the wing.
The outer margin is somewhat scalloped, and there is sometimes a clearly defined
gray-brown apical patch. The hindwing is yellow, bordered in dark brown;
stripes at the inner margin of the brown border align with the banding of the
forewing when the wings are partly closed. The thorax and abdomen are
banded in dark purplish gray, black and brown. The antennae are
yellow. Covell (1984) indicates a wingspan of 5.7 to 7.0 cm.
According to Handfield (1999), the larva of Sphecodina
abbottii has been reported to feed on ampelopsis, grape, Virginia creeper
and hawthorn. For my general area, he gives an adult flight season from
about mid-May to late June.
My records to date for Sphecodina abbottii (each date
representing "the night of") are in the table below:
