Confused Cloudywing
Thorybes confusis
Perhaps.
"Called Confused Cloudywing
for good reason, the identification of this essentially southern
butterfly is extremely tricky, and many individuals cannot be
identified in the field. Spot pattern above varies from usually
very restricted (like the Northern Cloudywing) to extensive (like
Southern Cloudywing)" (Glassberg, p. 152)
"Middle spot of lower group
of three spots usually a pale thin line (if present at all) ...
[they] lack the white patch at the bend in antenna club."
(Glassberg, plate 49.)
