RARE AND UNUSUAL BUTTERFLY



ORIGINAL LABELS


"The above images are of the original type specimen of Strecker's hybrid "rubidus" from the
Field Museum of Natural History (FMNH) in Chicago. The type specimen fixes the phenotype associated
with Strecker's published name(1878). Although this name has no official standing
according to the rules of the International Committee of Zoological Nomeclature (ICZN),
this is the essence of "rubidus."

I am convinced that Strecker is the sole author of the name and his single specimen from Reading, PA, is the type.
Note the "rubidus" type has no white banding on dorsal or ventral forewing,
leaving no doubt whatsoever this is a Red-Spotted Purple x Viceroy hybrid.
Thanks to Dr. Margaret Thayer and James Boone of FMNH for supplying photos from the Strecker Collection."
