Most of us have heard of butterfly epithet "frittilary".
I found "frittle" in a word site;
frittle
(fritt'-ul) n. a temporary mark on the skin caused by the impression of a textured surface. [prob. inspired by the similar close patterning on the flower or butterfly called Frittilary, for its checkered markings, from Latin fritillus "a chess/checker board"].

Other sites reate it to dice box.

I'm having trouble with Yahoo giving me "Page not Fount"
even to AHD. Badword yahoo. Anybody else want to comment
on "frittle"?
