Lack of butterflies

Liz is correct.  For many years there was an *assumption* that 
Viceroys were Batesian mimics of the Monarchs, good-tasting beasts 
looking like the nasty-tasting Monarchs.  However, when the tests 
were actually done (does anyone have the reference for this paper?), 
Viceroys turned out to be nasty, too.  The infamous Mullerian mimicry 
at work . . .
