Mr. Henry Edwards speaking of Chalcedon says: — “The perfect insect appears 
to be generally distributed throughout the State, extending also into Oregon and 
Nevada.. The first individuals make their appearance about the second week in 
April and successive broods are hatched up to middle of July. The caterpillar 
feeds upon Scrophularia chiefly, though I have observed it upon Dipsacus, Castil- 
leja and Lonicera. It is one of the most abundant of our species, every canon lead- 
ing from the mountain chains to the valley below being productive of large num- 
bers. It is an active insect, seldom remaining settled in one place and is very 
pugnacious, driving away every other butterfly which may venture near it. On 
this account it is very troublesome to the collector and I have lost several rare 
insects entirely through this habit of Chalcedon. Like all Melitseas, it is subject 
to considerable variation, in some individuals the reddish patches covering nearly 
the whole of the upper surface of the primaries. The female is far less common 
than the male, is inactive and flies but little.”
