The Butterflies of Canada says &quot;They occasionally overwinter
successfully in Canada in mild winters.&quot; Howe's Butterflies of North
America says that in the USA adults normally hibernate only from
Pennsylvania south, so in most &quot;normal&quot; years (at least those
before climate-change began to accelerate) worn adults in NS would have
flown north from at least the latitude of Pennsylvania.<br><br>
Scott's Butterflies of North America refers to a tagging study on a
hilltop location in California. Of individuals tagged, 93% were gone
within 24 hours. The maximum stay was only 3 days. All this indicates
their great powers of mobility. When they are on the move, they can
really move. :-&gt;<br><br>
