Perhaps the recent tornados and strong windstorms, or extreme heat further south, have encouraged a migration or allowed for great displacement.
There is also a possibility of a pupa being unwittingly imported in soil of a purchased plant from further south.
Bonnie writes, "I am curious to know if it is breeding here, or if it has blown in as some migrating birds do who are blown off course (we are on a major spring bird migration route)."
I (Bill Oehlke) reply, I do not think there are breeding populations north of the extreme southern US states. Wind assistance would be my first guess at an explanation.
