Over the past four weeks I have reported several sightings of Monarch butterflies winging their way westward over the ramp here at University Park Airport (SCE) in State College, PA.   In each case, it has been only one butterfly per day.   However, today set a new "record" (for this year) with four butterflies spotted over the course of the day.

Here are their stories:
