Observation notes: On my way home from a medical appointment, at about 10:50 AM (EDT), I stopped by the Wildlife Restoration portion of Pennsylvania State Game Lands #333 on the east side of Shiloh Road, near I-99 east of State College, PA. I do this occasionally to look for Monarch Butterflies to report to the Journey North web site. Today there were numerous small white and yellow butterflies fluttering about. But what caught my eye in the distance was an Eastern Tiger Swallowtail (Papilio glaucus) nectaring among the thistle. At the time, the air pressure was 28.68 inches and beginning to drop, the air temperature was 73°F and rising, the dew point was 68°F, the humidity was 83% and beginning to drop, with no wind under fair skies.
