  • CAPTION PAGE/Chip: Butterflies bottled up/Only seen this behavior once in the springtime. More details later. On Apr 4, 2017, at 8:34 PM, Taylor Jr, Orley R: In all the records of first sightings over the last decade and more, have you ever received a report of spring clustering that involves hundreds, perhaps thousands of monarchs? Years ago, I watched a small cluster of 10-12 form on some pine trees at the top of a hill in a pioneer cemetery. Most appeared to be males.
