A few days after that, Kirsty retweeted this from Justin Berk:
Lots of Butterflies! RT @JustinWeather: Have you noticed more butterflies than normal? Some see these as signs of a cold/snowy winter ahead.Cool, I'm not alone in noticing this. Still, I'm just wondering why are there so many butterflies? And do they really signal a cold or snowy winter?

The Farmer's Almanac is often referenced when people predict seasonal forecasts. Their list of 20 Signs of a Hard Winter mentions early Monarch butterfly migration, but those guys aren't yellow. (By the way, if you want to track Monarch migration, go here.) What we had here was a bunch of swallowtails.
Can you see 'em?
|This Joe Pye Weed has at least five butterflies on it.|
Some time searching the Internet (with frequent trips to Google to change the search terms) led me to conclude we've noticed a mass hatching, otherwise known as an irruption, coinciding with the recent blooming of Joe Pye Weed.
I don't know if this flutter of swallowtails is a sign of cold or snowy winter, but if it is, it sure is a pretty one. Pigs gathering sticks, on the other hand....that's just funny.
