Today’s special visitor was a very big Black Form Female Tiger Swallowtail butterfly. We posted some pics on Facebook. I commented that there’s a good chance that she came from Virginia’s Briar Patch Habitat, just one mile from our native plants garden. Came to partake of our Bottlebrush Buckeye bush, now in splendid full bloom. It may well be that the super fresh Giant Swallowtail also flew to us from the Briar Patch.
Virginia C Linch posted a Comment to my Facebook post, and it got me to thinking.
If butterflies are especially attuned to aromatic emissions from active flowers, what is the working range that their sensory organs can effectively track? In other words, did our 2 extraordinary butterflies follow aromatics from our 303 Garden to the vicinity of the Briar Patch Garden? Is that how they came to visit us, following a trail of aromatic hydrocarbons? Curt, Phil, Virginia, Ken, Bob, NABA friends, Holli, Rose, Nancy and John, Dave, Dave W, Bill, Deepthi?
The accompanying photo? Me at the Habitat, working to score a Skipper image.
