On August 17th, Jane and I searched five patches of Prickly Ash on a ten acre property near Belmont Lake, and saw a combined total of more than 80 larvae of Giant Swallowtail, (representing all five instars), plus an additional five eggs at one of the sites. I would expect that many will attempt to over-winter as pupae, and I believe that as a species, they are here to stay. I see them, (adults), pretty much daily now, in my travels between Havelock, and Stoney Lake, and have been since mid-July. We had a couple around also, in late May of this year.
