I noticed this guy flitting about this afternoon and got a smile watching him (Black Swallowtail, male). He was perched in the top of one of my autumn olive bushes (yes, I know, but they smell soooo good in spring!); and he was so territorial, he was chasing everything that moved. He chased off a Spicebush Swallowtail and a Red Admiral; he was even chasing birds! There's a family of mockingbirds in a nearby pine branch and the parents are busily bringing in food for the babies, and every few minutes when one would fly over, he'd leave his perch and follow it for a good 15 feet before returning to his post. Such a brave little guy!
