Still learning

Over half a century ago, I was a teenager and I started to learn the names of the local butterflies. I had a poor ability for carrying what I learnt from summer to summer since I was cramming my brain with all manner of other things in between.

Eventually i forgot almost all of them. And, thus, in my retirement, my dotage, I've been trying again to learn them.

I was sitting in the somewhat cool shade underneath our deck this afternoon when this fellow landed nearby. It may be the most common one in our backyard. I call it the Yellow swallowtail but I know (now) that it is officially something like the Canadian tiger swallowtail.

Or so I think anyway.
