Ok. So I've been seeing observations of these guys on iNat down in SoCAl for the last month now. This has made me want to see one. Well I finally did. I was trying to get some pics of a cabbage white when all of a sudden a huge thing flies right in front of me. At first I thought it was a hummingbird because of how big it was but nope it was a white-lined sphinx. Sorry for the not so clear picture. It was the only one I got of it because he would not stay still. But believe me this was it.
