When I took this photograph I had dismissed it as a Monarch but after looking at my other shots of Monarchs I don't know what this one is.

Papilio polxenes
Why really common some years - hard to say, but probably a combination of favorable weather over a period of time, and a scarcity of parasites. Most species tend to become really abundant periodically only to abrubtly drop back down in numbers again until the next time things become really good for them.

Moved from Butterflies.

Dill Plants
Well these shots where taken at a local park, so I don't mind at all But this image was taken last year, which could explain why we've got many nice looking Black Swallowtails around this year :)
