Although butterflies are around in the spring and fall, to me butterflies mean summertime. In my part of the state, there are two different types of tiger swallowtail butterflies and when they are flying, it is hard to look at the spots to know which type it is. Normally the ones I capture with a photo are the Eastern Tiger Swallowtail, but sometimes the Canadian Tiger Swallowtail will adventure into camera range.
