Almost surreal in it irredescence, this agehachou is one of the many stunning butterflies we’ve encountered on our Hokkaido bike trek.

We’re not lepidopterists, but it would be all but impossible not to notice the incredible beauty and diversity of the moths and butterflies – not to mention the amazing variety of caterpillars – we’ve been encountering on our bike trek around Hokkaido, Japan. If you find them early enough in the morning when they’re still warming up, you can sometimes sneak a decent photo. This agehachou (Asian swallowtail) is among the more stunning butterflies we’ve found, but it seems that all butterflies are beautiful. As the summer progresses and flowers change, different species are emerging. Today the paths were filled with nearly iridescent black caterpillars, leaving us wondering what form they’ll take as adults.
