Where and When

Look in almost any park or public garden with flowers, which means mostly in the summer. You may start to notice that some flowers are popular with many species, while some species seem to specialize. You will be rewarded when you visit the same area one or two weeks later.


If you plan to wade through deep grass, beware of ticks. At a minimum, tuck your pants into to your socks.

Much of the time, you can get a good photo of a butterfly when it is feeding on a blossom with a mobile phone’s camera. Of course, you can get more and better photos with fancier camera gear.
