Despite the inevitable heat and humidity, August has its rewards. Here, an Eastern Tiger Swallowtail ( (Papilio glaucus) visits Sweet Pepperbush, or Summersweet (Clethra alnifolia): a deciduous shrub native to swampy woodlands, wet marshes, and stream banks.
Although found along the coast from Maine to Florida, and west into Texas, Summersweet’s native presence here is limited to a few counties in the area of the Big Thicket, where this photo was taken.
At first, I assumed I’d found a Black Swallowtail visiting the flowers, but I soon learned those butterflies have yellow spots on their bodies, while Tiger Swallowtails exhibit yellow streaks along each side of the thorax and abdomen. The existence of dark morphs like this one among the Tigers can make things even more confusing, but the sight of one is immensely enjoyable.
