Its spring and our backyard is alive with birds, squirrels, chipmunks, garter snakes, and a few butterflies.

I think I managed to identify this correctly as an Eastern Tiger Swallowtail. It rested for a moment on a tree and I was able to get this almost complete shot.


The Eastern Tiger Swallowtail (Papilio glaucus) is a species of swallowtail butterfly native to North America. It is one of the most familiar butterflies in the eastern United States,[2] where it is common in many different habitats. It flies from spring to fall, during which it produces two to three broods. Adults feed on the nectar of many species of flowers, mostly from those of the Apocynaceae, Asteraceae, and Fabaceae families. P. glaucus has a wingspan measuring 7.9 to 14 centimeters (3 to 5.5 in). The male is yellow with four black "tiger stripes" on each fore wing. Females may be either yellow or black, making them dimorphic. The yellow morph is similar to the male, but with a conspicuous band of blue spots along the hindwind, while the dark morph is almost completely black.

The green eggs are laid singly on plants of the Magnoliaceae and Rosaceae families. Young caterpillars are brown and white; older ones are green with two black, yellow, and blue eyespots on the thorax. The caterpillar will turn brown prior to pupating. It will reach a length of 5.5 centimeters (2.2 in). The chrysalis varies from a whitish color to dark brown. Hibernation occurs in this stage in locations with cold winter months.

Hi Alan,
you have captured a beautiful butterfly, it look similar to our macaon.
Pretty good sharpness, nice composition.
Maybe the butterfly is a bit to yellow,I could be wrong since I never seen one in reality.
Nevertheless it's a fine picture.
Well done,

  • Great

Hi Alan
Great Eastern Tiger Swallowtail of this spring,no?
Lovely details and colours!

Maybe a little hurried shot, considering your apprehension of it flying away if you did not act promptly. Alan. Keeps on happening with me quite often while shooting particularly restless species of butterflies like Swallowtails.
Still, the shot is very good in terms of colors and patterns on the wings.
