Spring is for the Butterflies

Catch them this year along the Parkway

by Clyde Kessler

From mid to late March through October, and sometimes into a mild winter, butterflies flourish along the Parkway.  I have observed around 90 species from milepost 0 at Afton Mountain to milepost 469.

Harbingers of spring include the Silvery Blue, Spring Azure and Falcate Orangetip.  All three of these are dazzlers, flying flowers after winter.  The Spring Azure can be found along most of the Parkway, while I have only found the Silvery Blue in a few places north of Roanoke so far.First Place Adult Division 2007 Photo Contest

The Falcate Orangetip flies in April at low to mid elevations (less than 3,400 ft.), and I have had the joy of seeing it in many locations from Humpback Rocks to Asheville.  Getting a photograph of it is another story, as these butterflies always seem to be on the move, seldom stopping to nectar on flowers.

The Parkway sees six species in the swallowtail group of butterflies, though one (the Giant Swallowtail) is scarce: Pipevine, Zebra, Black, Giant, Eastern Tiger and Spicebush.  I have only seen the Zebra Swallowtail in the Virginia section of the Parkway, and it is common only near the James River.  A few friends of mine have a couple of records near Boone and near Asheville.

Other groups of butterflies visible along the Parkway:  whites and sulphurs (nine species), gossamer wings, coppers, hairstreaks, blues (16) species), brushfoots (29 species) and skippers (30 species).

I often start early in the morning watching and listening to birds, then as the day warms up I start looking for butterflies, seeking out places with lots of flowers.  The sunnier the day, and the more sheltered from the wind that the meadow or woods edge is, generally the more butterflies I find.

I offer the following advice to make your butterfly watching more fun:

• Dress comfortably to match the weather
• Wear a hat if you will be in the sunlight for a long time
• Put on sun screen and insect and tick repellent

I also take along snacks, a lunch and plenty of water.  I usually have with me a couple of identification guides, and some notebooks for recording butterfly behaviors, numbers seen, locations and what flowers seem to attract them.
