Alabama Butterfly Atlas

Butterfly: Wingspan: 2 1/8 to 2 3/4" (5.4-7.0 cm). Upper surface of males is lemon yellow with no markings. Female may be yellow or white; outer edges of both wings have irregular, patchy black borders; the upper forewing has a dark spot. Lower surface of hindwing of both sexes has 2 pink-edged silver spots.

ID Tip: Large yellow wings with no solid black wing edges

Egg: Spindle-shaped eggs first white, then quickly turn orange.  They are laid singly on host leaves or flower buds.

Caterpillar: Color is variable: may be green with a bright yellow stripe; green with a bright yellow stripe and blue patches on the sides; yellow with bright yellow line on sides;  yellow with bright yellow line on sides and black rings. All have varying degrees of short hairs that come from tiny black tubercles.

Chrysalis: Green, yellow or rosy in color. Greatly compressed from side to side.  Resembles a leaf. 

The Cloudless Sulphur is one of the most common and conspicuous butterfly species in Alabama.  It flies from border to border throughout the spring and summer months. Autumn populations rise to astonishing numbers as northern migrants join local populations.  During fall, southbound individuals are common sights along interstate highways and other roads, covering as many as twelve miles per day.  

Cloudless Sulphurs have an exceptionally long proboscis (mouthpart) which allows them to access nectar from the same long-tubed plants that feed hummingbirds. 

 

Distribution and Abundance

A dot on the county map indicates that there is at least one documented record of the species within that county. In some cases, a species may be common throughout the county, in others it may be found in only a specific habitat.

The sightings bar graphs depict the timing of flight(s) within each of three geographic regions. Place your cursor on a bar within the graph to see the number of individuals recorded during that period.

The abundance calendar displays the total number of individuals recorded within each week of the month. Both the graphs and the calendar are on based data collection that began in 2000.

The records analyzed here are only a beginning. As more data is collected, these maps and graphs will paint a more accurate picture of distribution and abundance in Alabama. Submit your sightings to albutterflyatlas@gmail.com.

Landscaping Ideas

Plant Partridge Pea (Chamaecrista fasciculata) to support many sulphurs, including Cloudless Sulphurs. 

Since Cloudless Sulphurs have an exceptionally long proboscis (mouthpart) they can access nectar from the same long-tubed plants that feed hummingbirds.  Native azaleas (Rhododendron spp.), Trumpet Honeysuckle (Lonicera sempervirens), Cardinal Flower (Lobelia cardinalis), and Scarlet Sage (Salvia coccinea) are among the nectar plants that will add beauty to your landscape as well as feed Cloudless Sulphur butterflies and Ruby Throated Hummingbirds.
