moths

Southern Pearly Eye

The Southern Pearly Eye (Lethe portlandia) has a wingspan of 2¼ – 2¾ inches. The antennal club (the tip and thickest part of the antenna) is orange. As caterpillars, they are green or brown with thin, light stripes, two short tails, and two reddish horns on green heads. As chrysalis (pupa) they are little green pendants that often dangle from a host plant stem. Their host plants are Canes (Arundenaria spp.). They are most active on cloudy days and at dusk.
Cool Fact: Cocoons and chrysalis are often used interchangeably when discussing moths and butterflies, but they are two completely different things! Moths form cocoons, whereas butterflies form chrysalis.

Webworm Moth

– Webworm Moth –
The Ailanthus Webworm (Atteva aurea) adults are considered good pollinators. The host plant, Tree of Heaven (Ailanthus altissima) is a non-native plant in Florida that the Ailanthus Webworm will use for laying eggs. Caterpillars will emerge and feed on the leaves. This species also use two native Florida plants. Both are Paradise Trees, Simarouba glauca, and Simarouba amara.

Luna Moth

Luna Moth
The adult Luna moth, Actias luna (Linnaeus), can be found every month of the year in Florida’s forests. They range from southern Canada to Florida and as far west as Texas. This large green moth has a wing span of 3–4¼ inches.
The luna moth lays eggs, and the caterpillars are bright green. Host plants include sweet gum, sumacs, hickories, persimmon, and plants in the walnut family. The adult moth cannot eat and only lives long enough to mate, and lay eggs. You will be lucky if you encounter one of these beautiful moths while sauntering through the woods.
Fun Fact: The Luna moth appeared on a first-class United States postage stamp issued in 1987.

Gaudy Sphinx

The Gaudy sphinx, Eumorpha labruscae, is a common and vibrant green moth whose range is from Argentina to Canada. Host plants include muscadine grapes, Christmas bush, and other vines. Pupae climb down into the soil where metamorphosis takes place. They emerge as adults. Females release pheromones at night to attract males who follow the scent.

Scarlet-bodied Wasp Moth

The Scarlet-bodied wasp moth, Cosmosoma myrodora, is a stunning moth found throughout Florida and coastal areas in the southeastern U.S. Males have filament containing pouches on the abdomen called flocculence. During mating the male will hover over the female and discharge the flocculence, creating a net over her before attempting to mate. These flocculence’s are a visible white.
The larvae emerge from the eggs appearing as tiny white hair-covered caterpillars. These hairs are called setae and help form the cocoon. Cocoons are constructed under leaves and are mesh-like balls. Larvae feed on native hempvines.
Adult males feed on dogfennel and pass the toxin, pyrrolizidine alkaloids, obtained from the plant to females during courtship as a way to protect eggs from predation. Some parasites are still able to get past these defenses. These include Hyphantrophaga sellersi and Tetrastichinae parasitoids.

Polyphemus Moth

The Polyphemus moth, Antheraea polyphemus, is a giant silk moth that can be found from Mexico to southern Canada and in every US state except Nevada and Arizona. The moth’s wingspan measures 4 – 6 inches. Colors vary and include gray, tan, and brown with shades of red, yellow, and pink. Polyphemus moths have large eyespots on their hind wings and were named after Polyphemus, the giant cyclops from Greek mythology with a large eye in the middle of his forehead. The male’s (pink pictured) antennae are bushier than the female’s (tan pictured) antennae.
 
Females produce 2 broods each year. In Florida, newly emerged Polyphemus moths can be found year-round. Because of their vestigial mouthparts, they cannot eat. A newly emerged female will release a pheromone to attract a male. The dating game lasts throughout the night with the most activity a few hours before sunrise. The pair will remain coupled all day before separating at sunset. For the next several nights, the female will lay single eggs in groups of two or three on a leaf of an oak tree or other desirable host tree.
 
Look for these moths near man-made light sources. Of concern is the Polyphemus moth’s attraction to mercury vapor lights that may distract them from mating, thus impacting their populations in cities and neighborhoods. (Worth and Muller 1979)

Ornate Bella Moth

Most moths are nocturnal, meaning they are only seen at night but, this beautiful moth, the Ornate Bella Motha (Utetheisa ornatrix), can be seen fluttering in the daytime. A very distinguishing feature of this species of moth is the bright pink color seen when flying. When at rest, this coloring is often covered by the top wings. Their coloration greatly varies, which for a long time confused taxonomists who had multiple names for the species based on their appearance. It turns out they were all a single species.

These beauties can be seen through most of the Eastern United States through the Midwest. The eggs are small yellow spheres. The larvae are an orange color with black patches and white spots with many hair-like structures called setae. The pupae are encased in a brown and black sac covered in a light coat of silk. A common native host plant for these moths is the Crotalaria avonensis, a beautiful plant with yellow flowers. These plants produce pyrrolizidine alkaloids, which are toxic to many species, but not the ornate Bella moth. These moths consume the plants and thus become toxic themselves. This toxicity protects them for the short three weeks of their life.
