Giant Leaf-footed Bug

The giant leaf-footed bug (Acanthocephala declivis), is a strikingly large insect found throughout parts of North America. This bug gets its name from its distinctively shaped hind legs, which resemble leaves and are used to camouflage it in its environment. The body of this insect is typically brown or gray and is about an inch in length. This species has a pronotum, a place that covers the thorax that extends to the abdominal region. It also has dull tubercles and rounded nodules in the middle of the pronotum. Giant leaf-footed bugs feed on the sap of various plants, and they can sometimes be a pest to agricultural crops such as tomatoes and citrus. While they may not harm humans, these bugs can be quite a nuisance when they invade homes and gardens.

June Bug

The Green June Beetle, Cotinis nitida, is the second most common June bug in Florida. Most of this native June bug’s life is spent underground where it begins as an egg. The grub dines on roots before pupation. Wild animals will dig in the soil to consume the larvae that are full of nutrients.
The iridescent, emerald-colored adult Green June Beetle emerges and will begin the process of mating and laying eggs. The June bug will bore into fruits and sip nectar from wildflowers and tree blossoms. This common beetle at up to 1 inch long is a great source of protein for birds, and wild animals such as raccoons and skunks. Photo credit: Andy Waldo

Ladybug

Ladybugs (Coccinellidae), aka Lady Bettles, a worldwide symbol of good luck, are best known for their voracious appetite for aphids. As omnivores, they dine on whiteflies, mites, mealybugs, scale insects, and mildews and can devour up to 5,000 aphids in their lifetime.
 
Ladybugs live two to three years and grow between 1/3 and slightly over 3/8 of an inch. Female ladybugs lay golden eggs on the underside of leaves, often near an aphid colony. In a few days, the eggs hatch, and the larvae will eat between 350 and 400 aphids within two weeks before becoming adults.
 
Ladybugs’ strikingly bright colors make them easily identifiable but unappealing to predators. A fluid secreted from the joints in their legs also makes them taste bad. Ladybugs will outsmart their predators by secreting the foul smell while playing dead.
When temperatures fall, Ladybugs enter diapause and live off their stored reserves for up to nine months. When the temperature warms to 55°, they resume everyday life. As they take flight, their tiny wings beat about 85 times per second.
 
Did you know Ladybugs went to Outer Space? A space shuttle carried four ladybugs and a jar of aphids as part of a zero-gravity experiment. Ladybugs did not need gravity to dine on the aphids.
 
It is not a good idea to purchase Ladybugs. Most that are for sale have been wild-caught. No studies have been done to determine whether or not any harm is being done to the Ladybug population in the area where they are caught. This can result in more pesticide use when ladybugs are not present. Ladybugs are not tested for disease before shipment so that they could introduce disease-carrying pathogens to native Ladybugs in your area. Ladybugs introduced to your garden will fly away if there are insufficient food sources.
 
The best way to attract some of Florida’s 98 species of Ladybugs to your landscapes is to avoid chemicals. Learn to identify the larvae and leave them alone to eat the harmful pests in your garden.

Ceraunus Blue Butterfly

 

Take time to stop and look at the little things.

With a wingspan of only 1 to 1 3/16 inches, the Ceraunus Blue Butterfly (Hemiargus ceraunus fabricius) is easy to overlook. This tiny butterfly is commonly found flitting just above the vegetation in sunny habitats, including parks, scrubs, along roadsides, and your Florida landscape.

Look for the prominent orange-rimmed black marginal spot on the hindwing. Females are usually a darker blue. Tiny blue eggs are laid on the flower buds of herbaceous legumes. The host plant provides food for the larvae with flowers, buds, and new growth. Multiple generations are born each year.

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.

Halloween Pennant Dragonfly

Halloween Pennant Dragonfly (Celithemis eponina).

This not-so-spooky dragonfly gets its name from its orange and black coloring. Yellow markings can be found on females and juvenile males. As males mature, their coloring starts to turn into a more vibrant color of orange. This is the largest species of pennant dragonfly in eastern North America. They can commonly be found around lakes, streams, or other wetland areas and are most active in the morning.

Schaus’ Swallowtail

The Schaus’ Swallowtail (Heraclides aristodemus ponceanus) is a large black and yellow butterfly endemic to Florida. This butterfly is found only in Florida and is restricted to intact tropical hardwood hammocks.

The Schaus’ swallowtail was listed as a federally threatened species on April 28, 1976. It was reclassified as a federal endangered species on August 31, 1984. Population estimates range from 800 to 1200 individuals. It remains the only federally listed butterfly in Florida.

Once ranging from the Miami area south through the Florida Keys, the Shaus’ swallowtail is currently restricted to only a few remnant tropical hardwood hammock sites on the south Florida mainland, northern Key Largo, and several small islands within Biscayne National Park. Adults fly slowly and leisurely and are very adept at flying through the dense hardwood hammock.

Adults have a wingspan range of up to 2.3 inches with females being the largest. Males have yellow-tipped antennae. Their wings’ upper surface is black with a row of yellow or white spots and a broad yellow or white band. The hindwing tails are outlined in yellow. The undersides of the wings are yellow with brown markings and a broad blue and rust-colored band.

The Schaus’ swallowtail produces one generation each year from April to July with the peak time occurring typically from mid-May to mid-June. Adult emergence and reproduction are correlated with the beginning of the Florida rainy season. However, the pupae may remain in diapause for more than one year if optimal weather conditions are not present. Females lay green eggs singly on new growth. The developing larvae then feed on the young growth.

Listed as an endangered species, threats to the remaining population include the loss of genetic diversity due to inbreeding, climate-related impacts such as drought, habitat disturbance from fire, tropical storms or hurricanes, mosquito spraying, and loss of habitat. Hurricane Andrew left behind only 73 butterflies in 1992 after sweeping through the butterflies’ home range. Because their habitat is limited, it is possible that a single hurricane can make the Schaus’ Swallowtail extinct. However, the protected status and their rebounding numbers after Hurricane Andrew bring renewed hope that this gorgeous butterfly will survive and thrive in our beautiful state.

Lightning Bug

Let’s be a kid again with the Firefly/Lightning Bug!

Remember those nights of wandering outside in the spring and summer and being surrounded by amazing little flying strobe lights. They would come out at dusk and stay only for a few hours. We captured them in glass jars and looked in amazement as we tried to figure out how their lights worked.

Fireflies are a good indicator species for the health of an environment. Unfortunately, these little miracles of life are on the decline throughout the world because of overdevelopment, pesticide use, and yes, light pollution.

The best thing you can do to support fireflies is to stop using lawn chemicals and broad-spectrum pesticides. Firefly larvae eat other undesirable insects. They are nature’s natural pest control.
If you miss seeing these little buggers, you’ll be happy to know Central Florida’s firefly season is at the end of March and early April. In fact, Blue Springs State Park stays open a little past their usual closing time and has guided tours at this time so you can enjoy nature’s light show.
