Common Eastern Bumblebee

When people hear bumblebee, their first reaction is fear since their sting can be painful and unpleasant, and some people have an allergic reaction to their sting. Even though they can sting, they are one of the most beneficial animals in nature, improving our lives daily! Bumblebees have fur all over their bodies; these little hairs collect and trap pollen, which the bees carry from one plant to another. Little black hairs cover the head, abdomen, and legs. The thorax is yellow. Bees are pollinators, moving from plant to plant while searching for protein-rich nectar. The Common Eastern Bumblebee (Bombus impatiens) pollinates flowers and numerous fruit and vegetable crops. Bees form the foundation of the food chain for other species, including humans.
The Common Eastern Bumblebee is found throughout the east coast from Maine to Florida and west through Ohio. They fly near gardens, farms, and backyards in spring and summer. Their nests are located in woodlands and fields. Bumblebees are important food sources for other animals, such as birds, spiders, wasps, and small mammals.
Eastern Common Bumblebees are social insects living in colonies. Bumblebees have annual nests that can have about 300 to 500 individuals! Newly mated queen bees hibernate over winter, then emerge in early spring to search for a nest site. Worker bees develop first, followed by males and new queens at the end of summer. Worker bees, males, and the old queen die in the fall. Due to habitat loss, invasive species, parasites, and pesticides, pollinators worldwide are in decline.
Cool Fact! Bees with stingers are all females! They are the workers and queens. Males cannot sting and are called drones.
Another Cool Fact! Unfertilized eggs develop into males, and fertilized eggs develop into females.

Two Striped Walking Stick

The Two Striped Walking Stick (Anisomorpha buprestoides) (Stoll) is a common stick insect in Florida. There are a few other names that this insect is referred to, devil’s riding horse, prairie alligator, stick bug, witch’s horse, devil’s darning needle, scorpion, and musk mare. That last name was given to this species because of its capability to squirt a strong-smelling defensive spray that can painfully irritate the eyes and mucus membrane.
The Two Striped Walking Stick is large and stout (not a common physical trait of stick insects); it has three long black strips or two thick white strips, depending on how you look at them. Females are much larger measuring 67.7 mm in length while males are much smaller and slender measuring 41.7 mm.
Like any stick insects, these species are herbivores, feeding on the leaves of trees and shrubs. Not much is known about their life history, but many have observed that females will secrete her eggs on the ground, mainly during the Fall season. Stick insects will use their secretion if they perceive a threat, this occurs typically with physical contact.
These guys may be small but there have been studies that showed the effect the stick insects’ secretion can cause, it can be highly irritating to the eyes of both humans and animals and can cause excruciating pain.
Cool Fact! This species can be commonly found with the smaller male riding on top of the larger female.

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.

Hover Fly

The hoverfly (Allograpta obliqua) can be found in most of the continental United States, parts of Canada, and Mexico. It is a colorful and common fly in Florida.
Just like its name suggests, it can hover or fly backward. Adults usually visit flowers for nectar; they have also been seen around aphid (greenfly and blackfly) colonies, laying their eggs and feeding on honeydew secreted by the aphids. Adults aid pollination as they can pollinate some plants.
The larvae stage of this species are essential predators as they feed on aphids, which are crop-damaging insects. When larval populations are high, they can reduce aphid populations by 70 to 100%!
Adults occur throughout the year in northern Florida; they are more abundant during spring and summer. In southern Florida, they are also abundant during winter. Their life cycle varies from three weeks in summer to nine weeks in winter. They lay their eggs singly on a leaf or twig, where aphids are abundant. They hatch for two to three days during the summer and around eight days in the winter. When it is time for the larvae to pupate, they will fasten themselves to a leaf or twig. The pupal stage takes up to ten days in summer and 18 to 33 days in winter.

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.

Brunner’s Mantis aka Northern Grass Mantis

The Brunner’s Mantis (Brunneria borealis) is also known as Brunner’s stick mantis or northern grass mantis. It is native to the southern United States. The female mantis lays her eggs in an egg case. Nymphs emerge looking much like an adult and go through several molts as they grow. The Brunner’s Mantis is a carnivore and captures its prey of insects and grasshoppers by ambush. Look for these 2.5 – 3.5 inch hard-to-see insects in tall grass.
Fun Fact: There are no males in this species. Females reproduce asexually through parthenogenesis.

Black Bee Killer and Batesian Mimicry

The Black Bee Killer, Mallophora atra (also known by the species name M. nigra), is a rarely seen member of the robber fly family. They are only found in Florida, with a single specimen sighted in North Carolina. Similar in structure to the more common Florida Bee Killer (M. bomboides), the black bee killer has an all-black abdomen and scutellum, as seen in the photo. There is some discussion as to if this is a separate species or a color variant of the more commonly seen Florida bee killer.
The black bee killer is quite similar in its life history to the other 2 bee killers found in Florida. They are large flies that are a great example of Batesian mimicry. Their bodies mimic bumblebees or carpenter bees and even make a buzzing sound when in flight! Batesian mimicry is when a harmless species evolves to have a similar appearance to another more dangerous species. In the case of M. atra, predators avoid eating bees due to the painful sting. This allows the flies to hunt in the open with less fear of being attacked themselves.
Other, more common Batesian mimics are the monarch butterfly and its mimics, the gulf fritillary, queen, and viceroy butterflies. In reptiles, you have the venomous coral snake, and its mimics the scarlet kingsnake and the scarlet snake. Southern and eastern hognose snakes resemble their more dangerous cousin, the pygmy rattlesnake.
The black bee killer inhabits open habitats where they perch on small branches and weed stalks, waiting for their prey to pass by. That prey includes primarily social bees such as honey bees, carpenter bees, bumblebees, and a few species of wasps. Honey bees seem to be a favorite food source due to their size and slower flight patterns. The female black killer bee lays eggs in the soil, but not much is known about the larval development of these robber flies. Other species of Mallophora larva have been known to parasitize on the larva of scarab beetles.

Southern Plains Bumblebee

Southern Plains Bumblebees, Bombus fraternus, are found from New Jersey south to Central Florida and from the eastern coast to the Rocky Mountains. Females are typically smaller than males with the exception of the queen. Males can be distinguished by the two bands across the abdomen. These bees are active from spring through fall. They feed on a variety of native flowers including goldenrod, blazing stars, milkweed, and flowers within the Asteraceae family.
Southern Plains Bumblebees are endangered. The greatest threat to this species is declining habitat. By adding native flowering plants to your landscape, you can help create a habitat for this declining species.

Great Blue Skimmer

Great Blue Skimmers, Libellula vibrans, are found in forested wetlands, swamps, and near lakes and ponds where still or slow-moving shallow water is present. These are large dragonflies that measure 2.3 inches and are often called King Skimmers.
The bodies of adult male Great Blue Skimmers are blue while the female’s body is brown. After fertilization, females pick up a drop of water to help eggs stay on the shore. Once the larvae hatch, they return to the water where they develop into adults.

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)

Ebony Jewelwing Dameselfly

Ebony Jewelwing Dameselfies, Calopteryx maculata (Beauvois) are most often seen near slow moving streams. Both males and females have iridescent green bodies. The males wings are dark and the females wings are bronze colored with at white spot on the edge of the foreweings. They are large dameselflies that grow to 2.25 – 3 inches and have wingspans of 1.5 – 2.25 inches .

Female Ebony Jewelwings lay their egss on aquatic debris that forms a raft or dam in a stream. The naiads or juvemiles hatcht and feed on small aquatic prey. The naids are preyed on by frogs, fish, and birds. Adult Ebony Jewelwings are prey for frogs, fish, spiders, birds and the larger dragonflies.

Look for this damselfly that is endemic to eastern North America in Florida as far south as Brevard County on the eastcoast and Desoto County on the west coast. Ebony Jewelwings often rest on branches or leaves where their iridescent bodies shimmer in the sunlight.

Eastern Black Swallowtails

Black Swallowtail (Eastern)

Eastern Black Swallowtails, Papilio polyxenes, are also known as American swallowtails. They are commonly found throughout Florida in gardens, along the sides of roads, in pastures, and in parks. Three or more generations are produced each year.

A female black swallowtail lays a single yellow egg on a host plant in the carrot family. The caterpillar is green with black stripes and yellow spots. If parsley or dill was chosen as the host plant, the hungry parsley caterpillar will devour the plant in your garden.

Cloudless Sulpher

Cloudless Sulpher

Cloudless sulfurs, (Phoebis sennae), live in Florida year-round. These beautiful, bright yellow butterflies are hard to miss with their wingspans of 2 – 3 inches. Look for them in sunny, open areas such as along roadsides and in pastures, fields, and meadows.

Cloudless Sulfurs can be seen in large numbers during the fall migration season. Many spend their winters in Florida south of Gainesville. Nectar plants include red morning-glories, scarlet creeper, and cypress vine, scarlet sage, and Salvia. Cloudless Sulfurs prefer various species in the pea family as host plants where females lay a single egg.

Mosquito

 

The most common Mosquito in Florida is the Aedes aegypti species. The females are carriers of West Nile Virus, Eastern Equine Encephalitis, Dengue fever, Chikungunya, and Zika virus. Female mosquitos need blood to produce eggs. Therefore they love to live where people and pets are abundant.

You might be surprised to hear that 80 species of mosquitos call Florida home. This means that Florida has more mosquito species than any other state in the country. Of those eighty species, only 33 bother people and pets. We can narrow it further than that, 13 make people sick.
Some species are only located in certain areas of the state and others throughout the state. Mosquitos can spread a host of diseases from yellow fever, Zika, dengue, encephalitis. In your pets, they can spread heartworm and equine encephalitis. You can’t really avoid mosquitos as some feed during the day and others at night. You will run into one or the other eventually. In Southern Florida, mosquito season begins as early as February and continues through most of the year. In Northern Florida, mosquito season starts in March and follows a similar pattern. The warmer it is, the more active mosquitoes will be, especially at dusk and dawn. Permanent water mosquitos are attracted to standing pools of water, which they need for their eggs to hatch. Females will lay their eggs on the water surface, and the eggs will typically hatch in about 24 hours. Water is necessary to complete the life cycle, and soon the larva will change into a pupa and then emerge into an adult hungry for blood. Florida permanent water mosquito species include Anopheles quadrimaculatus, Culex quinquefasciatus, and Mansonia dyari. Make sure your house and yard are free of standing pools in flowerpots, buckets, and containers. Cut back overgrown yards. Lush plant life can be beautiful, but it’s also a mosquito magnet. They love resting in dense vegetation that can keep them warm and moist. Floodwater mosquitos lay their eggs in moist soil, not standing water. One female floodwater mosquito has the potential to lay 200 eggs per batch in moist areas. The eggs need to dry out before they can hatch into larvae. The eggs survive in the dry soil, in cracks and crevasses. Once the rain from storms begins, the areas become inundated with water, and the eggs are able to hatch. Florida floodwater mosquito species include Culex nigripalpus, Ochlerotatus taeniorhyncus, and Psorophora columbiae. Seal up cracks and holes in windows and doors, anything that may let a mosquito in. If you have a patio that is not enclosed, use mosquito netting. It is recommended that you use a sturdy net and contain 156 holes per square inch at a minimum. Frogs, birds, dragonflies, and certain kinds of fish all eat mosquitoes. Attract birds by putting up a bird feeder or introduce beneficial bugs into your garden to help keep mosquitoes away. You won’t get every mosquito, but it may help in cutting down the numbers.

What can you do to stop mosquito breeding in your yard?
Mosquitos only need 1-2 centimeters of stagnant water to breed.

1. Change water in birdbaths 2x/week.
2. Be sure flower pots and the dish underneath does not contain standing water.
3. Be sure gutters are debris-free, so water will not collect in a leaf “dam.”
4. Bromeliads are a perfect habitat for mosquitos to develop. Flush bromeliads with a garden hose 2x/week.
5. Check yard toys and yard ornaments for standing water.
6. Check for leaks from outdoor faucets and around your air conditioner.
7. Is there standing water in your boat or any other vehicle stored outdoors?
8. Look for standing water near your swimming pool, pool equipment, and pool toys.
9. Check for standing water in holes in trees and bamboo.
10. Walk around and look for water in things like trash cans, trash can lids, and any container or object where water can accumulate.
