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.

Blue Crab

Blue crab (Callinectes sapidus) lives through the Atlantic Coast and in the Gulf of Mexico. The blue crab shell, also called a carapace, is blue to olive green, the shell can reach 9 inches across. The claws are bright blue, with mature females having red tips on the claws as well. They have four pairs of legs, the first three are walking legs, while the last rear pair are swimming legs that look like paddles.
Blue crabs can live up to 3-4 years, reaching maturity at about 12 to 18 months. Water temperature does affect growth rates, they grow more quickly in warm waters. In the Gulf of Mexico, they can mature in about a year, but in the Chesapeake Bay, it can take up to 18 months. As the crab grows, it will “molt”, which is shedding its hard shell. When molting occurs, they will lose their hard parts, which can make it difficult to determine age. Males will molt multiple times during their lives, while females will only molt once, which is before mating. Blue crabs are bottom-dwellers, beds of submerged aquatic grasses are used for food, nursery habitat for young, and shelter during mating and molting.
These shellfish are important predators of benthic communities and are prey for many fish species. They will eat almost anything, including clams, oysters, mussels, smaller crustaceans, freshly dead fish, plant, and animal detritus, and other blue crabs that are smaller and soft-shelled. Crabs become prey to large fish, some fish-eating birds, such as great blue herons, and sea turtles.
When mating occurs, a male will cradle a female in a pose known as a “doubler” for a few days before her last and only molt. The male will stay with her after mating until her shell hardens, to ensure no other male will mate with her. When the eggs hatch the larvae will go through multiple molts in high-salinity coastal waters.
Cool Fact! Callinectes sapidus is translated from Latin which means, ‘beautiful savory swimmer’.

Eastern CoachWhip

There are six subspecies of coachwhip snakes that are currently recognized, but the Eastern Coachwhip (Masticophis flagellum flagellum) is the only one that occurs in Florida. These nonvenomous snakes are one of the longest snakes seen in Florida. Coachwhips are very observant; they often rest or crawl with their head and neck raised above the ground as they scan the environment. They are also excellent climbers.
Adults can reach 42-60 inches in total length. This long, slender snake typically has a dark brown or black head, neck, and front part of the body; towards the back end, it becomes light tan. The head is large and narrow, with large scales over the eyes. Their eyes are large and prominent with round pupils and yellow irises. Juvenile appearances are slightly different, with brown or tan dark cross bands down the neck and back. The juvenile pattern will gradually change to adult one in about two years.
Coachwhips are abundant; their habitat is typically hot and dry with open canopies. These snakes are extremely fast and agile. When approaching, they will typically flee for shelter. Though if cornered, both juveniles and adults will strike an attacker and will rapidly vibrate the tip of their tail, producing a buzzing sound in leaf litter. These snakes are typically nonaggressive, and striking is their last resort.
Coachwhips are diurnal, meaning they are active during the day, predators, they feed on small mammals, birds and their eggs, other reptiles, frogs, and insects. Because these snakes are in Florida, lizards are most likely what make up a primary part of their diet. They are not true constrictors; the snakes overpower their prey by grabbing with their jaws and pressing down against the ground until it stops struggling or by quickly swallowing it alive.
Coachwhips are not true constrictors and overpower their prey by simply grabbing it in their jaws and pressing it against the ground until it stops struggling or by quickly swallowing it alive.
In Florida, females lay around 4-24 eggs. Eggs are laid in loose soil, debris, leaf litter, rotting logs, or animal burrows. Young will hatch between August and September.
Cool Fact! The name “Coachwhip” comes from the large tan scales on its long tail, which looks like a braided bullwhip.

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.

Saltmarsh Caterpillar

The saltmarsh caterpillar (Estigmene acrea) (Drury) is a native insect found throughout the United States. It is common in the southern United States as a pest. Adults are large moths; wingspan can measure 3.5 to 4.5 cm and are very distinct. The wings are mostly white in color; there are generally many small, irregular black spots. The male hind wings are yellow, the underside may also have a yellow tint, and the female is white. The abdominal segments are yellow with a series of large black spots dorsally.
Females generally live only four to five days; however, they can produce more than one cluster of eggs. She can produce 400 to 1000 eggs in one or more clusters. Eggs are tiny and spherical; they are initially yellow and soon turn gray in color. Eggs will hatch in four to five days. There are five to seven instars.
Larvae are active dispersers, a behavior not typical among caterpillars. Late instar larvae will move over the soil searching for food and can be found individually or in groups. Caterpillars damage crops, mostly during fall. With each succeeding instar consumption of plants doubles. When pupation occurs, they are on the soil among leaf debris. When pupation is complete, it is dark brown, measuring 30 mm, and lasts about 12 to 14 days.
Broadleaf weeds are the initial host plants for this species, though larvae will commonly disperse late in the growing season to damage vegetable and field crops. The favored weed host are usually pigweed (Amaranthus spp.); however, many others can be consumed, such as anglepod (Gonolobus spp.).; sicklepod (Cassia tora); dog fennel (Eupatorium capillifolium); ground cherry (Physalis spp.); and mallow, (Anoda spp.).
Agricultural management commonly used insecticides on saltmarsh caterpillars. Baits are not an effective method to manage the species. Physical barriers can be used such as ditches or trenches with steep sides to prevent the invasion of crops.
Cool Fact! Saltmarsh caterpillar’s name is derived from being a pest of Saltgrass hay grown around Boston. Though ironically, grasses are not a preferred host plant.

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.
