For many Floridians, gardening is a window into learning the cycles of the natural world. Understanding pollination, distinguishing beneficial insects from harmful ones, creating compost, or knowing what time of year to apply iron supplements are important for a gardener to be successful. While we have our share of campers, hikers, and kayakers, over the years Extension agents have found that some of our best Master Naturalist students are those with fond memories of farming or gardening as children or adults.
If you have always been fascinated by the natural world and how plants, animals, and people interact, you might be a perfect candidate for the Master Naturalist program. Offered periodically in almost every county in Florida, this adult educational course combines classroom sessions with field instruction, typically over a six-week period. At graduation, students present an original project, which may vary from creating an exhibit, a children’s book, or even an environmental non-profit organization.
Master Naturalist students vary in backgrounds from retired military and teachers to park rangers and college students. Many Master Gardeners find the courses a helpful addition to their training, and utilize their newly gained knowledge when working with clientele. At completion, students receive an official Florida Master Naturalist certificate, pin, and patch.
The traditional 40-hour courses cover Upland, Coastal, and Freshwater Wetland habitats, while the newer “special topics” cover Conservation Science, Environmental Interpretation, Habitat Evaluation, and Wildlife Monitoring. A new “restoration” series has begun with the Coastal Restoration class, which kicked off in Escambia and Santa Rosa counties and is currently being taught in Bay. Extension agents will be offering several classes in the Panhandle this fall—check out the FMNP registration site to see when a class will be offered near you!
I respect the fact that wasps can sting when threatened or disturbed. But I also respect the fact that they are beneficial.
Every time I’ve been stung by wasps, I either accidentally disturbed a nest that I didn’t know was there or I intentionally disturbed the nest and paid the price.
Paper wasps are common in Florida. They frequently construct and attach their paper-like nests to building eaves or the ceilings of porches. The adults seek out caterpillars, which they sting and paralyze. They then take the caterpillars back to their nest and place them in individual cells as food for the developing larvae.
I’ve witnessed the paper wasp as it stings and carries away a caterpillar from my vegetable garden. They are busy insects and are doing us gardeners a favor by reducing the population of caterpillars in our landscapes and gardens.
There are other beneficial wasps in Florida. Mud daubers, for example, build their mud-like nests on the sides of buildings close to human activity.

The mud dauber is not as aggressive as the paper wasp. It rarely stings people. It stings and paralyzes spiders. The mud dauber lays an egg on each paralyzed spider and seals it inside a chamber in its earthen nest. Upon hatching, the wasp larva feeds on the body of the spider. An emergence hole is made as the young wasp leaves the mud nest.
It may not be wise to tolerate all wasp species living in close proximity to your home. Even though yellow jackets, a type of wasp, could be considered beneficial, they are too aggressive and too likely to repeatedly sting to have as close neighbors. I also would be concerned with any type of wasp or bee nest existing in close proximity to individuals with a known allergy to insect stings.
Just because an insect has the ability to sting, it’s not all bad. Wasps can serve a beneficial purpose. But you’ll have to decide for yourself how close to you they can build their nests. The front porch may be too close.

On June 6th, we held an Invasive Species Workshop: Air Potato Challenge and Species Awareness day at the UF/IFAS Extension Office in Panama City. Over 700 air potato leaf beetles were distributed to more than 30 sites in Northwest Florida by citizen scientists to help manage the invasive air potato vine!
Rick O’Connor, UF/IFAS Extension, tells us about the ball python, a potential invasive species. Rick also provides an overview of keeping pythons and other snakes as pets. http://edis.ifas.ufl.edu/pdffiles/UW/UW34100.pdf
Holli Nichols, FWC, tells us about the Wildlife Assistance program for homeowners and property owners. Holli helps out find solutions for negative encounters with Wildlife. Most problems are easily solved and she provides a few tips. Holli also tells us about the FWC Pet Amnesty Program for Exotic Pets. Watch to learn more. http://myfwc.com/conse…/you-conserve/assistnuisance-wildlife
Kira Burdeshaw, SCN of NW FL, shows off the tokay gecko we found at the Extension office on the front porch earlier in May. The Gecko moved in with Kira and her other reptiles at the Science and Discovery Center.

Derek Fussell with FWC Invasive Aquatic Plant Management talks about Giant Salvinia, a species of concern for Deer Point Lake in Bay County, Florida. Here’s a link to a story about the discovery of giant salvinia in Bay County from 2016 https://nwdistrict.ifas.ufl.edu/…/nisaw-2016-working…
Derek Fussell shares a behind the scene’s view of their new boat for controling aquatic plants in Bay County and Northwest Florida. We will visit with Derek and Jamie later and show some of the aquatic invasives they work to control everyday!
National Pollinator Week is only recognized in June, but efforts to encourage pollinators shouldn’t end then.
Pollination occurs when pollen grains are moved between two flowers of the same species, or within a single flower, by wind or animals that are pollinators. Successful pollination, which may require visits by multiple pollinators to a single flower, results in healthy fruit and fertile seeds, allowing plants to reproduce. Without pollinators, we simply wouldn’t have many crops!
Worldwide, approximately 1,000 plants grown for food, beverages, fibers, spices, and medicines need to be pollinated by animals in order to produce the goods on which we depend. Foods and beverages produced with the help of pollinators include blueberries, chocolate, coffee, melons, peaches, pumpkins, vanilla, and almonds.
About 75% of all flowering plants rely on animal pollinators and over 200,000 species of animals act as pollinators. Of those, about 1,000 are hummingbirds, bats, and small mammals. The rest are insects such as beetles, bees, ants, wasps, butterflies, and moths. Western honey bees are the most common.
Most species of bees don’t sting. Although all female bees are physically capable of stinging, most bee species native to the U.S. are “solitary bees,” that is, not living in colonies and don’t sting unless they are physically threatened or injured. Only honey bees are defensive and may chase someone who disturbs their hive.
It is wise, though, to avoid disturbing any bee or insect nest.
What everyone can do for pollinators:
Watch for pollinators. Get connected with nature. Take a walk, experience the landscape and look for pollinators which are most active midday in sunny, planted areas.
Reduce your impact. Reduce or eliminate your pesticide use, increase green spaces, and minimize impervious surfaces.
What you can do to create a pollinator-friendly habitat:
Design your garden so that there is a continuous succession of plants flowering from spring through fall. Check for the species or cultivars best suited to your area.
Plant native to your region using plants that provide nectar for adults plus food for insect larvae, such as milkweed for monarchs. If you do use non-native plants, choose ones that don’t spread easily, since these could become invasive.
Select old-fashioned varieties of flowers whenever possible because breeding has caused some modern blooms to lose their fragrance and/or the nectar/pollen needed to attract and feed pollinators.
Avoid pesticides, even so-called “natural” ones such as Bacillus thuringiensis (Bt). If you must use them, use the most selective and least toxic ones and apply them at night when most pollinators aren’t active.
Supply water for all wildlife. A dripping faucet or a suspended container with a pinhole in the bottom is sufficient for some insects. Other wildlife need a small dish of water.
Provide water for butterflies without letting it become a mosquito breeding area. Refill containers daily or bury a shallow plant saucer to its rim in a sunny area, fill it with coarse pine bark, sand or stones and fill to overflowing with water.
Fun facts:
A tiny fly (a “midge”) no bigger than a pinhead is responsible for the world’s supply of chocolate
One out of every three mouthfuls of food we eat is delivered to us by pollinators.

Air potatoes got you down? Have no fear, for the Air Potato Challenge is coming to Leon County!
Register now to attend the Air Potato Challenge event on May 18, 9 a.m. to 12 p.m. at the FAMU Center for Viticulture and Small Fruit Research (6361 Mahan Drive, Tallahassee, FL) and receive a supply of air potato beetles to use on your property.
After years of testing, air potato beetles became available as a biological control in 2012 to help combat the invasive herbaceous perennial air potato vine (Dioscorea bulbifera). Air potatoes arrived in south Florida from China in the early 1900s and have steadily crept north until they are now invading the Panhandle Region. Fortunately, air potato beetles have dietary requirements that are very specific, relying strictly upon air potatoes to complete their life cycles.
This is why a team of researchers and Extension agents have come together to help spread air potato beetles as a biological control strategy. Many agencies and counties are involved in this effort, including UF/IFAS Extension St. Lucie County, UF/IFAS Indian River Research and Education Center, the Florida Department of Agriculture Division of Plant Industry, the USDA, Florida Fish and Wildlife, UF/IFAS Extension Leon County, and Florida A&M University.
With cool, foggy mornings you may have noticed the large number of spider webs hanging on low vegetation. Some of them have unusual shapes. One of the most notable is the bowl and doily spider. This spider (Frontinella pyramitela) is a species of sheet web weavers found throughout the United States, including Northwest Florida.
It is a small spider, about 3-4 mm (0.16 in) long, boldly marked with black and white stripes on the abdomen, a brown cephalothorax, and brownish legs. They weave a fairly complex shaped webs only a few inches across, usually well off the ground and stretched between twigs or other objects. Webs consist of an inverted dome-shaped web, or “bowl”, suspended above a horizontal sheet web, or “doily”, hence its common name. The webs are approximately circular when viewed from above, where there is a tangled scaffold “knock down” threads of silk invisible to flying insects. The webs are commonly seen in weedy fields and in shrubs.
Small flies, gnats and other small insects crash into the strands of barrier silk and fall down into the non-sticky webbing. The spider hangs from the underside of the “bowl”, and bites through the web, pulling the prey through in order to consume them while resting comfortably on the “doily”. Bowl and doily spiders serve a very important ecological role by controlling human-biting and plant damaging insects.
Among web-building spiders, bowl and doily spiders (Frontinella pyramitela) are unusual because both males and females often cohabitate. The males rarely build webs, however, and so depend upon females ‘ snares for food. These cohabiting males capture about 32% of the prey that hit the web despite the female’s efforts to capture the same prey.
Mating in this species occurs on the underside of the bowl of the female’s web and is preceded by a complex vibration- and chemical-mediated courtship during the late summer. Eggs are laid in silken sacs in the web or hiding in leaf litter on the ground. Both eggs and adults have been known to overwinter. Like all spiders, bowl and doily spiders develop through simple metamorphosis: spiderlings look like tiny adult spiders (but with lighter coloration), and shed their outer skin in order to grow. Most sheet web weavers live only one year.
