Fall is the absolute best season for wildflower watching in the Panhandle! When mid-September rolls around and the long days of summer finally shorten, giving way to drier air and cooler nights, northwest Florida experiences a wildflower color explosion. From the brilliant yellow of Swamp Sunflower and Goldenrod, to the soothing blue of Mistflower, and the white-on-gold of Spanish Needles, there is no shortage of sights to see from now until frost. But, in my opinion, the star of the fall show is the currently flowering False Foxglove (Agalinus spp.).
Named for the appearance of their brilliant pink flowers, which bear a resemblance to the northern favorite Foxglove (Digitalis spp.), “False Foxglove” is actually the common name of several closely related species of parasitic plants in the genus Agalinus that are difficult to distinguish by all but the keenest of botanists. Regardless of which species you may see, False Foxglove is an unusual and important Florida native plant. Emerging from seed each spring in the Panhandle, plants grow quickly through the summer to a mature height of 3-5’. During this time, False Foxglove is about as inconspicuous a plant as grows. Consisting of a wispy thin woody stem with very small, narrow leaves, plants remain hidden in the flatwoods and sand hill landscapes that they inhabit. However, when those aforementioned shorter September days arrive, False Foxglove explodes into flower sporting sprays of dozens of light purple to pink tubular-shaped flowers that remain until frost ends the season.

In addition to being unmatched in flower, False Foxglove also plays several important ecological roles in Florida’s natural areas. First, False Foxglove’s relatively large, tubular-shaped flowers are the preferred nectar sources for the larger-sized native solitary and bumble bees present in the Panhandle, though all manner of generalist bees and butterflies will also visit for a quick sip. Second, False Foxglove is the primary host plant for the unique Common Buckeye butterfly. One of the most easily recognizable butterflies due to the large “eye” spots on their wings, Common Buckeye larvae (caterpillars), feed on False Foxglove foliage during the summer before emerging as adults and adding to the fall spectacle. Finally, False Foxglove is an important indicator of a healthy native ecosystem. As a parasitic plant, False Foxglove obtains nutrients and energy by photosynthesis AND by using specialized roots to tap into the roots of nearby suitable hosts (native grasses and other plants). As both False Foxglove and its parasitic host plants prefer to grow in the sunny, fire-exposed pine flatwoods and sand ridges that characterized pre-settlement Florida, you can be fairly confident that if you see a natural area with an abundance of False Foxglove in flower, that spot is in good ecological shape!
The Florida Panhandle is nearly unmatched in its fall wildflower diversity and False Foxglove plays a critical part in the show. From its stunning flowers to its important ecological roles, one would be hard-pressed to find a more unique native wildflower! For more information about False Foxglove and other Florida native wildflowers, contact your local UF/IFAS County Extension office.

Bats bring a beneficial component to your property and community. This flying mammal is an exceptional nocturnal feeder of many insect pests and they are important pollinators of many food plants. However, several challenges face this night flyer, like reduced roosting locations, reduced foraging sights, and over use of pesticides.

There are ways to attract bats to your backyard, farm, and community. Placement of bat boxes with ample water sources nearby is a good start. Water sources are another area of importance to attract bats. Have you sat by a swimming pool and witnessed a bat swoop down and skim across the water? It is likely they are either consuming a little water after feeding on a large number of harmful insects or are wetting their modified arms (wings) to help remove dust and dirt to reduce drag on their wings. Bats are the only mammal that are capable of true flight, the modified wings with skin spanning between specific bone structures allows them to accomplish this amazing action.
We often refer to bats as blind, but they can see shadows if out during daylight hours. This poor sight is not helpful enough for survival, this is where their echolocation abilities come into play. Humans studied bats to better understand how they make the sounds that bounce of an object and back to their sensing system that includes exceptional hearing. They locate and consume insects this way. If this sounds familiar, sonar systems were developed by studying this process.
Bats are the major harvester of night-flying insects, many that carry diseases that impact humans and other animals. Insect prey for bats include cockroaches, mosquitos, moths, beetles, gnats and others. A Big Brown Bat can catch and consume 3,000 to 7,000 mosquitos a night. Multiple this by a large bat population the amount of harmful insects harvested can go into the thousands of tons in a year. This is a positive impact for our forest and agriculture lands against major pests.
Florida is home to 13 different species of bats. They are always on the hunt for warm, dry, dark areas that are either natural or manmade narrow crevices. Out of all of these species, 4 bats are the primary inhabitants of bat houses. The Evening Bat and Brazilian free-tailed Bat are the most common in the panhandle of Florida. The Big Brown Bat and Southeastern Bat can at times occupy houses.

You can often locate bats boxes at your garden and agriculture centers or order online. Another option is to build your own boxes. Just remember the best way to erect a bat box is on a tall post. It is recommended to set the boxes around 10 feet off the ground. Placing boxes on trees creates a setting for potential predators to approach and feed on bats. Snakes have been known to enter and feed on young bats that are not fully developed and at best are poor fliers.
As a reminder, never touch a bat or any other wild animals. Bats that are healthy are not found on the ground, so assume the bat is not health and may be carrying a disease. On a final note, enjoy sitting on the back porch and watching the acrobatics of these amazing mammals in the evening sky.

In a garden with a variety of flowers, pollinators will be abundant. Sometimes we don’t always recognize the specific pollinator when we see it, but there are some native pollinators that leave other signs of their activity. One of our medium-sized native bees will leave a distinctive calling card of recent activity in our landscape.

If you see some of the leaves of trees and shrubs with distinct circular notches on the edges of the leaves, you can be sure the Leafcutter bee is present. The females collect the leaf pieces to make a small, cigar-shaped nest that may be found in natural cavities, such as rooting wood, soil, or in plant stems. Each nest will have several sections in which the female places a ball of pollen and an egg. The emerging larvae then have a plentiful food source in order to develop into an adult bee.
When identifying a leafcutter bee in your landscape, look for a more robust bee with dark and light stripes on the abdomen. These bees also have a hairy underside to their abdomen where they carry the pollen. When loaded with pollen their underside will look yellow.
Leafcutter bees are solitary bees that are not considered aggressive. A sting would only be likely if the bee is handled. Your landscape will have many plants that a leafcutter may use for nesting material. The pollinating benefits of these bees far outweigh any cosmetic injury to the plant leaf margins.
