The Florida Medical Entomology Laboratory (FMEL) will offer its twenty-fourth Volunteer Nature Stewardship Class for the Oslo Riverfront Conservation Area (ORCA) in 2023 after a 2-year hiatus due to covid. This 6-session class will provide a foundation for understanding — and enjoying — the common habitats of Indian River County and what you may find in your yard. Each session will include outdoor activities..
Class participants are asked to “volunteer back” and share what they have learned at the ORCA, another nature preserve, a nature center, or in another venue. You craft how and where you “volunteer back”.
The class tentatively is scheduled to begin on Saturday, December 3, 2002 and in 2023 on Saturdays January 14 & 28, February 11 & 25, and March 4. Check back for the scheduled speakers/topics.
Please email Janice Broda at jbroda@ufl.edu if you are interested in participating in the 2023 class.

It’s that time of year, again! Love bugs flourish twice per year: April – May and August – September. Also know as honeymoon bugs, double-headed bugs, and March flies, these short-lived insects are harmless to people but hell on automotive…

When we visited the South Prong Slough on 6-16-2022, we saw the very beginnings of shoestring fern (Vittaria lineata), an epiphytic fern with an almost absolute allegiance to the trunk of cabbage palms (Sabal palmetto) in moist, mostly shady places.…
Usually, common beggarticks (Bidens alba) is abundant — along roadsides, mosquito control dikes, and in other disturbed places. Not so much this year, though. Perhaps, the lack of rainfall this year explains its relative absence. Common beggarticks are an annual…
