Young's Deepdigger Scarab Beetle

This is Young's Deepdigger Scarab Beetle (Peltotrupes youngi), which is mostly active from November to April, and we are highlighting this species because it is very active now and because we have recently received distributional information about it. It only lives in a very small area in Florida in and near Ocala National Forest primarily in open, well-managed, scrub habitat.

The related Florida Deepdigger Scarab Beetle (Peltotrupes profundus), above, is known from surrounding areas in xeric (very dry) habitat in the northern Florida peninsula.

The above image is of Henry Howden, who was the world expert on the family of Earth-boring Scarabs, standing  in a hole that he dug to excavate a Deepdigger Scarab's burrow to learn more about its biology. These beetles dig burrows about 6 feet deep, and sometimes down to 10 feet, which is pretty impressive since it’s only about ¾ of an inch long! It provisions its burrow, where is lays its eggs, with pine needles, pine cones, and leaves.  Adult diet is unknown, but they have been recorded under a nibbled-on mushroom, under horse dung, captured in pitfall traps baited with dung, and will gobble down moistened dry cat food in captivity.

Fresh burrow mounds of Deepdigger Scarabs have a "chunky" texture to them because the beetle loosens sand at the bottom and then pushes it all the way up the burrow and out the entrance.

Although they have somewhat impressive mandibles ("jaws"), I have never had a Deepdigger Scarab try to bite me and I think that this one just posed nicely for me because it wants me to put it back down so that it can get some more food.  

Many thanks to Paul Moler for sending me these interesting and beautiful beetles so that I could get pictures of them and write about them.

Noteworthy Discoveries: Rare Plant Finds in the Florida Panhandle

Ann Johnson, FNAI community ecologist, has been busy this fall season looking for rare plants at Box R Wildlife Management Area under a contract with the Florida Fish and Wildlife Conservation Commission (FWC).  A rare plant survey was last conducted on the site back in 2007, and a lot has changed since then!  FWC management activities have focused on thinning densely planted pine trees, and the application of prescribed fire to restore former flatwoods and prairies.

Ann’s efforts and sharp eyes have found two rare plants never before documented on Box R, both of which depend on frequent fire to bloom and persist.  Pine-woods aster (Eurybia spinulosa) is a small herb found only in mesic and wet pine flatwoods in the central Florida Panhandle.  This species is considered to be critically endangered due to its rarity, limited range, and threats to its habitat.  Wiregrass gentian (Gentiana pennelliana) is a rare winter-blooming species with showy white petals, occurring in open wet prairies.

Cathy Ricketts, biologist at the nearby Apalachicola River Wildlife and Environmental Area, also found this beautiful plant growing in a restoration wet prairie location.  We are hoping for more exciting field finds this spring!

Frost Flowers

Frost flowers (also known as ice flowers, ice blossoms, and frost castles) are delicate ribbons of ice that can form when the air temperatures are freezing but the ground remains unfrozen.  Longitudinal cracks form along the stems of some plant species because of freezing sap.  Water from the ground is then drawn out through the cracks in the stem and freezes upon contact with the air.  These beautifully intricate ice structures swirl and curl into flower-like structures as the water oozes out through the cracks and freezes.  FNAI scientists observed these frost flowers along the edge of a marsh a few days ago on a cold morning at Flint Rock Wildlife Management Area in Wakulla and Jefferson Counties.  Be on the watch for them on cold mornings!!

Who's Your CISMA?

Invasive, non-native plants and animals are one of the greatest threats to biodiversity and the ecological integrity of our natural areas, and therefore are a focus for FNAI.  There are many groups doing exceptional work related to invasive species, and much of that work in Florida and around the country is coordinated by regional collaborations called Cooperative Invasive Species Management Areas or CISMAS.  CISMAs are volunteer collaborations of professionals, private landowners, and concerned citizens who believe that more can get done when working together.  Participants may work for different private and public organizations with differing job duties and often differing priorities.  However, everyone unites in their efforts to eradicate or control invasive species across fencelines and political boundaries.  Bringing resources together is often a more cost-effective approach to manage the problem.

CISMA boundaries in Florida.

There are two primary ways in which CISMAs can make a difference.  First, there is direct control of invasive species through scheduled workdays.  Teams will work together to kill invasive plants (hand pulling or treating with herbicide) or do surveys to find out and document where the invasive species may be present.  Second, CISMAs participate in public events to educate the community and local land managers on the problems associated with invasive species.  Many people don’t even know that the invasive species they have in their own yard are causing a problem for conservation lands nearby!

We encourage anyone interested in the conservation of Florida’s biodiversity to become familiar with the CISMA in your area.  To find out who to contact, visit the Florida Invasive Species Partnership (FISP) website.  FISP is the umbrella organization over all of the Florida CISMAs.  FNAI is a key partner in this process; our invasive species contacts actively working with the CISMAs are Gregg Walker and Greg Jubinsky.

Map of the Month: Longleaf Pine Ecosystems

FNAI, in partnership with Florida Forest Service (FFS), has just launched our newest interactive map:  Longleaf Pine Ecosystems in Florida.  The public and our partners can now easily view data contained in the Florida Longleaf Pine Ecosystem Geodatabase (LPEGDB), a central repository for information on the distribution and ecological condition of longleaf pine.

Much of the LPEGDB data is thanks to the dedicated efforts of FFS County Foresters who field assessed almost 850,000 acres of potential longleaf in 8 months!  FNAI helped develop the rapid assessment protocol and trained 40 foresters on its use in the field.  In addition to the rapid assessment, the LPEGDB contains information from many other sources including field data collected by FNAI and our partner agencies like US Forest Service, Eglin Air Force Base, Florida Fish and Wildlife Conservation Commission, and the Water Management Districts.  To date these efforts have confirmed 2.15 million acres of longleaf in the state and we can report ecological conditions on 78% of those areas.

On the interactive map users can toggle Ecological Conditions layers to display summaries of vegetation structure and composition for the canopy, shrub, and ground layers. 

 

Healthy longleaf pine ecosystems are characterized by much more than their iconic trees.  Assessment of vegetation at different levels gives a picture of overall condition and can help guide management and restoration priorities.  In their natural condition, these fire-adapted, open landscapes have one of the highest diversities of flowering plants in North America and are critical habitat to a host of rare animals including gopher tortoises, fox squirrels and red-cockaded woodpeckers.   Land managers often focus on restoring appropriate fire regimes to help restore the natural biodiversity and ecological processes of these communities.

Check out the map and provide feedback.   The map reflects the latest version of the database– LPEGDB v.3— just published in September 2015, and we are pleased to continue our partnership with FFS to update the LPEGDB in 2016.  For latest details on the project and other longleaf links please visit our longleaf webpage.
