White-top Pitcherplant (Sarracenia leucophylla)

Pitcher plants have very specialized leaves that form elongated conical tubes. They are carnivorous, and capture their prey, primarily insects, by drowning them in these structures. We have two species of pitcher plant moths, genus Exyra, in Florida that are not only able to avoid capture, but eat the pitcher plants.

FNAI scientists recently observed pitcherplant mining moths (E. semicrocea) at two state forests in white-top pitcherplants (Sarracenia leucophylla), a globally vulnerable species which is restricted to the SE region from the Florida panhandle to southeastern Mississippi.

These moths use the pitchers for food, shelter, and protection from predators. They live most of their life in the pitchers as caterpillars, slowly eating the insides of the walls, but leaving the outer surfaces intact and even repairing unintentional holes using silk. Younger caterpillars protect themselves by causing the tops of the pitchers to close up like a cap and older ones use silk to make a net-like barrier across the opening of the pitcher. The caterpillar overwinters inside of a pitcher and then goes to different pitcher to make a cocoon in, sticking itself to the side with silk after making a drain hole at the bottom of the pitcher. Adults hide in the pitchers during the day, feed from extrafloral nectaries on the pitchers towards dusk, and then fly out to mate and/or lay eggs. Much of the information about this species is known from research by Jessica D. Stephens and Debbie R. Folkerts (published here).

Update from the Field: Rare Plant Monitoring

FNAI botanists are working with the U.S. Forest Service and the U.S. Fish and Wildlife Service this week to monitor populations of the federally-threatened Florida Skullcap (Scutellaria floridana) in the Apalachicola National Forest. The permanent plots will be monitored before and after restoration activities.  In addition to Florida skullcap density, species composition and cover in all forest strata (canopy, midstory, groundcover) are being recorded.

Noteworthy Discoveries: Jingle Bell Orchid in Hendry County

During recent field surveys to document rare plants at
Spirit of the Wild Wildlife Management Area, FNAI botanists located several thriving populations of the jingle bell orchid, (Harrisella porrecta, syn. Dendrophylax porretcus) in a strand swamp growing on branches of the bald cypress (Taxodium distichum). The fruits of this tiny leafless orchid are a well-named characteristic, as they do look just like little bells. According to the Atlas of Florida Vascular Plants, jingle bell orchid has never been collected in Hendry County, so FNAI scientists were excited to discover these populations.

Gary Knight Retires as FNAI Director

Please join our staff in extending warm wishes to Gary Knight, who retired from FNAI last month.  Gary joined FNAI in 1990 as staff botanist, and served as Director from 1995 to the present.  Under Gary’s steady leadership, FNAI has continued to grow and thrive as one of the premier heritage programs in the NatureServe international heritage network.  Gary forged strong partnerships with key state and federal agencies and NGOs, and expanded FNAI’s role in several important conservation efforts around the state, including scientific evaluation of Florida Forever land acquisition proposals, mapping and monitoring of 2.6 million acres of natural communities on conservation lands, and creation of an invasive species database for Florida.  During Gary’s tenure FNAI scientists have added or updated approximately 21,000 documented occurrences of rare species and natural communities to our element occurrence database, for a current total of more than 35,500 occurrences across the state.  Gary was the driving force behind three major FNAI publications:  field guides to the rare plants and animals of Florida, and the Atlas of Florida’s Natural Heritage.  Through it all Gary fostered a supportive, team-oriented, and fun work environment for the many staff who have been part of FNAI over the past twenty years.  We will miss his leadership but wish him the best in a well-deserved retirement.

Gary will be succeeded as FNAI Director by Dan Hipes.  Dan started work with the Florida Natural Areas Inventory in 1993 as a field biologist.  He was promoted to Senior Zoologist in 1995 and has served as the Chief Scientist and primary assistant to Gary since 2001.  Dan’s experience provides for a seamless transition and continued growth in FNAI’s partnerships and influence in Florida conservation.

Update from the Field: Gearing Up for Another Busy Fall Field Season!

FNAI staff are in the field year-round, but fall and spring are especially busy times.  That looks to be especially true this year, with FNAI biologists working in at least 27 different sites across 24 counties over the next few months!

This fall's fieldwork includes ecological sampling to inform land management, natural community mapping to reflect restoration efforts, rare plant surveys and monitoring, invasive plants surveys, and surveys for reptiles and amphibians.  

Our partners for these projects include the Florida Fish & Wildlife Conservation Commission, Florida Forest Service, Florida Department of Environmental Protection, and The Nature Conservancy, among others.

FNAI has recently hired three skilled field biologists to support these efforts.  Data from these projects informs the efforts of conservation land managers around the state, and helps build our Element Occurrence database of rare plants, animals, and natural communities.

When it comes to science to inform conservation, FNAI has the state of Florida covered!
