Florida Leafwing

The Florida Leafwing (Anaea troglodyta floridalis) is native to Florida. It can be found in the pine rocklands of Florida. The Leafwing was once found throughout Miami -Dade, and Monroe counties. This imperiled butterfly is now found in only one place on Earth, the Everglades National Park. The causes of its decline are the destruction of pine rockland habitat, the introduction of exotic plants and insect species, fire suppression, the use of insecticides for mosquito control, and collecting.

When in flight, the Florida leafwing’s upper side of its wings is red or bright orange. At rest, the lower side of the wings are visible and are brown or gray, which makes the butterfly look like a dead leaf. The front wing is slightly hooked, and the back wing has a pointed tail. Its dead leaf coloration is effective camouflage in its rockland habitat. A leafwing’s wingspan is between 3 to 31/2 inches wide.

Eggs are laid on the leaves of the host plant so caterpillars can eat the leaves. Young caterpillars will make a resting perch from a leaf vein. The older caterpillars live in a rolled-up leaf.

Florida leafwing caterpillars feed only on pineland croton (Croton linearis), its larval host plant. This shrub grows in the understory of pine rockland habitat. Leafwings are dependent on the health of their host plant. The croton and other plants in the pine rockland are dependent on fire to maintain an open rockland where it reduces the competition and infestation of non-native species.

The Florida Leafwing is federally endangered. Scientists at the Everglades National Park are working with conservation groups to ensure that the endemic Florida leafwing does not disappear into extinction.

Ghost Orchid

The Ghost Orchid (Dendrophylax lindenii,) is rare and endangered. There are only an estimated 2000 left in Florida. This orchid is prized for its long, white delicate petals. It is leafless and its roots attach to the host tree. The mass of green roots clings tightly to the trunks. It is distinguished from other species of orchid by the presence of thin white markings dotting its roots.

The Ghost Orchid gets its name from its ability to move at night. It appears as if it’s floating, like a ghost.

The Ghost Orchid is pollinated by the Giant Spinx Moth, whose long tongue can reach the nectar that is not accessible to many insects. The swamps of cypress, pond apple, and palm trees are its preferred environment. The orchid’s specific habitat requirements are high humidity, mild temperatures, and dappled shade.

The Ghost Orchid does not flower reliably. It will typically flower one to two weeks once a year. It requires a specific fungus (mycorrhizal) to be able to thrive. because it is leafless, the orchid relies on its roots to produce sugars from sunlight. The Ghost Orchid has a symbiotic relationship with the fungus as it gathers nutrients from it in exchange for extra sugars.

Habitat destruction and development, as well as over-collecting, have been responsible for the decline of ghost orchid populations. The Ghost Orchid is a protected species in public land areas.

With gratitude to Jay Staton for his patience and perseverance in capturing this rare sight.

“A ghost orchid’s flower takes, on average, 2 days to fully open. This short video shows the remarkable beauty of the most sought-after orchid in the world, including background sound that gets you in the mood.”
