Homaledra is a of small in the Pterolonchidae, native to North and South America. The genus includes at least four , with H. sabalella and H. heptathalama known as pests of palms in the southeastern United States. Larvae are herbivores of palms, feeding colonially on frond undersides beneath protective silk cover.

Habitat
Floodplains, alluvial forests, moist beach , mesic forests, drier forests, and prairie habitats. Within forests, abundance is higher in dry habitats than wet habitats; open understory promotes compared to shrub understory. Associated with palms (Sabal minor and other palm ).
Distribution
North America: Alabama, Florida, Mississippi, South Carolina, Texas, Louisiana, Puerto Rico, Hispaniola, Cuba. South America: Peru, Brazil.
Seasonality
Five or more per year in the Florida panhandle to Louisiana region. stage present in late February. short-lived: males survive up to 4 days, females up to 20 days.
Diet
herbivore of native and introduced palm . Caterpillars feed on palm fronds, skeletonizing leaves from the underside.
Host Associations
- Sabal minor - larval dwarf palmetto; primary study in Louisiana

- introduced palm species - larval
Life Cycle
Caterpillars feed colonially under dense protective silk cover on frond undersides. occurs beneath silk cover within silken tubes. Five or more per year in Florida panhandle to Louisiana region. stage present.
Behavior
Strong ability with well-connected local ; dispersal limitation is minor. Colonizes tall palmettos 2.5× more frequently than small palmettos. Colonial feeding under dense silk cover. Larvae construct elongate chambers with successively larger rectangular rooms as they grow.
Ecological Role
Herbivore and pest of various palm . attack the pupal stage. Distribution among plants determined primarily by local environmental conditions rather than spatial structure or isolation.
Human Relevance
At least two (H. sabalella and H. heptathalama) are recognized pests of palms in Florida. Considered a pest of various palm species in horticultural and natural settings.
