Homaledra heptathalams is known in Florida from Sabal palmetto. The larvae of this species are solitary, while H. sabalella are in colonies.
Caterpillars feed on the upper and lower leaf surfaces, producing large quantities of "frass" that is often the first conspicuous sign of infestation. Tissue between the leaf veins is usually the preferred food, whereby the veins remain intact giving the leaf a skeltetonized appearance.
In Florida, larvae are present throughout the year and complete five generations per year in northern Florida.
