Eilema

Eilema is a genus of moths in the family Erebidae. These moths are characterized by their generally small to medium size and often brightly colored forewings, which can display a variety of patterns and hues. The hindwings are typically less conspicuous, often being a uniform color or lacking significant markings. The larvae of Eilema moths are known to feed on lichens and algae, a specialization that influences their habitat preferences. They are found in a wide range of environments, from tropical rainforests to temperate woodlands, with different species adapted to specific ecological niches.

The genus Eilema is distributed across the Old World, with a significant presence in Africa and Asia, and some species extending into parts of Europe. Their life cycle involves egg, larval, pupal, and adult stages. The adult moths are primarily active during the day or at dusk, though some species may be nocturnal. Their bright coloration can serve as a warning signal to potential predators, indicating unpalatability, a phenomenon known as aposematism. Due to their varied appearances and widespread distribution, the taxonomy and classification of Eilema have been subject to ongoing research and revision by entomologists.
