Euclea nanina
Dyar, 1891
Nanina Oak-Slug Moth
Euclea nanina is a of slug caterpillar in the Limacodidae. The species is assigned MONA/Hodges number 4697.1. Like other members of the Euclea, it is commonly known as an oak-slug moth, indicating association with oak (Quercus) plants. The larval stage belongs to the distinctive 'slug moth' caterpillar form, characterized by a flattened, slug-like body with reduced or modified .

Identification
Euclea nanina can be distinguished from the more commonly encountered Euclea delphinii (spiny oak-slug ) by its generally smaller size and less prominent spination. The moth is relatively small with muted coloration compared to some related limacodids. Accurate identification typically requires examination of genitalia or larval characteristics, as adult Euclea can be similar in appearance.
Habitat
Associated with oak-hickory forest , particularly in dry-mesic upland forests. Larvae feed on foliage of oak (Quercus).
Distribution
Documented from the central and eastern United States, with records from Missouri and surrounding regions. The precise range boundaries remain poorly documented.
Diet
Larvae feed on oak (Quercus) foliage, based on the and -level associations.
Host Associations
- Quercus - larval plant association inferred from and -level patterns; specific oak unconfirmed for E. nanina
Life Cycle
Complete with , larva, pupa, and stages. Larvae are slug caterpillars with stinging spines or typical of Limacodidae.
Behavior
are and attracted to ultraviolet light. Larvae are slow-moving and adhere tightly to leaf surfaces, a characteristic of slug caterpillars.
Ecological Role
Larval herbivore on oak foliage; serves as prey for various despite defensive stinging spines.
Human Relevance
Larvae possess stinging spines that can cause skin irritation upon contact, typical of Limacodidae caterpillars. Not considered a significant agricultural or forestry pest.
