Identification
Larvae can be distinguished from other oak-feeding by their slug-like, slimy appearance and skeletonizing feeding pattern on oak leaves. require examination of wing venation and genitalia for definitive identification. Distinguished from related Caliroa by subtle morphological features of the and saw (ovipositor).
Appearance
are small, dark with a compact body form typical of the Caliroa. Larvae are slug-like in form, with a slimy or appearance characteristic of Caliroa , and possess reduced thoracic legs.
Habitat
Associated with oak-dominated forests and woodlands. Larval is the foliage of oak trees.
Distribution
Documented in North America. Specific range details are poorly documented; iNaturalist records suggest occurrence in the eastern and central United States.
Diet
Larvae feed on oak (Quercus) leaves, skeletonizing the leaf tissue between the .
Host Associations
- Quercus - larval food plantOak leaves are consumed by larvae, which skeletonize the leaf surface.
Life Cycle
Complete with , larval, pupal, and stages. Larvae are free-feeding on oak foliage. likely occurs in soil or leaf litter, though this has not been explicitly documented for this .
Behavior
Larvae feed gregariously or solitarily on oak leaves, consuming tissue between leaf and leaving a characteristic lace-like remnant. When disturbed, larvae may drop from foliage on silken threads.
Ecological Role
Herbivore that contributes to nutrient cycling in oak . Larval feeding damage is generally minor and not considered economically significant.
Human Relevance
Occasional minor pest of ornamental oaks. No significant economic or medical importance documented.
