Identification
Distinguished from other Lasiocampidae by genitalia structure and larval . lack the pronounced wing markings seen in some Malacosinae. Larvae can be separated from tent caterpillars (Malacosinae) by differences in setal arrangement and the absence of dense communal nesting in most . Molecular data supports monophyly of the subfamily.

Habitat
Deciduous and mixed forests, woodlands, and parklands. Associated with trees including oak, beech, birch, and other broadleaf . Elevation range varies by species, from lowland to montane forests.
Distribution
Primarily Palearctic, with highest diversity in Europe and temperate Asia. Some representatives extend into North Africa and the Near East. Absent from the Americas, sub-Saharan Africa, and Australasia.
Seasonality
active primarily in autumn and early winter (September–December in temperate regions), with some variation by latitude and altitude. Larvae present in spring and early summer.
Diet
Larvae feed on leaves of deciduous broadleaf trees, including Fagaceae (oak, beech), Betulaceae (birch, alder), and Salicaceae (willow, poplar). Specific associations vary by and .
Host Associations
- Quercus - larval oak
- Fagus - larval beech
- Betula - larval birch
- Alnus - larval alder
- Salix - larval willow
- Populus - larval poplar
Life Cycle
Complete . laid in autumn on twigs or bark crevices, in this stage. Larvae hatch in spring, feeding solitarily or in small groups through early summer. occurs in silken cocoons attached to host vegetation or leaf litter. emerge in autumn; some may display extended adult periods.
Behavior
are and non-feeding, with reduced mouthparts. Males possess strongly bipectinate for detecting female . Larvae generally solitary or in small , lacking the dense communal nesting and foraging characteristic of Malacosinae tent caterpillars.
Ecological Role
Larvae function as folivores in deciduous forest , contributing to nutrient cycling through herbivory and deposition. Cocoons provide microhabitat for associates. serve as prey for including bats and owls.
Human Relevance
Occasional localized defoliation of ornamental and forest trees, though generally less severe than of tent caterpillars (Malacosinae). Of minor economic significance. Some , such as Poecilocampa populi (December ), are familiar to naturalists due to late-season activity.
