Habitat
Associated with aspen forests and woodlands. Larval consists of webbed leaf shelters on trees. Specific microhabitat preferences for are poorly documented.
Distribution
Recorded from Alberta, Manitoba, and Saskatchewan in Canada. The distribution appears centered in the prairie provinces, likely corresponding to the range of its primary , trembling aspen (Populus tremuloides).
Seasonality
period and larval activity timing are not well documented in available sources. As with most temperate , adults likely during summer months.
Diet
feed on aspen (Populus tremuloides) and possibly related Populus . They construct silken webs on foliage while feeding. feeding habits are unknown but likely include nectar or not feeding at all.
Host Associations
- Populus tremuloides - larval Trembling aspen, primary
Life Cycle
with , , , and stages. Larvae are web-forming that feed gregariously or solitarily within silken shelters on aspen foliage. Specific details of egg deposition, site, and stage are not documented in available sources.
Behavior
exhibit web-building , constructing silken shelters on foliage for protection while feeding. This is characteristic of many and related groups. behavior is poorly known.
Ecological Role
As a folivore, contribute to in aspen and serve as for . The is part of the diverse of associated with and temperate deciduous forests.
Human Relevance
Minor potential as a forest pest when are high, though not considered economically significant. The 'Aspen ' suggests occasional notice by forest managers. No other documented human interactions.
