Acrolophus arcanella
Clemens, 1859
grass tubeworm moth
Acrolophus arcanella, commonly known as the grass tubeworm , is a small moth in the Acrolophidae. It occurs in eastern North America, where its caterpillars are known to spin silken tubes at the base of grasses or grass roots for concealment while feeding. The species has a wingspan of approximately 25 mm. Like other members of the , it was formerly classified in the family Tineidae before being reassigned to Acrolophidae based on revised taxonomic understanding.

Identification
Members of the Acrolophus are distinguished from similar small by their association with grasses and their caterpillars' habit of constructing silken tubes. Specific identification of A. arcanella from requires examination of genitalia or other subtle morphological features not reliably visible in field observations.
Appearance
A small with a wingspan of approximately 25 mm. Detailed specific to this is not well documented in available sources.
Habitat
Associated with grassy environments, as the caterpillars feed on grasses and construct silken tubes at the base of grass plants or among grass roots.
Distribution
Eastern North America. Specific records include Vermont, USA.
Diet
Larval stage feeds on grasses. feeding habits are not documented.
Host Associations
- grasses - larval food plantCaterpillars feed on grasses and spin silken tubes at the base of plants or among roots for concealment
Life Cycle
Complete with , larva, pupa, and stages. Larvae are known to spin silken tubes at the base of grasses or among grass roots, concealing themselves while feeding. Further details specific to this are not documented.
Behavior
Larvae construct silken tubes for concealment while feeding. are attracted to light, as has been observed in other Acrolophus .
Ecological Role
Larval herbivore on grasses; specific ecological impacts are not documented.
Human Relevance
Not known to be of economic significance. The "grass tubeworm " reflects its larval habit rather than any association with tubers as a crop pest.

More Details
Taxonomic history
This was formerly placed in the Tineidae (clothes moths and relatives) but has been reassigned to Acrolophidae based on revised understanding of evolutionary relationships within Lepidoptera.
Genus characteristics
Acrolophus are collectively known as "grass tube moths" or "grass tubeworm moths" due to the distinctive larval of spinning silken tubes at the base of grasses.
