Acrolophus piger
piger grass tubeworm moth
Acrolophus piger, commonly known as the piger grass tubeworm moth, is a small moth in the family Tineidae (subfamily Acrolophinae). First described by Harrison Gray Dyar Jr. in 1900, this species is found in the southeastern United States. The genus Acrolophus is known as "grass tubeworm moths" because larvae typically spin silken tubes at the base of grasses or grass roots for concealment while feeding. Adult wingspan is approximately 16 mm.
