The larvae feed on Fomes species.
Pupa
The pupa has a length of about 8 mm and is similar to Arrhenophanes perspicilla in chaetotaxy except with SV bisetose on A3-A6. The cremasteral spines are minute and slightly more raised and acute than in A. perspicilla.
Larval case
The larval case has a length of about 11 mm and a maximum width of 3.5 mm. It is cylindrical with thick, tough walls which are lined internally with dense, white silk. It is covered externally with brownish, matted silk and minute plant fragments.
Etymology
The specific name is derived from the Greek argus (white), in reference to the predominantly whitish color of this species.
