Nupponen, K. & Ahola, M. 2001: Notes on the biology of Pterophorus volgensis (Möschler, 1862) with description of the larval stage (Lepidoptera, Pterophoridae). - Entomol. Fennica 12: 22-27.

A population of Pterophorus volgensis (Möschler, 1862) was found at the end of May 1998 at Mount Verbljushka in the Orenburg oblast in the southern Ural Mountains. In the next spring, 22 larvae of this rare taxon were found on Rindera tetraspis (Pallas) in the same locality, and 11 moths were bred. The biology and the distribution of the species are discussed. The larva of P. volgensis is described on the basis of material preserved in ethanol. Some drawings of mouthparts and chaetotaxy are given.
