Larvae of an endangered (vulnerable) butterfly Panchala ganesa loomisi were reared on eight Quercus plants. All hatchlings died when they were supplied with Q. myrsinifolia. However, the mortality was low when they were supplied with Q. acuta, Q. gilva, Q. glauca, Q. phillyreoides, Q. salicina, Q. serrata and Q. sessilifolia. Adults obtained from these seven plants were larger than wild ones. Results of the experiment suggest that these seven species of Quercus are suitable as food plants of P. g. loomisi.
In the present study, Psyche casta (Pallas, 1767) is newly recorded in Japan. Illustrations of both adults and male genitalia are provided. In addition, the taxonomic issue around this species is discussed based on morphological characters.
Eupoecilia ingens Sun & Li, 2014 is recorded in Honshu, Shikoku and Kyushu, representing the first record from Japan. A diagnosis for this species is provided based on the Japanese specimens.
Tituacia pseudodeviella sp. nov. is described with a series of photos and figures of adult, wing venation, male and female genitalia and male genital musculature. The systematic position of the genus is discussed using morphological features.
