説明

1) Hitherto, Andropogon virginicus was known as only one natural food plant of Ypthima multistriata in Hyogo prefecture. However, on April 3 in 2010, I found a larva of Ypthima multistriata feeding on a leaf of Carex blepharicarpa at the sunny opened field in Kakogawa-city. This finding coincides to the report by Kubo (2010) that a female of Ypthima multistriata laid an egg on a native or withered leaf of a kind of Carex although it was shady place in the field. 2) Some larvae of Ypthima multistriata voluntarily transferred from Gramineae to Carex as food plants while rearing in the laboratory. 3) There is only one record of November 5, 2006 on the natural second brood of Ypthima multistriata in the field of Kakogawa-city. Afterward, we could confirm that the second brood emerged from the latter part of August to the same part of October by laboratorial rearing in 2009 and 2010. However, we have not yet observed any natural second brood in the field since 2007. On this account, we would like to continue further field observations and intensive rearing in the laboratory, considering effects of atmospheric phenomena or conditions of food plants for larvae in the field.
