Note on the frontal tuft color variation and host plant record of Stigmella fumida Kemperman & Wilkinson, 1985, with first record of S. omelkoi Puplesis, 1984 from Kyushu (Lepidoptera: Nepticulidae)

Abstract

Stigmella fumida Kemperman & Wilkinson, 1985 (Lepidoptera: Nepticulidae) is a common species in Japan with a black frontal tuft at the vertex. During the survey, one specimen with a yellowish-orange frontal tuft was collected. Based on morphological comparison and DNA barcoding, this specimen was S. fumida, and thus, it was revealed that this species has a color variation in the frontal tuft. We also collected S. fumida from Quercus variabilis, a new host plant.
