A diverse assemblage of moths feeding on aphid honeydew
Kota Sakagami,Shinji Sugiura 한국응용곤충학회 2018 Journal of Asia-Pacific Entomology Vol.21 No.1
Adult butterflies and moths (Lepidoptera) use their proboscises to feed on flower nectar and other types of liquidfood. Aphids frequently secrete honeydew from their anuses, attracting various types of insects, such as ants. Adult lepidopterans are also known to feed on aphid honeydew. However, very few studies have clarified thespecies composition and morphology of moths feeding on aphid honeydew. In late June 2017, we found nocturnalmoths sipping honeydew secreted by Shivaphis celti and Sitobion cornifoliae (Hemiptera: Aphididae) onleaves of Celtis sinensis (Cannabaceae) and Cornus kousa (Cornaceae), respectively, at the edge of a secondaryforest in central Japan. The moths were observed to uncoil their proboscises and feed on honeydew on theleaves. No moths were observed to feed on honeydew directly from aphids. Nocturnal moths of 60 species (11families) and 16 species (7 families) were collected from honeydew on Ce. sinensis and Co. kousa leaves, respectively. Eleven moth species were shared between the two types of honeydew. The most abundant species,Oncocera semirubella (Lepidoptera: Pyralidae), accounted for 44.7% of all individuals. The sex ratio of O. semirubellawas female biased. Of the 65 moth species collected on aphid honeydew, 52.3% (34 species) have beenpreviously reported to visit flowers. Moths visiting honeydew had relatively short proboscises and small bodysize. These results suggest that aphid honeydew is an important, accessible food resource for moths of small size.

A new Ericaceae-feeding species of Agonopterix (Lepidoptera, Depressariidae) from Japan
Hazumu Arashima,Sadahisa Yagi,Kota Sakagami,Toshiya Hirowatari 국립중앙과학관 2023 Journal of Asia-Pacific Biodiversity Vol.16 No.1
A new species of the genus Agonopterix Hübner (Lepidoptera: Depressariidae), A. asebiella Arashima, Yagi & Hirowatari sp. nov., has been described in Japan. Images of the imagoes and the male and female genitalia and partial details of the biology are provided with similar species for comparison.
