Abstract

Four species of clearwing moths found in Sakhalin Island in July 2021. Pen-nisetia hylaeiformis (Laspeyres, 1801), Sesia yezoensis (Hampson, 1919) and Synanthedon bicingulata (Staudinger, 1887) were collected using synthetic sex pheromones. Females of Synanthedon herzi Špatenka et O. Gorbunov, 1992 were collected from inflorescences of Eupatorium chinense L. (Asteraceae). Synanthedon bicingulata is recorded for the fauna of the island for the first time. Pennisetia hylaeiformis is represented by the subspecies assimilis Arita, 1992. For each of the collected species, data on the distribution, larval host plants, and sexual activity of males are given.

Highlights

The first information about Sakhalin Sesiidae was published by the famous Japanese entomologist S
The only female of the first mentioned species was collected at the end of July in “North-Saghalien (Rikovskoie)” [= Sakhalin, Timovsky District, Kirovskoye], and the only male of the second species was collected in “South-Saghalien (Shimizu)” [= Sakhalin, Kholmsky District, Chistovodnoye] in the latter part of August
We can say with confidence that the only possible larval host of this species on Sakhalin is Vitis coignetiae Pulliat ex Planch. (Vitaceae) since only this species of the family is found in this part of the island (Smirnov, 2002)

Summary

Introduction

The first information about Sakhalin Sesiidae was published by the famous Japanese entomologist S. He noted only two species, namely, “Sphecia contaminata Btlr.” and “Bembecia hylaeiformis Lasp.” (Matsumura, 1925: 118). The finding of Pennisetia hylaeiformis (Laspeyres, 1801) in Sakhalin does not raise any questions, but the indication of Glossosphecia contaminata (Butler, 1878) turns out to be very interesting. This is the northernmost point of distribution of this species (Gorbunov, 2019; Gorbunov & Arita, 2020). The exact larval host plant of this species remains unknown. (Vitaceae) as such (Gorbunov & Arita, 2020). We can say with confidence that the only possible larval host of this species on Sakhalin is Vitis coignetiae Pulliat ex Planch. We can say with confidence that the only possible larval host of this species on Sakhalin is Vitis coignetiae Pulliat ex Planch. (Vitaceae) since only this species of the family is found in this part of the island (Smirnov, 2002)
