Abstract
Since approximately 2004, outbreaks of the sciarid species Hyperlasion breviantenna Sueyoshi et al., 2022, have occurred at Shizuoka University, Shizuoka, Japan. We attempted to identify the reason for the outbreaks through ecological research. According to the results of our investigation on the annual occurrence and ecological characteristics of this species, it occurs in various habitats only in the rainy season, and adults emerge only in the morning. These individuals were only females. From the studies of this species in Tajimi city, Gifu, Japan, both females and males of this species usually emerge at the soil of forest edges rather than inside forests. The areas of forest edges where males emerged were limited depending on place. Males and females with intact wings, but only females come to houses or buildings. Small woodlands, gardens, and parks are the areas of origin in urban areas. We show that outbreaks of these insect leads are rarely nuisances because of the many fascinating characteristics of these pests.
