An attempt of wintering of Leptoglossus occidentalis Heidemann, 1910 (Hemiptera: Heteroptera: Coreidae) in Grey Heron Ardea cinerea nests

An attempt of wintering of Western conifer seed bug (Leptoglossus occidentalis) in nests of large, tree-nesting and colonial bird – Grey Heron (Ardea cinerea Linnaeus, 1758) is described. The colony is located in the city centre of Wrocław (Lower Silesia, Poland). In November 2020, at least 61 imagines in five dropped nests were observed. Such big nests might function as shelter or a food resource for nest-dwelling arthropods and provide desirable warm microclimates during winter.
