A visual attractant for attracting a target insect include a substrate having a pixelated pattern portion defined by a plurality of blocks having a characteristic dimension that is within an order of magnitude of the size of the target insect. The plurality of blocks are colored to be highly reflective in a wavelength range selected to attract the target insect. A background portion is lighter in color than the pixelated pattern, to contrast sharply therewith. The blocks are clustered on the substrate such that most of the plurality of blocks define one or more irregular elongate streaks on the substrate. The pixelated pattern may be applied to a fly tape or to a pillar device, which may be adhesive.一用於吸引一目標昆蟲之視覺性引誘器係包括一基材，其具有由複數個區塊所界定的一像素化圖案部分，該等複數個區塊具有位於目標昆蟲尺寸的一數量級內之一特徵維度。複數個區塊被著色以在經選擇以吸引目標昆蟲的一波長範圍中具高度反射性。一背景部分在色彩上比像素化圖案更淺，以與其敏銳地對比。區塊係叢集於基材上，俾使複數個區塊界定基材上的一或多個不規則長形條紋。像素化圖案可被施加至一蠅黏帶或施加至一條柱裝置，其可為一黏劑。
