The Zigzag Darner is a small mosaic darner of Canada and the Northern United States. It is typically found around bogs and fens later in the summer. Easily identified by its zig-zag thoracic stripes except in the far north where its range overlaps the Azure Darner which has similarly shaped thoracic stripes

Natural History


Zigzag darners tend to perch more than other types of darners. They will often perch on horizontal surfaces such as roads, rocks, logs or the ground. They also seem to be less wary than other darners and may even perch on light clothing or nets.


Cold bog ponds and pools typically with a lot of sphagnum and shallow water


Pairs are not often seen together. Females lay eggs one at a time in aquatic vegetation. They can often be found perched on sphagnum mats at the edge of open water ovipositing.
