 Updated: 8/19/2019; Authored By Staff Writer; Content ¬©www.InsectIdentification.org




A deep shade of turquoise graces the Azure Bluet, a small, slender damselfly at home in a large part of the continent.



The Azure Bluet is often seen flying near water sources that are slow-moving if they have a current at all. Ponds, marshes, bogs, and lakes are all great habitats for this type of damselfly that feeds on small flying insects. The striking blue color is seen on both males and females. A single blue band on each side of the thorax sits above more blue. A male has two bright blue 'eye spots' that sit on the backside of his round eyes. The last few segments of the abdomen are blue with a hint of black on the topside of the last segment. The female has two large blue spots on the 7th and 8th segments of her black abdomen. Azure Bluets are most active in summer.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
