Family: Coenagrionidae
Commonly called pond damselflies or narrow-winged damselflies — Familiar Bluet damselflies are the small, familiar damselflies most often encountered around ponds, lakes, marshes, and slow-moving water. They are typically slender, hold their wings closed above the abdomen at rest, and often show bright blue-and-black patterns in males, with more variable coloration in females.
Members of this family are frequently seen perched on grasses, sedges, and low vegetation near the water’s edge, where they make short, fluttering flights between perches. Their abundance and approachable behavior make them some of the most commonly photographed damselflies.
Representative genera and resources:
- Enallagma civile — Familiar Bluet; a common and widespread species
- Familiar Bluet gallery — photographic examples and field context
These damselflies favor vegetated margins of still or slow-moving water, where emergent plants provide perching sites and breeding habitat. Adults are often seen in open sunlight as well as along shaded edges, moving in short, low flights through surrounding vegetation.
Key field characters of Coenagrionidae include:
- Narrow, clear wings held together above the body at rest
- Slender build with relatively long abdomen
- Strong sexual dimorphism, with males often bright blue and females more variable
- Subtle but important differences in abdominal patterning and terminal appendages
Identification within this family can be challenging, particularly among bluets (Enallagma), where multiple species share similar coloration and structure. Close observation — or detailed photographs — is often required to distinguish species with confidence.
For identification and comparison with related groups, see the linked Field Notes pages and compare:
- Thoracic striping patterns
- Abdominal segment markings (especially segments 2 and 8–10)
- Male terminal appendages
- Perching behavior and habitat
This page draws on field observations and photographic examples from the Familiar Bluet (Enallagma civile) and related bluets documented in Minnesota.
