Summary

Libellulidae is the largest family of dragonflies, commonly known as skimmers, chasers, and darters. They are widespread and easily recognized due to their distinctive coloration and wing patterns. The family includes genera such as Libellula, Plathemis, Celithemis, and Sympetrum, among others.

Physical Characteristics

Members of the family Libellulidae are characterized by stout bodies and brightly colored or banded wings. The larvae have a lower lip or labium that is developed into a mask over the lower part of the face.

Identification Tips

Look for brightly colored or banded wings in many genera. Common genera include Libellula, Plathemis, Celithemis, and Sympetrum.

Habitat

Found in a variety of aquatic habitats, usually near freshwater sources such as ponds, lakes, and streams.

Distribution

Cosmopolitan; in North America, found south of the tree line. Overall, there are about 945 species in 143 genera worldwide.

Diet

Adult dragonflies primarily feed on other insects, which they capture in flight.

Life Cycle

The life cycle includes egg, nymph (larvae), and adult stages, with nymphs typically living in water for several months to years before metamorphosing into adults.

Reproduction

Mating often occurs in tandem, and females lay eggs in or near water.

Predators

Predatory birds and other larger insects pose threats to dragonflies.

Ecosystem Role

Libellulidae play important roles as both predators of other insects and as prey for larger animals, contributing to both pest control and food web dynamics.

Economic Impact

They may aid in the control of mosquito populations, which can have positive economic effects.

Cultural Significance

Some species are admired for their beauty and are popular in entomological collections and photography.

Evolution

The family Libellulidae is considered to have evolved with traits that allow for efficient flight and predation.
