Slaty Skimmers are comfortable in most environments, so they are common across the entire continent. Other members of the Libellula genus prefer more specific habitats and are less commonly observed. Look for Slaty Skimmers around any water source: springs, creeks, swamps, marshes, lagoons, etc. Flooded areas are also good conditions for temporarily expanded territories. Look for them throughout the summer months in sunny areas.
Females mate with males near water and flick their fertilized eggs near the banks, or edges, of the water. Larvae (called naiads) remain underwater, feeding on aquatic insects. They look like insects themselves in this life stage. When ready, they crawl onto land, molt and become winged adults.
