A dragonfly that hangs in the air and touches the surface of the water is usually not laying eggs. This behavior may be that it is catching food.
Dragonfly larvae grow in water, where they capture insects and small aquatic creatures for food. Therefore, when adult dragonflies see prey in the surrounding water, they may hang in the air and try to catch the food, which often results in their water-struck behavior.
However, some dragonfly species do lay eggs in water, but the spawning behavior usually does not appear as a simple "dragonfly touching the water." The spawning process involves complex behaviors and movements, often requiring the dragonfly to fly across the water and perform specific egg-laying movements.
