Downy Emerald
Cordulia aeneaAlso known as Downy Emerald Dragonfly
Downy Emeralds patrol woodland ponds and nutrient-poor waters with swift, low-level flights along shaded margins. Males aggressively defend sunny clearings, perching vertically on overhanging foliage between territorial loops. Females deposit eggs by dipping their abdomens into floating vegetation or moss-lined banks.
