Habitat Preferences of Southern hawker Through Different Life Stages
The naiads of southern hawker inhabit freshwater bodies, such as ponds or slow-moving streams, where vegetation is abundant. They crawl on submerged plants and debris, hunting for small aquatic organisms. To find them, search by gently moving aside aquatic plants or examining the underside of rocks in shallow water. Adult southern hawker are typically found near the same water bodies, but they're also attracted to open areas for feeding and mating. Look for adults in clearings, along forest edges, or meadows close to water sources during daylight, especially in sunny conditions when they're most active. For observation, visiting these areas and keeping an eye on the airspace a few feet above the ground or water can be productive.

How and Where Can You Find Southern hawker at Different Life Stages
Egg Eggs of southern hawker are laid in water or on aquatic plants. To find them, inspect the stems or leaves of submerged plants around the edges of ponds or slow-moving streams.
Naiad Southern hawker naiads are aquatic and can be found in ponds, lakes, or slow-flowing streams. Use a net to gently scoop through underwater vegetation, mud, and debris where they may be hiding.
Adult During emergence, southern hawker naiads climb onto vegetation to transition into adults. This stage can be observed in early morning or evening by inspecting plants near the water's edge where naiads may climb to molt.
Southern hawker adults can be located near bodies of water where they hunt for prey. Look for them patrolling or perched on twigs, leaves, or on the ground in sunny, open areas adjacent to water sources.

Southern hawker is a voracious predator, active in both its naiad and adult stages. In the aquatic naiad stage, they ambush or chase down prey. As adults, they catch prey in flight with their precise aerial maneuvers. The primary motivation for such predatory behavior is to satiate their hunger. Southern hawker's diet leans heavily towards flying insects, like mosquitoes and mayflies, effectively controlling pest populations.
