Natural Habitat

Woodlands, forest edges, and residential areas; nesting in decaying wood, tree cavities, or damp structural timber.

Diet & Feeding

Opportunistic omnivores feeding on honeydew from aphids, plant juices, and other insects.

Behavior Patterns

Alates are reproductive individuals that emerge in swarms during warm, humid evenings to mate and establish new colonies. They are primarily nocturnal.

Risks & Benefits

Generally harmless to humans as they do not sting, but can cause structural damage if a colony is established inside home timbers. They benefit ecosystems through nutrient cycling and soil aeration.
