🚨 Dangerous Wasp Species
European Wasp (Vespula germanica)
Size: 12-16mm workers, 20mm queens
Color: Bright yellow and black stripes
Behavior: Extremely aggressive, can sting multiple times

Why They're Dangerous:
European wasps are highly aggressive, especially when defending nests. They can sting repeatedly, inject more venom than bees, and attack in swarms. Their stings are extremely painful and can cause severe allergic reactions.
Yellow Jacket (Vespula species)
Size: 10-16mm
Color: Yellow and black, similar to European wasp
Behavior: Aggressive when threatened
Nest: Paper-like material, various locations
Danger Level: HIGH
Activity: Most active during warm weather
Hornet (Vespa species)
Size: 25-35mm (largest wasps)
Color: Brown and yellow markings
Behavior: Less aggressive but powerful sting
Nest: Large paper nests in trees
Danger Level: HIGH
Distribution: Limited in Australia
✅ Beneficial Wasp Species
Important Ecosystem Role
Not all wasps are dangerous. Many native Australian species are beneficial, controlling pest insects and pollinating plants. These species are generally less aggressive and rarely sting humans.
Paper Wasp (Polistes species)
Size: 15-20mm
Color: Brown, yellow, and black
Behavior: Generally docile, only aggressive when threatened
Nest: Small, open paper combs under eaves
Benefit: Controls caterpillars and other garden pests
Sting Risk: LOW (unless nest disturbed)
Mud Dauber (Sceliphron species)
Size: 20-25mm
Color: Black or metallic blue
Behavior: Solitary, very rarely stings
Nest: Mud tubes on walls and structures
Benefit: Controls spiders and other insects
Sting Risk: VERY LOW
