• Behavioral Traits: European Hornets are known for their aggressive defense of their nests. They are also attracted to sugary substances, making outdoor dining areas a potential hotspot for encounters.
• Significance for Homeowners: Their large nests can pose a risk of structural damage, and their painful stings can lead to allergic reactions in sensitive individuals.

Bald-faced Hornet (Dolichovespula maculata) #

• Appearance: The Bald-faced Hornet is easily recognizable by its black body and distinctive white markings on its face and abdomen. They are about 0.5 to 0.75 inches long.
