Yellow-Legged Horntail
A large, dark-bodied wood wasp with bright yellow legs that contrast sharply with its blue-black body. Found primarily in conifer forests of eastern Asia.
Did You Know?
Like all horntails, the short horn-like projection at the tail is not a stinger but a structural feature called a cornus, present in both sexes.
Velvet Ant
Not actually an ant but a wasp. Females are wingless and covered in dense, colorful hair. Known as "cow killers" for their extremely painful sting. Parasitize ground-nesting bees.
Did You Know?
Velvet ants have been called the most indestructible insects — their exoskeleton is so tough that entomological pins bend when trying to pierce them.
