Japanese Giant Water Bug
Known as 'ta-garame' in Japanese, this is one of Japan's largest aquatic insects. A fearsome ambush predator that can catch small fish and frogs. Has declined dramatically due to habitat loss.
Did You Know?
Males of this species guard the eggs, which the female glues to emergent vegetation above water, by periodically climbing up to moisten them.
Jewel Bug
A dazzling metallic green and red shield bug from South and Southeast Asia. Its brilliant iridescence makes it one of the most beautiful hemipterans.
Did You Know?
Its metallic coloration is structural rather than pigment-based, produced by nanostructures in the cuticle that reflect light.
