Cassini Periodical Cicada
A 17-year periodical cicada distinguished from related species by its all-black underside and distinctive buzzing call. It often emerges alongside M. septendecim in the same broods.
Did You Know?
Its call sounds like a rapid series of ticks followed by a buzz, distinctly different from the pharaoh-like drone of its sibling species.
Amazonian Water Scorpion
A stick-like aquatic bug with an extremely elongated body and long breathing siphon at the rear. It hangs motionless near the surface, ambushing passing prey.
Did You Know?
Despite the common name, it is not a scorpion at all and is completely harmless to humans though it can deliver a mild prick.
