Marsh Treader

An extremely slender, stick-like bug with a greatly elongated head. It walks slowly across floating vegetation and water surfaces at pond margins, probing for tiny prey.

💡

Did You Know?

Its elongated head and rostrum give it a bizarre twig-like appearance, providing excellent camouflage among vegetation.

Cinnamon Bug

A bright red-and-black scentless plant bug that mimics fire bugs and other aposematic insects. Despite its warning coloration, it is harmless and feeds on the seeds of various weedy plants.

💡

Did You Know?

It is often mistaken for the unrelated fire bug due to its similar red-and-black pattern, a likely case of Mullerian mimicry.
