Lacking the ability of their larger counterparts to loudly profess their desire to mate, small tree crickets were observed chewing holes in the center of a leaf and sticking their head and forelegs through the opening. With their noisemaking wings now positioned at the center of this do-it-yourself megaphone, the diminutive tree crickets were able to double or triple the volume of their calls.

With the colony residing in tunnels, any openings are the primary line of defense against letting other invading ant species or potential parasites in. With their flat, saucer-shaped heads, Door Head Ant soldiers simply wedge their massive heads into the entrance of the colony, effectively plugging up the nest.

Unlike most spiders, their bodies are long and stick-like, helping them blend into their surroundings. In addition, two of their eight eyes are large and forward-facing, giving them surprisingly good eyesight at night – even better than that of an owl. But it’s not their physical appearance or amazing night vision that make these spiders so unique, it’s how they use their web.

Most species of caterpillars will molt five times before entering the pupal stage – the last stage of development before transforming into an adult moth or butterfly. So what happens to all of those old exoskeletons?

With a name like Dracula Ant, you might venture a guess as to why this species received its common name. But rather than the image of a rogue ant roaming the landscapes of Southeast Asia and Australia in search of random victims, in reality they engage in “nondestructive cannibalism”, drinking the blood of their developing young without killing them. Creepy, but not deadly.

When you’re a small frog in the jungle, you best be on the lookout as you’re on the menu of a variety of other animals. At about a half inch in length, frogs in the family microhylid – known as narrow-mouthed frogs – certainly fall into that category. But thanks to the unusual relationship some of these frogs in Peru, India and Sri Lanka have developed with different species of rather large tarantulas, they have a unique defense …an eight-legged bodyguard.

The Western Amazon Ant is in a genus of ants commonly called Kidnapper Ants. They are obligatory social parasites – unable to feed themselves or even take care of the rest of the colony. To handle these essential tasks, they are reliant on a totally different species of ant in the genus Formica.

Aside from looking like a seed in shape, coloration, and size, the Australian Walking Stick’s eggs have evolved to have their own detachable cap (called a capitulum) that’s also prized by the hungry ants.

The weather-predicting myth of the Woolly Bear has been passed down since colonial times. The folklore holds that when you see a caterpillar in autumn, the thicker the reddish-brown stripe, the milder the winter ahead. If its coloration is dominated by the thicker black bands, then we’re in for a doozy of a winter.

Looking much like a roly-poly, a unique species of marine isopod is known to parasitize eight species of fish. And while it is not uncommon for fish to have parasites, this species is the only known pest to replace a host’s organ. Which organ, you might ask? We present, the tongue-eating louse.
