The Largest Beetle in Panama and Biggest in the World!

Dynastes hercules

Back in the day someone had fun with the common nomenclature process of this here big beetle-iful beauty: Hercules, Titan, or Goliath? All names assigned to beetles battling it out to earn the title of biggest on the planet. Hercules it is! Measuring up to 7.5 inches (19 cm) long that is a well deserved title.

Slowly waddling her way through the jungles of Central and South America at night in search of plants, rotten wood, and tasty fruits that have been left behind on the jungle floor no doubt by the monkeys and squirrels who take a bite of a creamy avocado, sweet mango, or juicy rose apple then throw it to the floor for their friends below. We like to call that a symbiotic relationship or, natures version of room service.

Have you ever looked at an airplane and thought to yourself - it's amazing that big beast can fly through the air? Physics was a tough subject for me so I know I am amazed by airplanes kinda like I am these beetles. They are huge but, let's just say, they got passed up in line when aerodynamic body shapes were being passed out.

Their sheer size and the way they amble clumsily through the jungle floor reminds me of a big doofy Bernese Mountain Dog - cute, gentle, huge, and harmless. But, beneath that shining armor is quite the unexpected brilliance to camouflage, weight lift, and fly.

Their translucent hindwings are tucked safely below their elytra - what we see as armor are actually forewings. At night, they are out and about flying through the air like big ole blimps in search of fermenting fruits and mates. If you have a compost pile you might find them foraging on all that smelly fruit at night and for sure you'll find their large white larvae that have hatched from their nest of about 100 eggs.

Like Katy Perry and her ever-changing looks, Hercules Beetles change colors depending on where they're hanging out - from green to yellow to dark black. As humidity increases they become darker. A beautiful and imposing insect to say the least.

Speaking of imposing, aptly named Hercules because of their strength, they are known for being the second strongest insect on the planet - able to lift 850 times its body weight, just behind the dung beetle which we have here too but we'll save that story for another day. Hercules here uses her strength to forage through wood and detritus rather than push, pull, and bury like the dung beetle.

Hercules Beetle Eyes

Like other animals of the night, their eyes are uniquely adapted to be able to see using thousands of lenses (unlike humans that have only 2) with wide open apertures that allow light in. Additionally, they utilize their antennae - located below and to the sides of their mouth and setae along their body to grip, perceive touch, sound, and spread pheromones to attract mates.

With so much happening in the jungle at night all around us, we recommend walking off some of our tasty desserts in search of its wonder. Just remember your red headlamp to enjoy it without causing harm to their sensitive eyes and interrupting their moments of predation, reproduction, and communication.

With love from Panama,
