The Elusive “Scorpion Beetle” – The Only Known Insect Capable of Inoculating Toxins Through Its Antennae

Beetles are generally regarded as harmless to humans. Out of the over 350,000 documented species of beetle, only three are actually known to bite people, and only if they feel threatened. However, there is another species that few sources mention. Onychocerus albitarsis, aka Scorpion Beetle, is the only known insect capable of stinging humans with its antennae and delivering a painful toxin.

First described in 1859 by famous English entomologist Francis Polkinghorne Pascoe, the scorpion beetle is considered by many experts a fascinating case of convergent evolution. While all other known insects deliver venom or toxins by biting with fangs or stinging with a structure used exclusively for this purpose, e.g. a bee’s stinger, the scorpion beetle does it through its two long antennae, which research has shown have evolved to closely resemble a scorpion’s segmented tail.

This Buddha Sculpture Is Made from 20,000 Dead Beetles

Japanese artist Yoneji Inamura spent six years of his life collecting 20,000 beetles of different varieties and using them to create a five-foot sculpture of a popular Buddhist deity.

It’s unclear how and when exactly Inamura started catching and collecting beetles. Some sources claim that it was during his days working for the local railroad, in Itakura, Japan’s Gunma Prefecture, after noticing that the rhinoceros beetle’s horn resembled the fingers of the Buddhist deity, while others say that he was helping local children collect beetles and just became fascinated with them. Living in a rural area of Japan, Inamura was always surrounded by various types of beetles, including rhinoceros beetles, winged jewel beetles, drone beetles, longhorn beetles, just to name a few, and he dedicated most of his free time to catching and adding them to his collection.

Bugs the Size of Your Hand – The Titan Beetle

As its name suggests, the Titanus giganteus, or Titan Beetle, is a giant of the insect world. Adults can grow up to 6.5 inches (16.7 cm) long and have incredibly strong jaws that can snap wooden pencils in half, so just imagine what they could do to your fingers. Luckily, these scary-looking bugs are quite harmless to humans.

The Titan beetle is one of the most mysterious creatures on Earth. It lives unobtrusively deep in some of the South America’s  hottest tropical rain forests and only ventures out when seeking out mates. The larvae of this amazing insect have never been found, but judging by the large boreholes found in dead trees in their natural habitat, scientists believe Titan beetle grubs feed on decaying wood below ground for several years before reaching maturity. The size of these holes suggests the grubs are around two inches in diameter and up to a foot long. Just like the Atlas Moth, the Titan beetle doesn’t feed during its adult life cycle, using the reserves gathered in its pupa stage to fly around long enough to find a mate. Because they mostly sit around waiting for males to seek them out and fertilize their eggs, females have rarely been spotted.
