17 Rather Horrifying Facts About Bugs That'll Confirm All Your Fears

Flies poo every time they land.

Okay, before we go on – not all of these are bugs.

Bugs, scientifically speaking, are small insects with "beak-like" piercing mouths, like fleas and midges. So spiders, slugs, and wasps are not technically bugs, but you get the idea.

1. There is a type of wasp that can control the brains of cockroaches, basically turning the roach into a zombie.

The jewel wasp will sting the cockroach in a specific area of its brain that controls the roach's escape reflex. It will then lead the cockroach to it's burrow, using the roach's antennae as a lead, and lay an egg inside the abdomen of the roach. Without a functioning escape reflex, the roach will remain inside the burrow until the egg hatches and the larvae inside will eat its internal organs.

2. Some species of cockroaches can live for up to a month without a head.


Unlike humans, because cockroaches have an open circulatory system with little pressure, beheading will not result in a lot of blood loss and instead, the neck will seal off by clotting. A lot of the functions of a roach brain are decentralised, so it can breath without it and maintain simple reflexes needed for movement.


7. Tarantula venom is actually no more dangerous to humans than bee or wasp venom, unless you're allergic to it.

If you keep a tarantula as a pet, you're more in danger from the hairs on its abdomen than can cause rashes.


8. Spider webs actually spring towards prey because spiders cover it in a electro-static glue, which moves towards all charged particles, including prey.

The glue also distorts the Earth's magnetic field a few millimeteres within the radius of the web.

10. Caterpillars only have six legs, just like butterflies and moths.

They often have fake little legs called "prolegs", which are short stubby protrusions that help prop their big bodies up, which is why they look like they have more than six legs.


12. The death’s-head hawk moth has a skull pattern on its abdomen and can release a high-pitched shriek when irritated.

Because a moth with a skull on it is obviously really creepy, it's commonly used as symbolism in a lot of art and literature, including on the Silence of the Lambs movie poster.

16. Scorpions have extremely slow metabolisms and some species have been known to go a year between meals.

They have a very leisurely approach to hunting, which mostly involves sitting and waiting, meaning they use very few nutrients. You definitely can't trust anything that can go this long without eating.

17. Nearly every time a housefly lands, it defecates or regurgitates.

Flies have a liquid diet, which means everything goes right through their little digestive systems and everything you own and love is covered in fly poo and sick.
