Insect Strength Compared To Size
The rhinoceros beetle is a colossus in insect conditions and is rated among the mightiest animals in the world in comparison to its body weight. You have probably heard that the rhino beetle can carry up to 850 times its own weight without even buckling at the knee segments, incredible!
Indeed, it is proportionally more powerful than an elephant which is the strongest land animal concerning brute force, helpful resources.
Having said this, it is worth mentioning that if an elephant were shrunk to the size of a bug its strength in relation to its mass would increase x-fold.
This is down to a phenomenon known as the scaling law formally recognized by Galileo in 1638.
The Scaling Law Preventing Insects From Getting Giant Monsters
Galileo discovered that if a sphere’s diameter is increased by two, the surface area is multiplied by 4 and the quantity eightfold. This signifies that elements of a body are not scaled up or down by the same amount.
In plain terms, if a bug grew to the size of an elephant without changing the original shape of its body, it would be so heavy in proportion to its own legs that it wouldn’t have the ability to move its carcass, let alone take eight hundred and fifty times its own weight.
It would have to radically alter its proportions starting with its legs. This can be illustrated in the growth proportions of a human being.
In the human, the mind becomes smaller and the legs larger and stronger as the individual grows to adult size. If the legs remained the same from infancy to maturity they would not have the strength to maintain the body.
Increased Need For Oxygen And Food
There are other anatomical limitations such as the insect respiratory system, which might become insufficient with the increased volume in contrast to the insect’s surface area. It might require lungs instead of just absorbing atmosphere through its spiracles to be able to satisfy its increased need for oxygen.
Furthermore, unless it had been born in a massive dung pile the size of a hillock, it wouldn’t have the ability to supply itself with the tremendous amounts of food that it would need to keep going.
So rest reassured, even if someone invented a magic hormone medication to grow, say, cockroaches to the size of a human, the resulting monsters are about as nimble as a wheel dozer with flat tires. Unless, of course, their morphology evolved.
