The Plecoptera are an order of insects, commonly known as stoneflies. Some 3,500 species are described worldwide, with new species still being discovered. Stoneflies are found worldwide, except Antarctica. Stoneflies are believed to be one of the most primitive groups of Neoptera, with close relatives identified from the Carboniferous and Lower Permian geological periods, while true stoneflies are known from fossils only a bit younger. The modern diversity, however, apparently is of Mesozoic origin.
Plecoptera are found in both the Southern and Northern Hemispheres, and the populations are quite distinct, although the evolutionary evidence suggests species may have crossed the equator on a number of occasions before once again becoming geographically isolated.
All species of Plecoptera are intolerant of water pollution, and their presence in a stream or still water is usually an indicator of good or excellent water quality.
Stoneflies have a generalised anatomy, with few specialised features compared to other insects. They have simple mouthparts with chewing mandibles, long, multiple-segmented antennae, large compound eyes, and two or three ocelli. The legs are robust, with each ending in two claws. The abdomen is relatively soft, and may include remnants of the nymphal gills even in the adult. Both nymphs and adults have long, paired cerci projecting from the tip of their abdomens.
They terrorize and
tyrannize democracies
Their narrow minds still nothing
learned from history
The seeds of hate acquired from
their ancestry
Spreading like a cancer in societies
They¹ve got the poison inside
Rivers of pesticide
Skin-headed minions -
they¹re deaf, dumb and blind
Machind-like in body - robotic in mind
Stone evil - inherited sin
Stone evil - infected from within
They can¹t leave it -
they can¹t break the spell
Under orders to obey
It was meant to last a thousand years
It took the world into dismay
Stone evil - stone evil
If you¹re gonna throw the torch at us
Don¹t expect to not get burned
It¹s time to stand - and fight the right
This is the lesson we have learned
They¹re marching to a different
beat and glorify
The darkest times when innocent
were crucified
They paralize and sterilize the
masses¹ minds
They desecrate man¹s dignity -
desensitize
They¹ve got the poison inside
Rivers of pesticide
Skin-headed minions -
they¹re deaf, dumb and blind
Machine-like in body -
robotic in mind - evil
Stone evil - inherited sin
Stone evil - infected from within
Stone evil - inherited sin
