The downside to cloning as a reproductive system is that the entire population will have the same genetics and be vulnerable to the same diseases and poisons.
- Aphids don't care.
  
  Aphids do sexual reproduction in autumn. It's just spring/summer they clone.
- Wouldn't there still be random mutations caused by epigenetics over time?
  
  Sure, but the population would be so similar that it probably wouldn't make much difference.
  
  if the environment is stable , then parthonogenesis would be common. as for deleterious effects, you mostly see that inbreeding more than parthenogenesis, since if your cloning, epigenitc markers usually remain the same.
  the only thing is they wont able to adapt to sudden changes in environment or another invasive species outcompetes them.

the Clone Wars would have been a lot more interesting if the clone troopers just split/budded, would explain all the different patterns and emerging behaviors
- Get your stormtroopers the starfish cloning, trooper loses an arm, wait a week and two troopers

invasive plants do this all the time, they are hard to eradicate once they become establish.

Realizing that they reproduce via parthenogenesis, and this involves laying eggs, I think the appropriate title would be "she big, she attac". :)
It's a strange species. Common ancestor around 1988.

He make a good snak

I hope he's at least tasty

Too many crawdads are not a problem as long as you got a pot of boiling water
- They're actually quite a big problem. They dig in the sides of canals and dikes causing them to destabilise and collapse
  
  Way too many crawdads are not a problem as long as you boil the entire sea
- They have also caused the ecrevisse à pattes blanches (the native european one) to go near extinct.

Marbled crayfish are pretty cool. A new species that evolved in captivity
- Oh, these things are wild! A new species that clones itself rapidly, can carry a crayfish-killing plague, and is relatively rapidly colonizing the planet (freshwater only).
  This feels like a thing spiders do. They can produce several clutches of eggs after mating once. If, without a mate, they could just.. do that, "even a single wolf spider egg can contaminate an entire planet."
  Its a good year for crayfish sci-fi horror
  
  people often forget invasive species often bring diseases with them, that they are adapted to but in a new environment with others species that have no natural immunity, it would wipe native populations faster than the actual animal itself.

he go clack, clack, clack?
