because its name is different i guess theyre not the same
Worms are invertebrates; not bugs.
if it is small and looks kinda like a caterpillar it's a ladybug larva
red worms are much smaller in diameter than earthworms, have a red tone and yellowish at the tail.
In an indoor bin red worms should be divided every 2-3 months as their castings are somewhat toxic to them.
