How did it come to be that so many types of creatures typically known as worms are actually insect larvae? Silkworms are not actually worms at all, but larvae of a type of moth. Another example being the Maguey worm, which is supposedly the worm in some types of tequila and also not a worm, actually also a type of moth-larvae?
I find it curious that Wikipedia would have a creature with the word worm in its title, and then the first thing they tell you about it is that it is actually an insect. These are just the two examples I came across, there are probably more.
