Why are ladybirds called ladybirds when they are not birds or ladies?

Question

and, why are butterflies called butterflies when they aren't flies or made of butter, as well as dragonflies too? Where did these names come from?..

Answer 1

Thanks to your question I've discovered that ladybirds are what we call ladybugs. The dictionary (which doesn't give the origin of either word) notes that ladybug is the US variant of ladybird ... but I'm Canadian. Where are you (and your ladybirds)?

Answer 2

Because they're lady-like and birds eat them.

Because they "flutter by" you, and spoonerisms are fun.

Dragonflies are just amazing, as well as Damselflies.  

But really, search "etymology" plus the word you want to learn about and you should find a history of the word and how it has evolved.  

There are also some really great books out there that deal with questions like that.  

Answer 3

The same as sweetbreads, which are not sweet or breads
