As a notorious pedant, I have to ask: What the heck are you lot on about?
This is a weevil:

Weevils are a type of beetle with an elongated snout. There is also the Biscuit Beetle (

So what is all this talk about moths? Weevils are nothing like moths. They're not even lepidopterans.
If I had to guess, I'd think you were talking about either the adults or larvae of the Flour Moth:
