Some types of moth

Hi,

"Some types of moth eat..."

In the above example, 'moth' is used as a singular word. Should we always use a singular noun in these types of sentences?

No.

'Some types of yachts have auxiliary engines'.

'We need help with some types of projects'.

Do yo mean that "Some types of moth eat..." is incorrect?

I'm a native speaker of English, and even I am uncertain of the rules for these kinds of structure(s).
