I recently ran across a term I either haven't heard before or hadn't paid attention too before. Cluster midge??? I thought it was a pattern, but I'm thinking now that "cluster" may be a term used to describe a general pattern that could match alot of different midges? At least when I've googled I haven't found just one pattern for a cluster midge, but alot of them.

Anyway, I hate to show my ignorance, but I'm confused.

as always any help or clarification is greatly appreciated,
