Thanks for the added information. I'm guessing that the bug in question is in fact a beetle from the family Coccinellids. Relax (not worrying and having a homebrew optional), because most coccinellids are beneficial, as they feed on aphids which are bad for hops.
Do they look anything like this?:
That would be the Exochomus quadripustulatus, which feeds on scale insects which are likely trying to eat your hops!
(Special thanks to Google and Wikipedia, I'm not much of a biologist, I just took an insect class about a year ago)
